Annotation Type DefaultCall

@Documented
@Retention(RUNTIME)
@Target(PARAMETER)
public @interface DefaultCall

A parameter with this annotation is assigned a proxy for invoking a default method that fits the intercepted method. If no suitable default method for the intercepted method can be identified, the target method with the annotated parameter is considered to be unbindable.

Optional Element Summary

Optional Elements

Modifier and Type	Optional Element	Description
boolean	nullIfImpossible	Assigns null to the parameter if it is impossible to invoke the super method or a possible dominant default method, if permitted.
boolean	serializableProxy	Determines if the generated proxy should be Serializable.
java.lang.Class<?>	targetType	If this parameter is not explicitly set, a parameter with the DefaultCall is only bound to a source method if this source method directly represents an unambiguous, invokable default method.

Element Detail

targetType

java.lang.Class<?> targetType

If this parameter is not explicitly set, a parameter with the DefaultCall is only bound to a source method if this source method directly represents an unambiguous, invokable default method. On the other hand, if a method is not defined unambiguously by an interface, not setting this parameter will exclude the target method with the annotated parameter from a binding to the source method.

If this parameter is however set to an explicit interface type, a default method is always invoked on this given type as long as this type defines a method with a compatible signature. If this is not the case, the target method with the annotated parameter is not longer considered as a possible binding candidate of a source method.

Returns:

The target interface that a default method invocation is to be defined upon. If no such explicit target is set, this parameter should not be defined as the predefined void type encodes an implicit resolution.

Default:

void.class

serializableProxy

boolean serializableProxy

Determines if the generated proxy should be Serializable.

Returns:

true if the generated proxy should be Serializable.

Default:

false

nullIfImpossible

boolean nullIfImpossible

Assigns null to the parameter if it is impossible to invoke the super method or a possible dominant default method, if permitted.

Returns:

true if a null constant should be assigned to this parameter in case that a legal binding is impossible.

Default:

false
