Member Function Documentation

void Deflator::Flush ( bool completeFlush, int propagation = -1 ) [virtual]

process everything in internal buffers and output them. throws exception if completeFlush == true and it's not possible to flush everything Reimplemented from BufferedTransformation. Definition at line 440 of file zdeflate.cpp.

unsigned int Deflator::GetDeflateLevel ( ) const [inline]

Definition at line 61 of file zdeflate.h.

unsigned int Deflator::GetLog2WindowSize ( ) const [inline]

Definition at line 62 of file zdeflate.h.

void Deflator::MessageEnd ( int propagation = -1 ) [virtual]

mark end of an input segment, message, or packet. propagation != 0 means pass on the signal to attached BufferedTransformation objects, with propagation decremented at each step until it reaches 0. -1 means unlimited propagation. Reimplemented from BufferedTransformation. Definition at line 450 of file zdeflate.cpp.

void Deflator::Put ( const byte * str, unsigned int length ) [virtual]

input multiple bytes. Reimplemented from BufferedTransformation. Definition at line 428 of file zdeflate.cpp.

void Deflator::Put ( byte inByte ) [inline, virtual]

input a byte for processing. Reimplemented from BufferedTransformation. Definition at line 64 of file zdeflate.h.

void Deflator::SetDeflateLevel ( unsigned int deflateLevel )

Definition at line 251 of file zdeflate.cpp.
