public final class RGBA
extends java.lang.Object
The hashCode() method in this class uses the values of the public fields to compute the hash value. When storing instances of the class in hashed collections, do not modify these fields after the object has been inserted.
Application code does not need to explicitly release the
resources managed by each instance when those instances are no longer
required, and thus no dispose()
method is provided.
