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.

Definition at line 32 of file LexerSharedInputState.hpp.
References column, filename, guessing, input, inputResponsible, line, tokenStartColumn, and tokenStartLine.

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

Construct a new LexerInputState.

Parameters:

inbuf the InputBuffer to read from.

Definition at line 47 of file LexerSharedInputState.hpp.
References column, filename, guessing, input, inputResponsible, line, tokenStartColumn, and tokenStartLine.

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

Construct a new LexerInputState.

Parameters:

in an istream to read from.

Member Function Documentation

InputBuffer & LexerInputState::getInput ( ) [inline]

Definition at line 147 of file LexerSharedInputState.hpp.

virtual void 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& LexerInputState::operator= ( const LexerInputState & ) [private]

virtual void LexerInputState::reset ( void ) [inline, virtual]

Reset the LexerInputState to initial state.
The underlying InputBuffer is also reset.
Definition at line 99 of file LexerSharedInputState.hpp.
References column, guessing, input, line, InputBuffer::reset(), tokenStartColumn, and tokenStartLine.

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
