      • evaluate

        public boolean evaluate​(MapEvent<?,​V> event)
        Apply the test to the input argument.
        Specified by:
        evaluate in interface Filter<V>
        Parameters:
        event - the input argument to evaluate
        Returns:
        true if the input argument matches the filter, otherwise false
      • extract

        protected E extract​(V target)
        Extract value from a target object.
        Parameters:
        target - the object to extract the value from

        the extracted value
      • equals

        public boolean equals​(Object o)
        Compare the ValueChangeEventFilter with another object to determine equality.
        Overrides:
        equals in class Object
        Returns:
        true iff this ValueChangeEventFilter and the passed object are equivalent filters
      • hashCode

        public int hashCode()

        Specified by:
        readExternal in interface ExternalizableLite
        Parameters:
        in - the DataInput stream to read data from in order to restore the state of this object
        Throws:
        IOException - if an I/O exception occurs
        NotActiveException - if the object is not in its initial state, and therefore cannot be deserialized into
      • writeExternal
