virtual int acdk::vfile::InflaterReader::available ( ) [virtual]

returns the number of bytes available in this stream before blocking Some Reader always return 0

virtual void acdk::vfile::InflaterReader::close ( ) [virtual]

closes this Reader.

Note: Some Reader must be closed explicitaly Note: Reader implementation must be avare from closing a reader more than one

virtual int acdk::vfile::InflaterReader::read	(	byte *	buffer,
		int	offset,
		int	len
	)	`[virtual]`

virtual int acdk::vfile::InflaterReader::read	(	IN(RbyteArray)	buffer,
		int	offset = 0,
		int	len = -1
	)	`[inline, virtual]`

read the len bytes into buffer at offset of the buffer

Parameters:

buffer	where to write the bytes
offset	offset to write into buffer
len	how many bytes to read. if == -1 read into many bytes, that fits into buffer (buffer->length() - offset) ``
