Method Details

kind

DirectMethodHandleDesc.Kind 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
