Modifier and Type | Method and Description |
---|---|
void |
backup(int amount)
Backs up the input stream by amount steps.
|
char |
BeginToken()
Returns the next character that marks the beginning of the next token.
|
void |
Done()
The lexer calls this function to indicate that it is done with the stream
and hence implementations can free any resources held by this class.
|
int |
getBeginColumn()
Returns the column number of the first character for current token (being
matched after the last call to BeginTOken).
|
int |
getBeginLine()
Returns the line number of the first character for current token (being
matched after the last call to BeginTOken).
|
int |
getBeginOffset() |
int |
getColumn()
Deprecated.
|
int |
getEndColumn()
Returns the column number of the last character for current token (being
matched after the last call to BeginTOken).
|
int |
getEndLine()
Returns the line number of the last character for current token (being
matched after the last call to BeginTOken).
|
int |
getEndOffset() |
java.lang.String |
GetImage()
Returns a string made up of characters from the marked token beginning
to the current buffer position.
|
int |
getLine()
Deprecated.
|
