addObserver
public void addObserver(ClassObserver o)
- Add observer for this object.
removeObserver
public void removeObserver(ClassObserver o)
- Remove observer for this object.
update
public void update()
- Call notify() method on all observers. This method is not called
automatically whenever the state has changed, but has to be
called by the user after he has finished editing the object.
clone
public java.lang.Object clone()
- Description copied from class:
java.lang.Object
- This method may be called to create a new copy of the
Object. The typical behavior is as follows:
o == o.clone() is falseo.getClass() == o.clone().getClass()
is trueo.equals(o) is true
However, these are not strict requirements, and may
be violated if necessary. Of the three requirements, the
last is the most commonly violated, particularly if the
subclass does not override Object.equals(Object)>Object.equals(Object) 55 .
If the Object you call clone() on does not implement
java.lang.Cloneable (which is a placeholder interface), then
a CloneNotSupportedException is thrown. Notice that
Object does not implement Cloneable; this method exists
as a convenience for subclasses that do.
Object's implementation of clone allocates space for the
new Object using the correct class, without calling any
constructors, and then fills in all of the new field values
with the old field values. Thus, it is a shallow copy.
However, subclasses are permitted to make a deep copy.
All array types implement Cloneable, and override
this method as follows (it should never fail):
public Object clone()
{
try
{
super.clone();
}
catch (CloneNotSupportedException e)
{
throw new InternalError(e.getMessage());
}
}
getComparator
public static org.apache.bcel.util.BCELComparator getComparator()
setComparator
public static void setComparator(org.apache.bcel.util.BCELComparator comparator)
equals
public boolean equals(java.lang.Object obj)
- Return value as defined by given BCELComparator strategy.
By default two ClassGen objects are said to be equal when
their class names are equal.
hashCode
public int hashCode()
- Return value as defined by given BCELComparator strategy.
By default return the hashcode of the class name.
