com.sun.tools.javac.parser

public Interface Lexer

Known Direct Implementers: com.sun.tools.javac.parser.Scanner, com.sun.tools.javac.parser.VirtualParser.VirtualScanner
Imports: java.util.Queue, com.sun.tools.javac.parser.Tokens.*, com.sun.tools.javac.util.Position.LineMap

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.

public int	errPos() Return the position where a lexical error occurred;
public void	errPos(int pos) Set the position where a lexical error occurred;
public Queue<Tokens.Comment>	getDocComments() Returns a queue for the documentation comments encountered in a compilation unit.
public Position.LineMap	Returns: a LineMap getLineMap() Build a map for translating between line numbers and positions in the input.
public void	nextToken() Consume the next token.
public Tokens.Token	prevToken() Return the last character position of the previous token.

Method Detail

errPos	back to summary
public int errPos() Return the position where a lexical error occurred;

errPos	back to summary
public void errPos(int pos) Set the position where a lexical error occurred;

getDocComments	back to summary
public Queue<Tokens.Comment> getDocComments() Returns a queue for the documentation comments encountered in a compilation unit. Comments may be added to this queue by the implementation; clients may remove them from the queue as they are analyzed. Note all comments may also be associated with the following token.

getLineMap

back to summary

public Position.LineMap getLineMap()

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

Returns:Position.LineMap: a LineMap

nextToken	back to summary
public void nextToken() Consume the next token.

prevToken	back to summary
public Tokens.Token prevToken() Return the last character position of the previous token.

setPrevToken	back to summary
public void setPrevToken(Tokens.Token prevToken) Sets the previous token.

split	back to summary
public Tokens.Token split() Splits the current token in two and return the first (split) token. For instance '<<<' is split into two tokens '<' and '<<' respectively, and the latter is returned.

token	back to summary
public Tokens.Token token() Return current token.

token	back to summary
public Tokens.Token token(int lookahead) Return token with given lookahead.
