Field Details

typeDescription

private final TypeDescription typeDescription

The method to be invoked.

methodDescription

private final MethodDescription.InDefinedShape methodDescription

The type on which this method is to be invoked.

Constructor Details

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 Details

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 name,
 TypeDescription returnType,
 List<? extends TypeDescription> methodType,
 List<? extends JavaConstant> 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:

name - 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.
