Class TransformerProperty<R,W>

java.lang.Object

com.google.code.validationframework.base.property.AbstractReadableProperty<R>

com.google.code.validationframework.base.property.AbstractReadableWritableProperty<R,W>

com.google.code.validationframework.base.property.TransformerProperty<R,W>

Type Parameters:

R - Type of data that can be read from this property.

W - Type of data that can be written from this property.

All Implemented Interfaces:

com.google.code.validationframework.api.property.ReadableProperty<R>, com.google.code.validationframework.api.property.ReadableWritableProperty<R,W>, com.google.code.validationframework.api.property.WritableProperty<W>

public class TransformerProperty<R,W>
extends com.google.code.validationframework.base.property.AbstractReadableWritableProperty<R,W>

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

Listeners will only be notified if the new output value resulting from a new input value 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.
