Parameters

a class object representing the desired result type T

target: MethodHandle

a direct method handle to crack into symbolic reference components

Returns

Object

a reference to the method, constructor, or field object

Attributes: RegisterAttribute JavaTypeParametersAttribute

Remarks

Performs an unchecked "crack" of a direct method handle. The result is as if the user had obtained a lookup object capable enough to crack the target method handle, called java.lang.invoke.MethodHandles.Lookup#revealDirect Lookup.revealDirect on the target to obtain its symbolic reference, and then called java.lang.invoke.MethodHandleInfo#reflectAs MethodHandleInfo.reflectAs to resolve the symbolic reference to a member.

If there is a security manager, its checkPermission method is called with a ReflectPermission("suppressAccessChecks") permission.
