Types

type AccessFlags 

type AccessFlags uint16

AccessFlags is a mask of flags used to denote access permissions to and properties of this class or interface.

The interpretation of each flag, when set, is specified below: 

ACC_PUBLIC      0x0001  Declared public; may be accessed from outside its package.
ACC_FINAL       0x0010  Declared final; no subclasses allowed.
ACC_SUPER       0x0020  Treat superclass methods specially when invoked by the invokespecial instruction.
ACC_INTERFACE   0x0200  Is an interface, not a class.
ACC_ABSTRACT    0x0400  Declared abstract; must not be instantiated.
ACC_SYNTHETIC   0x1000  Declared synthetic; not present in the source code.
ACC_ANNOTATION  0x2000  Declared as an annotation type.
ACC_ENUM        0x4000  Declared as an enum type.
ACC_MODULE      0x8000  Is a module, not a class or interface.
