Detailed Description
Deflater push stream interface.
Interface implemented by compression classes. The uncompressed and compressed data is pushed onto and pulled from the stream, respectively. push() may be invoked in the initial mode of the deflation stream unless noted otherwise.

Member Function Documentation
◆ atEnd()
|
pure virtual |
Returns true if the end has been reached (no more uncompressed data may be pulled from the stream). This always returns false until pushEnd() has been invoked.
Implemented in BZip2Deflater, and ZLibDeflater.
◆ flush()
|
pure virtual |
Flushes any uncompressed data onto the stream. The stream has been flushed when pull() returns 0. One or more invocations of pull() is required. push() may only be invoked hereafter.
Reimplemented from PushInterface.
Implemented in BZip2Deflater, and ZLibDeflater.
