static std::unique_ptr< MidiOutput > juce::MidiOutput::createNewDevice ( const String & deviceName )

static

This will try to create a new midi output device (only available on Linux, macOS and iOS).

This will attempt to create a new midi output device with the specified name that other apps can connect to and use as their midi input.

NB - if you are calling this method on iOS you must have enabled the "Audio Background Capability" setting in the iOS exporter otherwise this method will fail.

Returns an empty object if a device can't be created.

Parameters

deviceName the name of the device to create

◆ currentThreadShouldExit()

static bool juce::Thread::currentThreadShouldExit ( )

staticinherited

Checks whether the current thread has been told to stop running.

On the message thread, this will always return false, otherwise it will return threadShouldExit() called on the current thread.

See also: threadShouldExit

◆ getAvailableDevices()

static Array< MidiDeviceInfo > juce::MidiOutput::getAvailableDevices ( )

static

Returns a list of the available midi output devices.

You can open one of the devices by passing its identifier into the openDevice() method.

See also: MidiDeviceInfo, getDevices, getDefaultDeviceIndex, openDevice

◆ getCurrentThread()

static Thread * juce::Thread::getCurrentThread ( )

staticinherited

Finds the thread object that is currently running.

Note that the main UI thread (or other non-JUCE threads) don't have a Thread object associated with them, so this will return nullptr.

◆ getCurrentThreadId()

Thread::ThreadID juce::Thread::getCurrentThreadId ( )

staticinherited

Returns an id that identifies the caller thread.

To find the ID of a particular thread object, use getThreadId().

Returns: a unique identifier that identifies the calling thread.

◆ getThreadName()

const String & juce::Thread::getThreadName ( ) const

inlinenoexceptinherited

Returns the name of the thread.

This is the name that gets set in the constructor.

◆ initialiseJUCE()

static void juce::Thread::initialiseJUCE	(	void *	jniEnv,
		void *	jContext
	)

staticinherited

Initialises the JUCE subsystem for projects not created by the Projucer.

On Android, JUCE needs to be initialised once before it is used. The Projucer will automatically generate the necessary java code to do this. However, if you are using JUCE without the Projucer or are creating a library made with JUCE intended for use in non-JUCE apks, then you must call this method manually once on apk startup.

You can call this method from C++ or directly from java by calling the following java method:

com.rmsl.juce.Java.initialiseJUCE (myContext);

Note that the above java method is only available in Android Studio projects created by the Projucer. If you need to call this from another type of project then you need to add the following java file to your project:

package com.rmsl.juce;
 
public class Java
{
    static { System.loadLibrary ("juce_jni"); }
    public native static void initialiseJUCE (Context context);
}

Parameters

jniEnv	this is a pointer to JNI's JNIEnv variable. Any callback from Java into C++ will have this passed in as it's first parameter.
jContext	this is a jobject referring to your app/service/receiver/ provider's Context. JUCE needs this for many of it's internal functions.

◆ isBackgroundThreadRunning()

bool juce::MidiOutput::isBackgroundThreadRunning ( ) const

inlinenoexcept

Returns true if the background thread used to send blocks of data is running.

See also: startBackgroundThread, stopBackgroundThread

◆ isRealtime()

bool juce::Thread::isRealtime ( ) const

inherited

Returns true if this Thread represents a realtime thread.

◆ isThreadRunning()

bool juce::Thread::isThreadRunning ( ) const

inherited

Returns true if the thread is currently active.

Referenced by juce::detail::MessageThread::isRunning().

◆ killThread()

void juce::Thread::killThread ( )

privateinherited

◆ launch() [1/2]

static bool juce::Thread::launch	(	Priority	priority,
		std::function< void()>	functionToRun
	)

staticinherited

Invokes a lambda or function on its own thread with a custom priority.

This will spin up a Thread object which calls the function and then exits. Bear in mind that starting and stopping a thread can be a fairly heavyweight operation, so you might prefer to use a ThreadPool if you're kicking off a lot of short background tasks.

Also note that using an anonymous thread makes it very difficult to interrupt the function when you need to stop it, e.g. when your app quits. So it's up to you to deal with situations where the function may fail to stop in time.

Parameters

priority	The priority the thread is started with.
functionToRun	The lambda to be called from the new Thread.

Returns: true if the thread started successfully, or false if it failed.

◆ launch() [2/2]

static bool juce::Thread::launch ( std::function< void()> functionToRun )

staticinherited

Invokes a lambda or function on its own thread with the default priority.

This will spin up a Thread object which calls the function and then exits. Bear in mind that starting and stopping a thread can be a fairly heavyweight operation, so you might prefer to use a ThreadPool if you're kicking off a lot of short background tasks.

