Interface PropertyAccessor<T>

All Known Implementing Classes:

ArrayPropertyAccessor, JavaBeanPropertyAccessor, ListPropertyAccessor, MapPropertyAccessor

public interface PropertyAccessor<T>

Interface which is implemented by classes capable of acting as accessors for certain types of classes. Currently this is tied very tightly to the NodeType enum. Each PropertyAccessor must be able to store and retrieve values from the target type.

Since:

Stripes 1.4
