Scanner

public interface Lexer

The lexical analyzer maps an input stream consisting of ASCII characters and Unicode escapes into a token sequence.

This is NOT part of any supported API. If you write code that depends on this, you do so at your own risk. This code and its internal interfaces are subject to change or deletion without notice.

Method Summary

Modifier and Type	Method and Description
int	errPos() Return the position where a lexical error occurred;
void	errPos(int pos) Set the position where a lexical error occurred;
Position.LineMap	getLineMap() Build a map for translating between line numbers and positions in the input.
void	nextToken() Consume the next token.
Tokens.Token	prevToken() Return the last character position of the previous token.
Tokens.Token	split() Splits the current token in two and return the first (splitted) token.
Tokens.Token	token() Return current token.
Tokens.Token	token(int lookahead) Return token with given lookahead.

Method Detail

nextToken

void nextToken()

Consume the next token.

token

Tokens.Token token()

Return current token.

token

Tokens.Token token(int lookahead)

Return token with given lookahead.

prevToken

Tokens.Token prevToken()

Return the last character position of the previous token.

split

Tokens.Token split()

Splits the current token in two and return the first (splitted) token. For instance '<<<' is split into two tokens '<' and '<<' respectively, and the latter is returned.

errPos

int errPos()

Return the position where a lexical error occurred;

errPos

void errPos(int pos)

Set the position where a lexical error occurred;

getLineMap

Position.LineMap getLineMap()

Build a map for translating between line numbers and positions in the input.

Returns:

a LineMap
