Interface If<V,P>

All Known Implementing Classes:
Always, IfDefault, IfEmpty, IfEmptyString, IfFalse, IfNotDefault, IfNotEmpty, IfNotNull, IfNotZero, IfNull, IfTrue, IfZero, PojoIf, ValueIf
public interface If<V,P>

A simple interface that defines a condition test for a field value or whole entity. For example, you could have a class that tests against null values called IfNull. This interface is used by the @IgnoreSave, @Index, and @Unindex annotations.

The matching engine will call both methods; if either return true the condition is considered true.

All implementations of this interface will be created with ObjectifyFactory.construct(). If the implementation also implements the InitializeIf interface, the init() method will be called immediately after construction.
