Interface DirectMethodHandleDesc

All Superinterfaces:
ConstantDesc, MethodHandleDesc

public interface DirectMethodHandleDesc extends MethodHandleDesc
A nominal descriptor for a direct MethodHandle. A DirectMethodHandleDesc corresponds to a Constant_MethodHandle_info entry in the constant pool of a classfile.
API Note:
In the future, if the Java language permits, DirectMethodHandleDesc may become a sealed interface, which would prohibit subclassing except by explicitly permitted types. Non-platform classes should not implement DirectMethodHandleDesc directly.

  • Method Details

    • kind

      Returns the kind of the method handle described by this nominal descriptor.
      Returns:
      the DirectMethodHandleDesc.Kind
    • refKind

      int refKind()
      Returns the refKind of the method handle described by this nominal reference, as defined by MethodHandleInfo.
      Returns:
      the reference kind
    • isOwnerInterface

      boolean isOwnerInterface()
      Indicates if the method is declared by an interface
      Returns:
      true if the method is declared by an interface
    • owner

      ClassDesc owner()
      Returns a ClassDesc describing the class declaring the method or field described by this nominal descriptor.
      Returns:
      the class declaring the method or field
    • methodName

      String methodName()
      Returns the name of the method or field described by this nominal descriptor. For constructors, returns the reserved name "<init>".
      Returns:
      the name of the method or field
    • lookupDescriptor

      String lookupDescriptor()
      Returns the lookup descriptor of the method handle described by this descriptor, after adjusting for the invocation mode. This will correspond to either a method type descriptor string (for methods and constructors), or a field descriptor string (for field access method handles). The lookup descriptor string is in the same format as accepted by MethodHandleDesc.of(Kind, ClassDesc, String, String).
      Returns:
      the lookup descriptor string
