Detailed Description
EOL Transcoder.
Under some OSs, and in some stream environment (i.e. TELNET streams, HTTP headers etc.), the line terminator is a sequence of characters CR+LF. Falcon strings internal encoding sees '
' (LF) as a line terminator marker. As the transcoders are objects meant to translate the Falcon internal encoding into a text resource under the rules of external encoding, they also provide the facility to translate LF character into a CRLF sequence, and to recognize the CRLF sequence in read to translate it back into a '
' line terminator.
This trancoder can be cascaded with other transcoder; the stream used by this transcoder may be another transcoder storing output to files.

Member Function Documentation
| virtual FalconData* Falcon::TranscoderEOL::clone | ( | ) | const [virtual] |
Clones the stream.
This version returns 0 and sets error to unsupported; subclasses must properly clone the stream.
Reimplemented from Falcon::Stream.
| virtual const String Falcon::TranscoderEOL::encoding | ( | ) | const [inline, virtual] |
Returns the character encoding which is managed by this transcoder.
Subclasses must reimplement this to return the name of the supported encoding.
Implements Falcon::Transcoder.
| virtual bool Falcon::TranscoderEOL::get | ( | uint32 & | chr | ) | [virtual] |
Gets next character from the stream.
Subclasses must manage both stateful transcoding and properly popping readahead characters from the buffer.
- Returns:
- true if the character is available, false on stream end or error.
Implements Falcon::Stream.
| virtual bool Falcon::TranscoderEOL::put | ( | uint32 | chr | ) | [virtual] |
Writes a character on the stream.
- Parameters:
-
chr the character to write.
- Returns:
- true success, false on stream error.
Reimplemented from Falcon::Stream.
