Method Summary | |
void |
adjustBeginLineColumn(int newLine,
int newCol)
Method to adjust line and column numbers for the start of a token. |
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. |
private void |
ExpandBuff(boolean wrapAround)
|
private void |
FillBuff()
|
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 |
getColumn()
Returns the column position of the character last read. |
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). |
java.lang.String |
GetImage()
Returns a string made up of characters from the marked token beginning to the current buffer position. |
int |
getLine()
Returns the line number of the character last read. |
char[] |
GetSuffix(int len)
Returns an array of characters that make up the suffix of length 'len' for the currently matched token. |
char |
readChar()
Returns the next character from the selected input. |
