Method Summary | |
---|---|
void |
clear()
Clears the values in this AttributeImpl and resets it to its default value. |
Object |
clone()
Shallow clone. |
void |
copyTo(AttributeImpl target)
Copies the values from this Attribute into the passed-in target attribute. |
boolean |
equals(Object other)
All values used for computation of AttributeImpl.hashCode()
should be checked here for equality. |
int |
hashCode()
Subclasses must implement this method and should compute a hashCode similar to this: |
char[] |
resizeTermBuffer(int newSize)
Grows the termBuffer to at least size newSize, preserving the existing content. |
void |
setTermBuffer(char[] buffer,
int offset,
int length)
Copies the contents of buffer, starting at offset for length characters, into the termBuffer array. |
void |
setTermBuffer(String buffer)
Copies the contents of buffer into the termBuffer array. |
void |
setTermBuffer(String buffer,
int offset,
int length)
Copies the contents of buffer, starting at offset and continuing for length characters, into the termBuffer array. |
void |
setTermLength(int length)
Set number of valid characters (length of the term) in the termBuffer array. |
String |
term()
Returns the Token's term text. |
char[] |
termBuffer()
Returns the internal termBuffer character array which you can then directly alter. |
int |
termLength()
Return number of valid characters (length of the term) in the termBuffer array. |
String |
toString()
The default implementation of this method accesses all declared fields of this object and prints the values in the following syntax: |

public String term()

and termLength()
directly instead. If you really need a
String, use this method, which is nothing more than
a convenience call to new String(token.termBuffer(), 0, token.termLength())
