POJO - is the generic type of the Pojo to access.

VALUE - is the generic type of the POJOs property to access.

All Known Implementing Classes:

AbstractUiWidgetAbstractDataTable.LazyPropertyAccessor, PojoPathPropertyAccessor

public interface PropertyAccessor<POJO,VALUE>

This is the interface for an accessor to a specific property of a typed object. It allows to get and set the property abstracting from the way how to do this.
Generic implementations can be based on reflection (e.g. using PojoPathNavigator). However, for environments such as GWT where no reflection is available implementations for each property can be provided either hand-written or generated.

Since:

3.0.0
