Class AbstractEffectiveStatement<A,D extends DeclaredStatement<A>>

java.lang.Object

org.opendaylight.yangtools.yang.parser.rfc7950.stmt.AbstractEffectiveStatement<A,D>

Type Parameters:

A - Argument type (Void if statement does not have argument.)

D - Class representing declared version of this statement.

All Implemented Interfaces:

EffectiveStatement<A,D>, ModelStatement<A>

Direct Known Subclasses:

AbstractDeclaredEffectiveStatement, EffectiveStatementBase

@Beta
public abstract class AbstractEffectiveStatement<A,D extends DeclaredStatement<A>>
extends Object
implements EffectiveStatement<A,D>

Baseline stateless implementation of an EffectiveStatement. This class adds a few default implementations and namespace dispatch, but does not actually force any state on its subclasses. This approach is different from EffectiveStatementBase in that it adds requirements for an implementation, but it leaves it up to the final class to provide object layout.

This finds immense value in catering the common case, for example effective statements which can, but typically do not, contain substatements.
