Constructor Detail

Redirection

protected Redirection(TypeDescription forwardingType,
                      MethodDescription sourceMethod,
                      Assigner assigner,
                      boolean serializableProxy)

Creates a new redirection.

Parameters:

forwardingType - The type that declares the method for forwarding a method invocation.

sourceMethod - The method that is to be forwarded.

assigner - The assigner to use.

serializableProxy - Determines if the generated proxy should be Serializable.

Method Detail

extractFields

private static java.util.LinkedHashMap<java.lang.String,TypeDescription> extractFields(MethodDescription methodDescription)

Extracts all parameters of a method to fields.

Parameters:

methodDescription - The method to extract the parameters from.

Returns:

A linked hash map of field names to the types of these fields representing all parameters of the given method.

fieldName

private static java.lang.String fieldName(int index)

Creates a new field name.

Parameters:

index - The index of the field.

Returns:

The field name that corresponds to the index.

make

public DynamicType make(java.lang.String auxiliaryTypeName,
                        ClassFileVersion classFileVersion,
                        MethodAccessorFactory methodAccessorFactory)

Creates a new auxiliary type.

Specified by:

make in interface AuxiliaryType

Parameters:

auxiliaryTypeName - The fully qualified binary name for this auxiliary type. The type should be in the same package than the instrumented type this auxiliary type is providing services to in order to allow package-private access.

classFileVersion - The class file version the auxiliary class should be written in.

methodAccessorFactory - A factory for accessor methods.

Returns:

A dynamically created type representing this auxiliary type.

isValid

public boolean isValid()

Determines if this stack manipulation is valid.

Specified by:

isValid in interface StackManipulation

Returns:

If false, this manipulation cannot be applied and should throw an exception.

apply

public StackManipulation.Size apply(org.objectweb.asm.MethodVisitor methodVisitor,
                                    Implementation.Context implementationContext)

Applies the stack manipulation that is described by this instance.

Specified by:

apply in interface StackManipulation

Parameters:

methodVisitor - The method visitor used to write the method implementation to.

implementationContext - The context of the current implementation.

Returns:

The changes to the size of the operand stack that are implied by this stack manipulation.
