Package org.apache.jackrabbit.oak.api

Class Type<T>

java.lang.Object

org.apache.jackrabbit.oak.api.Type<T>

Type Parameters:

T -

All Implemented Interfaces:

Comparable<Type<?>>

public final class Type<T>
extends Object
implements Comparable<Type<?>>

Instances of this class map Java types to property types. Passing an instance of this class to PropertyState.getValue(Type) determines the return type of that method.
