Class AbstractLexer.DefaultLexerToken

java.lang.Object
  oracle.javatools.parser.AbstractLexer.DefaultLexerToken

All Implemented Interfaces:

LexerToken

Enclosing class:

AbstractLexer

protected static class AbstractLexer.DefaultLexerToken

extends java.lang.Object

implements LexerToken

The DefaultLexerToken just implements a basic LexerToken which stores a token and start/end offsets.

Field Summary

protected int	endOffset The ending offset in the text buffer of this token.
protected int	startOffset The starting offset in the text buffer of this token.
protected int	token The token that was found.

Constructor Summary

protected

AbstractLexer.DefaultLexerToken()

Method Summary

int	getEndOffset() Fetches the end offset of the token (offset relative to the original ReadTextBuffer being lexed.
int	getStartOffset() Fetches the start offset of the token (offset relative to the original ReadTextBuffer being lexed.
int	getToken() Fetches the (language-specific) token represented by this LexerToken.
void	setEndOffset(int end) Sets the end offset for this token.
void	setStartOffset(int start) Sets the starting offset for this token.
void	setToken(int token) Set the token of this object.

Field Detail

token

protected int token

The token that was found.

startOffset

protected int startOffset

The starting offset in the text buffer of this token.

endOffset

protected int endOffset

The ending offset in the text buffer of this token.

protected AbstractLexer.DefaultLexerToken()

Method Detail

getToken

public int getToken()

Fetches the (language-specific) token represented by this LexerToken. You must refer to the language-specific Lexer that was responsible for filling this LexerToken instance to interpret the token.

Specified by:

getToken in interface LexerToken

Returns:

the lexer token

setToken

public void setToken(int token)

Set the token of this object.

Parameters:

token - the token to set

getStartOffset

public int getStartOffset()

Fetches the start offset of the token (offset relative to the original ReadTextBuffer being lexed. Note that the start offset is inclusive (compare to end offset which is exclusive), to match the behavior in the String class.

Specified by:

getStartOffset in interface LexerToken

Returns:

the starting offset

setStartOffset

public void setStartOffset(int start)

Sets the starting offset for this token.

Parameters:

start - the starting offset

getEndOffset

public int getEndOffset()

Fetches the end offset of the token (offset relative to the original ReadTextBuffer being lexed. Note that the end offset is exclusive (similar to end offsets in the String class.)

Specified by:

getEndOffset in interface LexerToken

Returns:

the ending offset

setEndOffset

public void setEndOffset(int end)

Sets the end offset for this token.

Parameters:

end - the ending offset
