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

LexerInputState::LexerInputState ( InputBuffer *  inbuf )

inline

Construct a new LexerInputState

Parameters

inbuf

the InputBuffer to read from. The object is deleted together with the LexerInputState object.

LexerInputState::LexerInputState ( InputBuffer &  inbuf )

inline

Construct a new LexerInputState

Parameters

inbuf

the InputBuffer to read from.

virtual LexerInputState::~LexerInputState ( )

inlinevirtual

LexerInputState::LexerInputState ( const LexerInputState &  )

private

virtual void LexerInputState::initialize ( std::istream &  in, const char *  file = ""  )

inlinevirtual

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.

virtual void LexerInputState::reset ( void  )

inlinevirtual

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

void 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
