Method Summary

Modifier and TypeMethod and Description
public MethodTypeDesc
invocationType()

Implements java.lang.constant.MethodHandleDesc.invocationType.

Returns a MethodTypeDesc describing the invocation type of the method handle described by this nominal descriptor.

public MethodHandle
resolveConstantDesc(MethodHandles.Lookup lookup)

Overrides java.lang.constant.DynamicConstantDesc.resolveConstantDesc.

Implements java.lang.constant.MethodHandleDesc.resolveConstantDesc, java.lang.constant.ConstantDesc.resolveConstantDesc.

Resolves this descriptor reflectively, emulating the resolution behavior of JVMS 5.4.3 and the access control behavior of JVMS 5.4.4.

public String
toString()

Overrides java.lang.constant.DynamicConstantDesc.toString.

Returns a compact textual description of this constant description, including the bootstrap method, the constant name and type, and the static bootstrap arguments.

public MethodTypeDesc invocationType()

Implements java.lang.constant.MethodHandleDesc.invocationType.

Doc from java.lang.constant.MethodHandleDesc.invocationType.

Returns a MethodTypeDesc describing the invocation type of the method handle described by this nominal descriptor. The invocation type describes the full set of stack values that are consumed by the invocation (including the receiver, if any).

Overrides java.lang.constant.DynamicConstantDesc.resolveConstantDesc.

Implements java.lang.constant.MethodHandleDesc.resolveConstantDesc, java.lang.constant.ConstantDesc.resolveConstantDesc.

Doc from java.lang.constant.ConstantDesc.resolveConstantDesc.

Resolves this descriptor reflectively, emulating the resolution behavior of JVMS 5.4.3 and the access control behavior of JVMS 5.4.4. The resolution and access control context is provided by the MethodHandles.Lookup parameter. No caching of the resulting value is performed.
