Member Function Documentation

virtual int acdk::io::CharToByteReader::available ( ) [inline, virtual]

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

Reimplemented from acdk::io::Reader.

int acdk::io::CharToByteReader::read ( byte * buffer,

int offset,

int len

) [inline, virtual]

See also:
other read(RbyteArray, int, int)

Reimplemented from acdk::io::AbstractReader.

int acdk::io::CharToByteReader::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::AbstractReader.

virtual int acdk::io::CharToByteReader::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::AbstractReader.

virtual void acdk::io::CharToByteReader::reset ( ) [inline, virtual]

if mark is set, set stream to mark point otherwise to begin of this stream.

Implements acdk::io::AbstractReader.

virtual jlong acdk::io::CharToByteReader::seek ( SeekPos seekrel,

jlong seekpos

) [inline, virtual]

Set stream position in this Reader to given position.

Returns:
the absolute position in this stream

Reimplemented from acdk::io::AbstractReader.

virtual jlong acdk::io::CharToByteReader::skip ( jlong n ) [inline, virtual]

Move forwart into the stream.

Returns:
how many bytes skipped. May less then input, in case EOS is reached

Reimplemented from acdk::io::AbstractReader.
