Interface for data objects that support being frozen into immutable representations.
Freeze a volatile representation into an immutable representation.
Check to see if this object is valid for use.
Freeze a volatile representation into an immutable representation. Objects returned from this call are safe to cache.
Note that the output of
freeze may not be identical to the parent object, but should
be equal. In other words:
Freezable f1 = new Freezable(); Freezable f2 = f1.freeze(); f1 == f2 may not be true. f1.equals(f2) will be true.
Check to see if this object is valid for use. If the object is still volatile, this method
will indicate whether or not the object can be safely used. The output of a call to
freeze() will always be valid.
