method.R
- The type of the return type of thecall
method.
- All Known Implementing Classes:
MapValueFactory
,PropertyValueFactory
,TreeItemPropertyValueFactory
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface Callback<P,R>
The Callback interface is designed to allow for a common, reusable interface
to exist for defining APIs that requires a call back in certain situations.
Callback is defined with two generic parameters: the first parameter
specifies the type of the object passed in to the call
method,
with the second parameter specifying the return type of the method.
