Constructor Detail

Invocation

protected Invocation(MethodDescription.InDefinedShape methodDescription)

Creates an invocation of a given method on its declaring type as an invocation target.

Parameters:

methodDescription - The method to be invoked.

Invocation

protected Invocation(MethodDescription.InDefinedShape methodDescription,
                     TypeDescription typeDescription)

Creates an invocation of a given method on a given invocation target type.

Parameters:

methodDescription - The method to be invoked.

typeDescription - The type on which this method is to be invoked.

Method Detail

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.

virtual

public StackManipulation virtual(TypeDescription invocationTarget)

Transforms this method invocation into a virtual (or interface) method invocation on the given type.

Specified by:

virtual in interface MethodInvocation.WithImplicitInvocationTargetType

Parameters:

invocationTarget - The type on which the method is to be invoked virtually on.

Returns:

A stack manipulation representing this method invocation.

special

public StackManipulation special(TypeDescription invocationTarget)

Transforms this method invocation into a special invocation on the given type.

Specified by:

special in interface MethodInvocation.WithImplicitInvocationTargetType

Parameters:

invocationTarget - The type on which the method is to be invoked specially on.

Returns:

A stack manipulation representing this method invocation.

dynamic

public StackManipulation dynamic(String methodName,
                                 TypeDescription returnType,
                                 List<? extends TypeDescription> methodType,
                                 List<?> arguments)

Invokes the method as a bootstrap method to bind a call site with the given properties. Note that the Java virtual machine currently only knows how to resolve bootstrap methods that link static methods or a constructor.

Specified by:

dynamic in interface MethodInvocation.WithImplicitInvocationTargetType

Parameters:

methodName - The name of the method to be bound.

returnType - The return type of the method to be bound.

methodType - The parameter types of the method to be bound.

arguments - The arguments to be passed to the bootstrap method.

Returns:

A stack manipulation that represents the dynamic method invocation.

onHandle

public StackManipulation onHandle(MethodInvocation.HandleType type)

Invokes the method via a MethodHandle.

Specified by:

onHandle in interface MethodInvocation.WithImplicitInvocationTargetType

Parameters:

type - The type of invocation.

Returns:

A stack manipulation that represents a method call of the specified method via a method handle.
