| com.sun.tools.javac.parser.Lexer
All known Subclasses: com.sun.tools.javac.parser.Scanner,
| Lexer | | public interface Lexer (Code) | | The lexical analyzer maps an input stream consisting of ASCII
characters and Unicode escapes into a token sequence.
This is NOT part of any API supported by Sun Microsystems.
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

| Method Summary | |
| boolean | deprecatedFlag()
Has a @deprecated been encountered in last doc comment?
This needs to be reset by client with resetDeprecatedFlag. | | String | docComment()
Returns the documentation string of the current token. | | int | endPos()
Return the last character position of the current token. | | int | errPos()
| | void | errPos(int pos)
| | LineMap | getLineMap()
Build a map for translating between line numbers and
positions in the input. | | char[] | getRawCharacters()
Returns a copy of the input buffer, up to its inputLength. | | char[] | getRawCharacters(int beginIndex, int endIndex)
Returns a copy of a character array subset of the input buffer. | | Name | name()
Return the name of an identifier or token for the current token. | | void | nextToken()
Read token. | | int | pos()
| | int | prevEndPos()
Return the last character position of the previous token. | | int | radix()
Return the radix of a numeric literal token. | | void | resetDeprecatedFlag()
| | String | stringVal()
The value of a literal token, recorded as a string. | | Token | token()
Return the current token, set by nextToken(). | | void | token(Token token)
Sets the current token. |
| deprecatedFlag | | boolean deprecatedFlag()(Code) | | Has a @deprecated been encountered in last doc comment?
This needs to be reset by client with resetDeprecatedFlag.
|
| docComment | | String docComment()(Code) | | Returns the documentation string of the current token.
|
| endPos | | int endPos()(Code) | | Return the last character position of the current token.
|
| errPos | | int errPos()(Code) | | Return the position where a lexical error occurred;
|
| errPos | | void errPos(int pos)(Code) | | Set the position where a lexical error occurred;
|
| getLineMap | | LineMap getLineMap()(Code) | | Build a map for translating between line numbers and
positions in the input.
a LineMap |
| getRawCharacters | | char[] getRawCharacters()(Code) | | Returns a copy of the input buffer, up to its inputLength.
Unicode escape sequences are not translated.
|
| getRawCharacters | | char[] getRawCharacters(int beginIndex, int endIndex)(Code) | | Returns a copy of a character array subset of the input buffer.
The returned array begins at the beginIndex and
extends to the character at index endIndex - 1.
Thus the length of the substring is endIndex-beginIndex.
This behavior is like
String.substring(beginIndex, endIndex).
Unicode escape sequences are not translated.
Parameters:
beginIndex - the beginning index, inclusive.
Parameters:
endIndex - the ending index, exclusive.
throws:
IndexOutOfBounds - if either offset is outside of thearray bounds |
| name | | Name name()(Code) | | Return the name of an identifier or token for the current token.
|
| nextToken | | void nextToken()(Code) | | Read token.
|
| pos | | int pos()(Code) | | Return the current token's position: a 0-based
offset from beginning of the raw input stream
(before unicode translation)
|
| prevEndPos | | int prevEndPos()(Code) | | Return the last character position of the previous token.
|
| radix | | int radix()(Code) | | Return the radix of a numeric literal token.
|
| resetDeprecatedFlag | | void resetDeprecatedFlag()(Code) | | |
| stringVal | | String stringVal()(Code) | | The value of a literal token, recorded as a string.
For integers, leading 0x and 'l' suffixes are suppressed.
|
| token | | Token token()(Code) | | Return the current token, set by nextToken().
|
| token | | void token(Token token)(Code) | | Sets the current token.
