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 interfaceStackManipulation
- 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 interfaceStackManipulation
- 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 interfaceMethodInvocation.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 interfaceMethodInvocation.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(java.lang.String methodName, TypeDescription returnType, java.util.List<? extends TypeDescription> methodType, java.util.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 interfaceMethodInvocation.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 aMethodHandle
.- Specified by:
onHandle
in interfaceMethodInvocation.WithImplicitInvocationTargetType
- Parameters:
type
- The type of invocation.- Returns:
- A stack manipulation that represents a method call of the specified method via a method handle.
