Field Details

targetType

private final TypeDescription targetType

The generically resolved return type of the method.

invocation

private final MethodInvocation.WithImplicitInvocationTargetType invocation

The invocation of the method in its defined shape.

Constructor Details

OfGenericMethod

protected OfGenericMethod(TypeDescription targetType,
 MethodInvocation.WithImplicitInvocationTargetType invocation)

Creates a generic method invocation.

Parameters:

targetType - The generically resolved return type of the method.

invocation - The invocation of the method in its defined shape.

Method Details

of

protected static MethodInvocation.WithImplicitInvocationTargetType of(MethodDescription methodDescription,
 MethodInvocation.WithImplicitInvocationTargetType invocation)

Creates a generic access dispatcher for a given method.

Parameters:

methodDescription - The generically resolved return type of the method.

invocation - The invocation of the method in its defined shape.

Returns:

A method access dispatcher for the given method.

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<? 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:

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.

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.
