Class ObjectId
ObjectId provides an object identification mechanism which gives each object
a name in the form
<class><Nameindex>.
Each id can be in an unused state which means that only one instance of the
object is in use and a special id is not needed. Certain
Element subclasses use this feature to find
out whether they write the "id" attribute or not.
An
ObjectId instance is typically given to multiple objects.
The second user should then invoke the
init() method to generate the
identification string and bring the id in the 'used' state.
void | init()-
Generates a simple Id by concatenating a class name with a self-increasing
number.

boolean | isUnused()
|
String | toString()- Convert this Object to a human-readable String.

clone, equals, extends Object> getClass, finalize, hashCode, notify, notifyAll, toString, wait, wait, wait |
init
public void init()
Generates a simple Id by concatenating a class name with a self-increasing
number.
toString
public String toString()
Convert this Object to a human-readable String.
There are no limits placed on how long this String
should be or what it should contain. We suggest you
make it as intuitive as possible to be able to place
it into
System.out.println()
and such.
It is typical, but not required, to ensure that this method
never completes abruptly with a
RuntimeException.
This method will be called when performing string
concatenation with this object. If the result is
null, string concatenation will instead
use
"null".
The default implementation returns
getClass().getName() + "@" +
Integer.toHexString(hashCode()).
- toString in interface Object
- the String representing this Object, which may be null
