getChar()

virtual int ipe::DataSource::getChar ( )

pure virtual

Get one more character, or EOF.

Referenced by ipe::A85Source::getChar(), ipe::Base64Source::getChar(), ipe::XmlParser::getChar(), and ipe::PdfFile::parse().

length()

int DataSource::length ( ) const

virtual

Return length of input stream in characters.

Returns -1 if the stream is not seekable. Calling this function will invalidate the current position.

setPosition()

void DataSource::setPosition ( int  pos )

virtual

Set position in stream.

Does nothing if the stream is not seekable.

Reimplemented in ipe::BufferSource, and ipe::FileSource.

Referenced by ipe::PdfFile::parse().

position()

int DataSource::position ( ) const

virtual

Return position in stream.

Returns -1 if the stream is not seekable.