Also note that using an anonymous thread makes it very difficult to interrupt the function when you need to stop it, e.g. when your app quits. So it's up to you to deal with situations where the function may fail to stop in time.

Parameters

functionToRun The lambda to be called from the new Thread.

Returns: true if the thread started successfully, or false if it failed.

See also: launch.

◆ notify()

void juce::Thread::notify ( ) const

inherited

Wakes up the thread.

If the thread has called the wait() method, this will wake it up.

See also: wait

◆ openDevice()

static std::unique_ptr< MidiOutput > juce::MidiOutput::openDevice ( const String & deviceIdentifier )

static

Tries to open one of the midi output devices.

This will return a MidiOutput object if it manages to open it, you can then send messages to this device.

If the device can't be opened, this will return an empty object.

Parameters

deviceIdentifier the ID of the device to open - use the getAvailableDevices() method to find the available devices that can be opened

See also: getDevices

◆ removeListener()

void juce::Thread::removeListener ( Listener * )

inherited

Removes a listener added with addListener.

◆ run()

void juce::MidiOutput::run ( )

overrideprivatevirtual

Must be implemented to perform the thread's actual code.

Remember that the thread must regularly check the threadShouldExit() method whilst running, and if this returns true it should return from the run() method as soon as possible to avoid being forcibly killed.

See also: threadShouldExit, startThread

Implements juce::Thread.

◆ sendBlockOfMessages()

void juce::MidiOutput::sendBlockOfMessages	(	const MidiBuffer &	buffer,
		double	millisecondCounterToStartAt,
		double	samplesPerSecondForBuffer
	)

This lets you supply a block of messages that will be sent out at some point in the future.

The MidiOutput class has an internal thread that can send out timestamped messages - this appends a set of messages to its internal buffer, ready for sending.

This will only work if you've already started the thread with startBackgroundThread().

A time is specified, at which the block of messages should be sent. This time uses the same time base as Time::getMillisecondCounter(), and must be in the future.

The samplesPerSecondForBuffer parameter indicates the number of samples per second used by the MidiBuffer. Each event in a MidiBuffer has a sample position, and the samplesPerSecondForBuffer value is needed to convert this sample position to a real time.

◆ sendBlockOfMessagesNow()

void juce::MidiOutput::sendBlockOfMessagesNow ( const MidiBuffer & buffer )

Sends out a sequence of MIDI messages immediately.

◆ sendMessageNow()

void juce::MidiOutput::sendMessageNow ( const MidiMessage & message )

Sends out a MIDI message immediately.

◆ setAffinityMask()

void juce::Thread::setAffinityMask ( uint32 affinityMask )

inherited

Sets the affinity mask for the thread.

This will only have an effect next time the thread is started - i.e. if the thread is already running when called, it'll have no effect.

See also: setCurrentThreadAffinityMask

◆ setCurrentThreadAffinityMask()

void juce::Thread::setCurrentThreadAffinityMask ( uint32 affinityMask )

staticinherited

Changes the affinity mask for the caller thread.

This will change the affinity mask for the thread that calls this static method.

See also: setAffinityMask

References juce::Thread::affinityMask, jassertfalse, JUCE_BEGIN_IGNORE_WARNINGS_GCC_LIKE, and JUCE_END_IGNORE_WARNINGS_GCC_LIKE.

◆ setCurrentThreadName()

void juce::Thread::setCurrentThreadName ( const String & newThreadName )

staticinherited

Changes the name of the caller thread.

Different OSes may place different length or content limits on this name.

References JUCE_AUTORELEASEPOOL.

◆ setName()

void juce::MidiOutput::setName ( const String & newName )

inlinenoexcept

Sets a custom name for the device.

◆ setPriority()

bool juce::Thread::setPriority ( Priority newPriority )

protectedinherited

Attempts to set the priority for this thread.

Returns true if the new priority was set successfully, false if not.

This can only be called from the target thread. Doing so from another thread will cause an assert.

Parameters

newPriority The new priority to be applied to the thread. Note: This has no effect on Linux platforms, subsequent calls to 'getPriority' will return this value.

See also: Priority

◆ signalThreadShouldExit()

void juce::Thread::signalThreadShouldExit ( )

inherited

Sets a flag to tell the thread it should stop.

Calling this means that the threadShouldExit() method will then return true. The thread should be regularly checking this to see whether it should exit.

If your thread makes use of wait(), you might want to call notify() after calling this method, to interrupt any waits that might be in progress, and allow it to reach a point where it can exit.

See also: threadShouldExit, waitForThreadToExit

Referenced by juce::detail::MessageThread::stop().

◆ sleep()

void juce::Thread::sleep ( int milliseconds )

staticinherited

Suspends the execution of the current thread until the specified timeout period has elapsed (note that this may not be exact).

