BaseDataBinding

protected BaseDataBinding(java.lang.Class<?> baseType)

Create a databinding with the base java type whose name will be used as the name of the databinding

Parameters:

baseType - The base java class or interface representing the databinding, for example, org.w3c.dom.Node

BaseDataBinding

protected BaseDataBinding(java.lang.String name,
                          java.lang.Class<?> baseType)

Create a databinding with the name and base java type

Parameters:

name - The name of the databinding

baseType - The base java class or interface representing the databinding, for example, org.w3c.dom.Node

Method Detail

introspect

public boolean introspect(DataType type,
                          Operation operation)
