Detailed Description

@brief A source of characters for an ANTLR lexer.

This is an abstract class that must be implemented by a subclass.

Member Function Documentation

def rve_interface_gen.antlr3.streams.CharStream.getCharPositionInLine

(

self

)

The index of the character relative to the beginning of the line 0..n-1

Reimplemented in rve_interface_gen.antlr3.streams.ANTLRStringStream.

Definition at line 231 of file streams.py.

def rve_interface_gen.antlr3.streams.CharStream.getLine

(

self

)

ANTLR tracks the line information automatically

Reimplemented in rve_interface_gen.antlr3.streams.ANTLRStringStream.

Definition at line 217 of file streams.py.

def rve_interface_gen.antlr3.streams.CharStream.LT	(		self,
			i
	)

Get the ith character of lookahead.  This is the same usually as
LA(i).  This will be used for labels in the generated
lexer code.  I'd prefer to return a char here type-wise, but it's
probably better to be 32-bit clean and be consistent with LA.

Reimplemented in rve_interface_gen.antlr3.streams.ANTLRStringStream.

Definition at line 206 of file streams.py.

def rve_interface_gen.antlr3.streams.CharStream.setCharPositionInLine	(		self,
			pos
	)

Reimplemented in rve_interface_gen.antlr3.streams.ANTLRStringStream.

Definition at line 239 of file streams.py.

def rve_interface_gen.antlr3.streams.CharStream.setLine	(		self,
			line
	)

Because this stream can rewind, we need to be able to reset the line

Reimplemented in rve_interface_gen.antlr3.streams.ANTLRStringStream.

Definition at line 223 of file streams.py.

def rve_interface_gen.antlr3.streams.CharStream.substring	(		self,
			start,
			stop
	)

For infinite streams, you don't need this; primarily I'm providing
a useful interface for action code.  Just make sure actions don't
use this on streams that don't support it.
