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. - Since:

kind
DirectMethodHandleDesc.Kind kind()Returns thekind
of the method handle described by this nominal descriptor.- Returns:
- the
DirectMethodHandleDesc.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 aClassDesc
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 byMethodHandleDesc.of(Kind, ClassDesc, String, String)
.- Returns:
- the lookup descriptor string
