public class Modifier
extends Object

Modifiers defines access flags that modify classes or their members.

Field Summary

static int	ABSTRACT Modifier flag for abstract classes or methods classes.
static int	FINAL Modifier flag for final (non-overwritable, non redefinable or non extendible) members or classes.
static int	INTERFACE Modifier flag for interface classes.
static int	NATIVE Modifier flag for native (non-Java) methods and constructors.
static int	PRIVATE Modifier flag for private visibility.
static int	PROTECTED Modifier flag for protected visibility.
static int	PUBLIC Modifier flag for public visibility.
static int	STATIC Modifier flag for static (non-instance) members.
static int	STRICT Modifier flag for strict floating point semantic methods or constructors.
static int	SYNCHRONIZED Modifier flag for synchronized methods and constructors.
static int	TRANSIENT Modifier flag for transient (non-serialized) fields.
static int	VOLATILE Modifier flag for volatile fields.

Constructor Summary

Modifier()
Pretty useless constructor, this class does not declare any instance methods.

static boolean	isPrivate(int mod) Test if given modifiers include the PRIVATE flag.
static boolean	isProtected(int mod) Test if given modifiers include the PROTECTED flag.
static boolean	isPublic(int mod) Test if given modifiers include the PUBLIC flag.
static boolean	isStatic(int mod) Test if given modifiers include the STATIC flag.
static boolean	isStrict(int mod) Test if given modifiers include the STRICT flag.
static boolean	isSynchronized(int mod) Test if given modifiers include the SYNCHRONIZED flag.
static boolean	isTransient(int mod) Test if given modifiers include the TRANSIENT flag.
static boolean	isVolatile(int mod) Test if given modifiers include the VOLATILE flag.
static String	toString(int mod) Create a space separated string representation of the given modifiers in the order public, protected, private, abstract, static, final, transient, volatile, synchronized, native, strictfp, interface.
