Enclosing interface:

MethodAttributeAppender

public static enum MethodAttributeAppender.ForInstrumentedMethod
extends Enum<MethodAttributeAppender.ForInstrumentedMethod>
implements MethodAttributeAppender, MethodAttributeAppender.Factory

Implementation of a method attribute appender that writes all annotations of the instrumented method to the method that is being created. This includes method and parameter annotations.

Enum Constant Detail

EXCLUDING_RECEIVER

public static final MethodAttributeAppender.ForInstrumentedMethod EXCLUDING_RECEIVER

Appends all annotations of the instrumented method but not the annotations of the method's receiver type if such a type exists.

INCLUDING_RECEIVER

public static final MethodAttributeAppender.ForInstrumentedMethod INCLUDING_RECEIVER

Appends all annotations of the instrumented method including the annotations of the method's receiver type if such a type exists.

If a method is overridden, the annotations can be misplaced if the overriding class does not expose a similar structure to the method that declared the method, i.e. the same amount of type variables and similar owner types. If this is not the case, type annotations are appended as if the overridden method was declared by the original type. This does not corrupt the resulting class file but it might result in type annotations not being visible via core reflection. This might however confuse other tools that parse the resulting class file manually.

Method Detail

values

public static MethodAttributeAppender.ForInstrumentedMethod[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (MethodAttributeAppender.ForInstrumentedMethod c : MethodAttributeAppender.ForInstrumentedMethod.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static MethodAttributeAppender.ForInstrumentedMethod valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

make

public MethodAttributeAppender make(TypeDescription typeDescription)

Description copied from interface: MethodAttributeAppender.Factory

Returns a method attribute appender that is applicable for a given type description.

Specified by:

make in interface MethodAttributeAppender.Factory

Parameters:

typeDescription - The type for which a method attribute appender is to be applied for.

Returns:

The method attribute appender which should be applied for the given type.

apply

public void apply(MethodVisitor methodVisitor,
                  MethodDescription methodDescription,
                  AnnotationValueFilter annotationValueFilter)

Description copied from interface: MethodAttributeAppender

Applies this attribute appender to a given method visitor.

Specified by:

apply in interface MethodAttributeAppender

Parameters:

methodVisitor - The method visitor to which the attributes that are represented by this attribute appender are written to.

methodDescription - The description of the method for which the given method visitor creates an instrumentation for.

annotationValueFilter - The annotation value filter to apply when the annotations are written.

appendReceiver

protected abstract AnnotationAppender appendReceiver(AnnotationAppender annotationAppender,
                                                     AnnotationValueFilter annotationValueFilter,
                                                     MethodDescription methodDescription)

Appends the annotations of the instrumented method's receiver type if this is enabled and such a type exists.

Parameters:

annotationAppender - The annotation appender to use.

annotationValueFilter - The annotation value filter to apply when the annotations are written.

methodDescription - The instrumented method.

Returns:

The resulting annotation appender.

toString
