Constructor Detail

MethodMatchAdapter

protected MethodMatchAdapter(LatentMatcher<? super MethodDescription> matcher)

Creates a new method match adapter.

Parameters:

matcher - The method matcher of this adapter.

Method Detail

intercept

public DynamicType.Builder.MethodDefinition.ReceiverTypeDefinition<U> intercept(Implementation implementation)

Implements the previously defined or matched method by the supplied implementation. A method interception is typically implemented in one of the following ways:

1. If a method is declared by the instrumented type and the type builder creates a subclass or redefinition, any preexisting method is replaced by the given implementation. Any previously defined implementation is lost.
2. If a method is declared by the instrumented type and the type builder creates a rebased version of the instrumented type, the original method is preserved within a private, synthetic method within the instrumented type. The original method therefore remains invokeable and is treated as the direct super method of the new method. When rebasing a type, it therefore becomes possible to invoke a non-virtual method's super method when a preexisting method body is replaced.
3. If a virtual method is inherited from a super type, it is overridden. The overridden method is available for super method invocation.

Parameters:

implementation - The implementation for implementing the previously defined or matched method.

Returns:

A new builder where the previously defined or matched method is implemented by the supplied implementation.

withoutCode

public DynamicType.Builder.MethodDefinition.ReceiverTypeDefinition<U> withoutCode()

Defines the previously defined or matched method not to declare a method body. This implies the method to be abstract unless it was already declared to be native.

Returns:

A new builder where the previously defined or matched method is implemented to be abstract.

defaultValue

public DynamicType.Builder.MethodDefinition.ReceiverTypeDefinition<U> defaultValue(AnnotationValue<?,?> annotationValue)

Defines the previously defined or matched method to return the supplied value as an annotation default value. The value must be supplied in its unloaded state, i.e. enumerations as EnumerationDescription, types as TypeDescription and annotations as AnnotationDescription. For supplying loaded types, use DynamicType.Builder.MethodDefinition.ImplementationDefinition.defaultValue(Object, Class) must be used.

Parameters:

annotationValue - The value to be defined as a default value.

Returns:

A builder where the previously defined or matched method is implemented to return an annotation default value.
