Class SimpleParam<T>

java.lang.Object

org.omnifaces.component.SimpleParam<T>

Type Parameters:

T - The type of the value.

All Implemented Interfaces:

ValueHolder, ParamHolder<T>

public class SimpleParam<T>
extends Object
implements ParamHolder<T>

This class provides a basic and default implementation of the ParamHolder interface. Ultimately, this class can be used as a simple key-value pair holder (parameter name-value) which uses an explicit/implicit JSF converter to convert the object value to string.

Since:

1.7