The timeout period must not be negative and whilst sleeping the thread cannot be woken up so it should only be used for short periods of time and when other methods such as using a WaitableEvent or CriticalSection are not possible.

Referenced by juce::OpenGLContext::NativeContext::getNativeWindowFromSurfaceHolder(), juce::detail::MessageThread::run(), and juce::OpenGLContext::NativeContext::swapBuffers().

◆ startBackgroundThread()

void juce::MidiOutput::startBackgroundThread ( )

Starts up a background thread so that the device can send blocks of data.

Call this to get the device ready, before using sendBlockOfMessages().

◆ startRealtimeThread()

bool juce::Thread::startRealtimeThread ( const RealtimeOptions & options )

inherited

Starts the thread with realtime performance characteristics on platforms that support it.

You cannot change the options of a running realtime thread, nor switch a non-realtime thread to a realtime thread. To make these changes you must first stop the thread and then restart with different options.

Parameters

options Realtime options the thread should be created with.

See also: startThread, RealtimeOptions

◆ startThread() [1/2]

bool juce::Thread::startThread ( )

inherited

Attempts to start a new thread with default ('Priority::normal') priority.

This will cause the thread's run() method to be called by a new thread. If this thread is already running, startThread() won't do anything.

If a thread cannot be created with the requested priority, this will return false and Thread::run() will not be called. An exception to this is the Android platform, which always starts a thread and attempts to upgrade the thread after creation.

Returns: true if the thread started successfully. false if it was unsuccessful.

See also: stopThread

Referenced by juce::detail::MessageThread::start().

◆ startThread() [2/2]

bool juce::Thread::startThread ( Priority newPriority )

inherited

Attempts to start a new thread with a given priority.

This will cause the thread's run() method to be called by a new thread. If this thread is already running, startThread() won't do anything.

If a thread cannot be created with the requested priority, this will return false and Thread::run() will not be called. An exception to this is the Android platform, which always starts a thread and attempts to upgrade the thread after creation.

Parameters

newPriority Priority the thread should be assigned. This parameter is ignored on Linux.

Returns: true if the thread started successfully, false if it was unsuccesful.

See also: startThread, setPriority, startRealtimeThread

◆ startThreadInternal()

bool juce::Thread::startThreadInternal ( Priority )

privateinherited

◆ stopBackgroundThread()

void juce::MidiOutput::stopBackgroundThread ( )

Stops the background thread, and clears any pending midi events.

See also: startBackgroundThread

◆ stopThread()

bool juce::Thread::stopThread ( int timeOutMilliseconds )

inherited

Attempts to stop the thread running.

This method will cause the threadShouldExit() method to return true and call notify() in case the thread is currently waiting.

Hopefully the thread will then respond to this by exiting cleanly, and the stopThread method will wait for a given time-period for this to happen.

If the thread is stuck and fails to respond after the timeout, it gets forcibly killed, which is a very bad thing to happen, as it could still be holding locks, etc. which are needed by other parts of your program.

Parameters

timeOutMilliseconds The number of milliseconds to wait for the thread to finish before killing it by force. A negative value in here will wait forever.

Returns: true if the thread was cleanly stopped before the timeout, or false if it had to be killed by force.

Referenced by juce::detail::MessageThread::stop().

◆ threadEntryPoint()

void juce::Thread::threadEntryPoint ( )

privateinherited

◆ threadShouldExit()

bool juce::Thread::threadShouldExit ( ) const

inherited

Checks whether the thread has been told to stop running.

Threads need to check this regularly, and if it returns true, they should return from their run() method at the first possible opportunity.

See also: signalThreadShouldExit, currentThreadShouldExit

Referenced by juce::detail::MessageThread::run().

◆ wait()

bool juce::Thread::wait ( double timeOutMilliseconds ) const

inherited

Suspends the execution of this thread until either the specified timeout period has elapsed, or another thread calls the notify() method to wake it up.

A negative timeout value means that the method will wait indefinitely.

Returns: true if the event has been signalled, false if the timeout expires.

◆ waitForThreadToExit()

bool juce::Thread::waitForThreadToExit ( int timeOutMilliseconds ) const

inherited

Waits for the thread to stop.

This will wait until isThreadRunning() is false or until a timeout expires.

Parameters

timeOutMilliseconds the time to wait, in milliseconds. If this value is less than zero, it will wait forever.

Returns: true if the thread exits, or false if the timeout expires first.

◆ yield()

void juce::Thread::yield ( )

staticinherited

Yields the current thread's CPU time-slot and allows a new thread to run.

If there are no other threads of equal or higher priority currently running then this will return immediately and the current thread will continue to run.
