List of all members.

Public Member Functions

int LT (int i)

Get the ith character of lookahead. This is usually the same 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.

string Substring (int start, int stop)

Properties

int Line [get, set]

The current line in the character stream (ANTLR tracks the line information automatically. To support rewinding character streams, we are able to [re-]set the line.

int CharPositionInLine [get, set]

The index of the character relative to the beginning of the line (0..n-1). To support rewinding character streams, we are able to [re-]set the character position.

int Antlr.Runtime.ICharStream.LT ( int i )

Get the ith character of lookahead. This is usually the same 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.

Implemented in Antlr.Runtime.ANTLRStringStream.

string Antlr.Runtime.ICharStream.Substring	(	int	start,
		int	stop
	)

This primarily a useful interface for action code (just make sure actions don't use this on streams that don't support it). For infinite streams, you don't need this.

Implemented in Antlr.Runtime.ANTLRStringStream.

Property Documentation

int Antlr.Runtime.ICharStream.Line [get, set]

The current line in the character stream (ANTLR tracks the line information automatically. To support rewinding character streams, we are able to [re-]set the line.

Implemented in Antlr.Runtime.ANTLRStringStream.

Definition at line 54 of file ICharStream.cs.

int Antlr.Runtime.ICharStream.CharPositionInLine [get, set]

The index of the character relative to the beginning of the line (0..n-1). To support rewinding character streams, we are able to [re-]set the character position.

Implemented in Antlr.Runtime.ANTLRStringStream.
