An object that waits for client sockets to connect to a port on this host, and creates InterprocessConnection objects for each one.
More...
#include <juce_InterprocessConnectionServer.h>
An object that waits for client sockets to connect to a port on this host, and creates InterprocessConnection objects for each one.
To use this, create a class derived from it which implements the createConnectionObject() method, so that it creates suitable connection objects for each client that tries to connect.

◆ ThreadID
◆ anonymous enum
Special realtime audio thread priority.
This priority will create a high-priority thread which is best suited for realtime audio processing.
Currently, this priority is identical to priority 9, except when building for Android with OpenSL/Oboe support.
In this case, JUCE will ask OpenSL/Oboe to construct a super high priority thread specifically for realtime audio processing.
Note that this priority can only be set before the thread has started. Switching to this priority, or from this priority to a different priority, is not supported under Android and will assert.
For best performance this thread should yield at regular intervals and not call any blocking APIs.

| bool juce::InterprocessConnectionServer::beginWaitingForSocket |
( |
int |
portNumber, |
|
|
const String & |
bindAddress = String() |
|
) |
| |
Starts an internal thread which listens on the given port number.
While this is running, if another process tries to connect with the InterprocessConnection::connectToSocket() method, this object will call createConnectionObject() to create a connection to that client.
Use stop() to stop the thread running.
- Parameters
-
| portNumber | The port on which the server will receive connections |
| bindAddress | The address on which the server will listen for connections. An empty string indicates that it should listen on all addresses assigned to this machine. |

◆ createConnectionObject()
Creates a suitable connection object for a client process that wants to connect to this one.
This will be called by the listener thread when a client process tries to connect, and must return a new InterprocessConnection object that will then run as this end of the connection.

◆ 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.

◆ getBoundPort()
| int juce::InterprocessConnectionServer::getBoundPort |
( |
| ) |
const |
|
noexcept |
Returns the local port number to which this server is currently bound.
This is useful if you need to know to which port the OS has actually bound your socket when calling beginWaitingForSocket with a port number of zero.
Returns -1 if the function fails.
◆ 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()
◆ getThreadId()
| ThreadID juce::Thread::getThreadId |
( |
| ) |
const |
|
noexceptinherited |
Returns the ID of this thread.
That means the ID of this thread object - not of the thread that's calling the method. This can change when the thread is started and stopped, and will be invalid if the thread's not actually running.
- See also
- getCurrentThreadId
◆ 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"); }
}
- 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. |
◆ isThreadRunning()
| bool juce::Thread::isThreadRunning |
( |
| ) |
const |
|
inherited |
Returns true if the thread is currently active.
◆ killThread()

| ) |
|
|
privateinherited |
◆ launch()
| static void juce::Thread::launch |
( |
std::function< void()> |
functionToRun | ) |
|
|
staticinherited |
Invokes a lambda or function on its own thread.
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.
◆ launchThread()

privateinherited |
◆ notify()
| void juce::Thread::notify |
( |
| ) |
const |
|
inherited |
Wakes up the thread.
If the thread has called the wait() method, this will wake it up.

◆ removeListener()
| void juce::Thread::removeListener |
( |
Listener * |
| ) |
|
|
inherited |
Removes a listener added with addListener.
◆ run()
| void juce::InterprocessConnectionServer::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.

- threadShouldExit, startThread
Implements juce::Thread.
◆ 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.

Changes the thread's priority.
May return false if for some reason the priority can't be changed.
- Parameters
-
| priority | the new priority, in the range 0 (lowest) to 10 (highest). A priority of 5 is normal. |

◆ 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.

◆ startThread() [1/2]
| void juce::Thread::startThread |
( |
| ) |
|
|
inherited |
Starts the thread running.
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.
- See also
- stopThread
◆ startThread() [2/2]
| void juce::Thread::startThread |
( |
int |
priority | ) |
|
|
inherited |
Starts the thread with a given priority.
Launches the thread with a given priority, where 0 = lowest, 10 = highest. If the thread is already running, its priority will be changed.
- See also
- startThread, setPriority, realtimeAudioPriority
◆ stop()
| void juce::InterprocessConnectionServer::stop |
( |
| ) |
|
◆ 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.

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
◆ wait()
| bool juce::Thread::wait |
( |
int |
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.
