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() [1/3]

antlr::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.

LexerInputState() [2/3]

antlr::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() [3/3]

antlr::LexerInputState::LexerInputState ( std ::istream & in )

inline

Construct a new LexerInputState.

Parameters

in	an istream to read from.

Member Function Documentation

getInput()

InputBuffer & antlr::LexerInputState::getInput ( )

inline

Definition at line 144 of file LexerSharedInputState.hpp.

initialize()

virtual void antlr::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.

Deprecated

Definition at line 80 of file LexerSharedInputState.hpp.

reset()

virtual void antlr::LexerInputState::reset ( void )

inlinevirtual

Reset the LexerInputState to initial state.

The underlying InputBuffer is also reset.

Definition at line 99 of file LexerSharedInputState.hpp.

setPosition()

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

Definition at line 113 of file LexerSharedInputState.hpp.
