version:
1.1 |
| Constructor Summary | |
| public | StringScanner(String stringToScan)
Initialize the new instance with the string that should be scanned. |
| Method Summary | |
| public boolean | atEnd()
Returns true, if the scanner has reached the end and a further
invocation of nextChar() would return the END_REACHED character. | | public boolean | endNotReached(char character)
Returns true, if the given character does not indicate that the
end of the scanned string si reached. | | public boolean | endReached(char character)
Returns true, if the given character indicates that the end of the
scanned string is reached. | | public int | getPosition()
| | public boolean | hasNext()
Returns true, if the scanner has not yet reached the end. | | protected int | length()
| | public void | markPosition()
| | public char | nextChar()
Returns the character at the current position and increments the
position afterwards by 1. | | public char | nextNoneWhitespaceChar()
Returns the next character that is no whitespace and leaves the position
pointer one character after the returned one. | | public char | peek()
Returns the character at the current position without changing the
position, that is subsequent calls to this method return always the
same character. | | public void | restorePosition()
| | protected void | setPosition(int pos)
| | public void | skip(int count)
Moves the position pointer count characters. | | public String | toString()
|
| END_REACHED | | final public static char END_REACHED(Code) | | |
| buffer | | protected char[] buffer(Code) | | |
| length | | protected int length(Code) | | |
| pos_marker | | protected int pos_marker(Code) | | |
| position | | protected int position(Code) | | |
| StringScanner | | public StringScanner(String stringToScan)(Code) | | Initialize the new instance with the string that should be scanned.
Parameters:
stringToScan - |
| atEnd | | public boolean atEnd()(Code) | | Returns true, if the scanner has reached the end and a further
invocation of nextChar() would return the END_REACHED character.
|
| endNotReached | | public boolean endNotReached(char character)(Code) | | Returns true, if the given character does not indicate that the
end of the scanned string si reached.
Parameters:
character - |
| endReached | | public boolean endReached(char character)(Code) | | Returns true, if the given character indicates that the end of the
scanned string is reached.
Parameters:
character - |
| getPosition | | public int getPosition()(Code) | | Returns the current position in the string
|
| hasNext | | public boolean hasNext()(Code) | | Returns true, if the scanner has not yet reached the end.
|
| length | | protected int length()(Code) | | |
| markPosition | | public void markPosition()(Code) | | Remembers the current position for later use with restorePosition()
|
| nextChar | | public char nextChar()(Code) | | Returns the character at the current position and increments the
position afterwards by 1.
|
| nextNoneWhitespaceChar | | public char nextNoneWhitespaceChar()(Code) | | Returns the next character that is no whitespace and leaves the position
pointer one character after the returned one.
|
| peek | | public char peek()(Code) | | Returns the character at the current position without changing the
position, that is subsequent calls to this method return always the
same character.
|
| restorePosition | | public void restorePosition()(Code) | | Restores the position to the value of the latest markPosition() call
|
| setPosition | | protected void setPosition(int pos)(Code) | | |
| skip | | public void skip(int count)(Code) | | Moves the position pointer count characters. positive values move
forwards, negative backwards. The position never becomes negative !
Parameters:
count - |
| toString | | public String toString()(Code) | | Returns the string the scanner was initialized with
