Detailed Description

Read uncompressed bytes from a Gzip-compressed file.

This is basically a wrapper around Zlib's gzFile with correct closing and error checking.

Constructor & Destructor Documentation

GzipFileReader()

byteme::GzipFileReader::GzipFileReader ( const char * path, const GzipFileReaderOptions & options )

inline

Parameters

path	Path to the file.
options	Further options.

Member Function Documentation

available()

std::size_t byteme::GzipFileReader::available ( ) const

inlinevirtual

This method should only be called after load() has been called and returns true. The return value is generally expected to be positive; however, it is possible to return a zero. Note that zero values should not be interpreted as the end of the source, which is strictly only defined by load() returning false.

Returns

Number of available bytes in buffer().

Implements byteme::Reader.

buffer()

const unsigned char * byteme::GzipFileReader::buffer ( ) const

inlinevirtual

This method should only be called after load() has been called and returns true.

Returns

Pointer to the start of an array containing the available bytes. The number of available bytes is provided in available().

Implements byteme::Reader.

load()

bool byteme::GzipFileReader::load ( )

inlinevirtual

Read the next chunk of bytes from the input source. To read the entire source, this function should be called repeatedly until false is returned. After returning false once, the behavior of subsequent calls is undefined.

Returns

Boolean indicating whether the read was successful. If false, it can be assumed that the end of the source was reached.

Implements byteme::Reader.
