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.

Definition at line 47 of file LexerSharedInputState.hpp.

LexerInputState::LexerInputState ( ANTLR_USE_NAMESPACE(std) istream & in ) [inline]

Construct a new LexerInputState

Parameters:

in

an istream to read from.

Member Function Documentation

virtual void LexerInputState::initialize	(	ANTLR_USE_NAMESPACE(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.
