Member Data Documentation

contents

VBytes IJS::contents

The entire contents of the file is loaded into this vector.

Referenced by load(), SessionComponentTransfer::run(), and warnings().

jobs

std::vector<const RecJob*> IJS::jobs

Even though this is a vector, we only support a single RecJob pointer per ijs file.

Referenced by load(), summary(), and warnings().

groups

std::vector<const RecGroup*> IJS::groups

The groups stored in this vector may be stored in a different order than what they appear in the ijs file.

When they're parsed, the groups are re-ordered so this vector contains the groups id #1, 2, 3, 4, ... while in the ijs file they sometimes appear out-of-order, such as #2, 3, 4, 1.

Referenced by load(), SessionComponent::paintCell(), summary(), and warnings().

file

File IJS::file

.ijs file

Referenced by PrintJob::copy_to_new_directory(), load(), summary(), and warnings().

number_of_unknown_bytes

size_t IJS::number_of_unknown_bytes

Used to keep track of whether or not there were unrecognized bytes when the .IJS file was loaded.

Referenced by load(), and warnings().
