Detailed Description

This object contains the data associated with an input stream of characters. Multiple lexers share a single LexerSharedInputState to lex the same input stream.


Constructor & Destructor Documentation

antlr::LexerInputState::LexerInputState ( InputBuffer inbuf) [inline]

Construct a new LexerInputState

Parameters:
inbufthe InputBuffer to read from. The object is deleted together with the LexerInputState object.
antlr::LexerInputState::LexerInputState ( InputBuffer inbuf) [inline]

Construct a new LexerInputState

Parameters:
inbufthe InputBuffer to read from.
antlr::LexerInputState::LexerInputState ( std::istream &  in) [inline]

Construct a new LexerInputState

Parameters:
inan istream to read from.

Member Function Documentation

InputBuffer & antlr::LexerInputState::getInput ( ) [inline]
virtual void antlr::LexerInputState::initialize ( std::istream &  in,
const char *  file = "" 
) [inline, virtual]

Reset the LexerInputState with a specified stream and filename. This method is a hack, dunno what I was thinking when I added it. This should actually be done in a subclass.

Deprecated:
LexerInputState& antlr::LexerInputState::operator= ( const LexerInputState ) [private]
virtual void antlr::LexerInputState::reset ( void  ) [inline, virtual]

Reset the LexerInputState to initial state. The underlying InputBuffer is also reset.

void antlr::LexerInputState::setPosition ( int  line_,
int  column_ 
) [inline]

Set the file position of the SharedLexerInputState.

Parameters:
line_line number to be set
column_column number to be set
