Class TransformerProperty<I,O>

java.lang.Object

com.google.code.validationframework.base.binding.AbstractReadableProperty<O>

com.google.code.validationframework.base.binding.TransformerProperty<I,O>

Type Parameters:

I -

O -

All Implemented Interfaces:

ReadableProperty<O>, WritableProperty<I>

public class TransformerProperty<I,O>
extends AbstractReadableProperty<O>
implements WritableProperty<I>

Implementation of a readable and writable property whose output is the result of the transformation of the input.

Slaved properties will only be updated if the new value set on this property differs from the previous one.

Note that binding can be bi-directional. Infinite recursion will be prevented.

Finally note that this class is not thread-safe.
