Constructor & Destructor Documentation

◆ LzssReadStream()

ZVision::LzssReadStream::LzssReadStream ( Common::SeekableReadStream *  source)

A class that decompresses LZSS data and implements ReadStream for easy access to the decompiled data.

Parameters
sourceThe source data

Member Function Documentation

◆ eos()

bool ZVision::LzssReadStream::eos ( ) const
overridevirtual

Return true if a read failed because the stream end has been reached.

This flag is cleared by clearErr(). For a SeekableReadStream, the flag is also cleared by a successful seek.

Note
The semantics of any implementation of this method is supposed to match that of ISO C feof(). In particular, in a stream with N bytes, reading exactly N bytes from the start should not set eos; only reading beyond the available data should set it.

Implements Common::ReadStream.

◆ read()

uint32 ZVision::LzssReadStream::read ( void *  dataPtr,
uint32  dataSize 
)
overridevirtual

Read data from the stream.

Subclasses must implement this method. All other read methods are implemented using it.

Note
The semantics of any implementation of this method is supposed to match that of ISO C fread(), in particular where it concerns setting error and end of file/stream flags.
Parameters
dataPtrPointer to a buffer into which the data is read.
dataSizeNumber of bytes to be read.
Returns
The number of bytes that were actually read.

Implements Common::ReadStream.
