Reimplemented from acdk::io::AbstractFilterReader.

virtual int acdk::io::TeeReader::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) ``

Returns:
number of bytes readed. may less than input if EOS is reached

Exceptions:

EOF exception, if trying to read behind EOS

Reimplemented from acdk::io::AbstractFilterReader.

virtual int acdk::io::TeeReader::read ( ) [inline, virtual]

read a single byte from stream

Returns:
the byte readed or -1 if EOS.

Exceptions:

EOF exception, if trying to read behind EOS

Reimplemented from acdk::io::AbstractFilterReader.
