Modifier « Modifier « Reflection

The Modifier class provides static methods and constants to decode class and member access modifiers.

Return	Field	Summary
static int	ABSTRACT	The int value representing the abstract modifier.
static int	FINAL	The int value representing the final modifier.
static int	INTERFACE	The int value representing the interface modifier.
static int	NATIVE	The int value representing the native modifier.
static int	PRIVATE	The int value representing the private modifier.
static int	PROTECTED	The int value representing the protected modifier.
static int	PUBLIC	The int value representing the public modifier.
static int	STATIC	The int value representing the static modifier.
static int	STRICT	The int value representing the strictfp modifier.
static int	SYNCHRONIZED	The int value representing the synchronized modifier.
static int	TRANSIENT	The int value representing the transient modifier.
static int	VOLATILE	The int value representing the volatile modifier.

Return	Method	Summary
static boolean	isAbstract(int mod)	Is abstract modifier.
static boolean	isFinal(int mod)	Is final modifier.
static boolean	isInterface(int mod)	Is interface modifier.
static boolean	isNative(int mod)	Is native modifier.
static boolean	isPrivate(int mod)	Is private modifier.
static boolean	isProtected(int mod)	Is protected modifier.
static boolean	isPublic(int mod)	Is public modifier.
static boolean	isStatic(int mod)	Is static modifier.
static boolean	isStrict(int mod)	Is strictfp modifier.
static boolean	isSynchronized(int mod)	Is synchronized modifier.
static boolean	isTransient(int mod)	Is transient modifier.
static boolean	isVolatile(int mod)	Is volatile modifier.
static String	toString(int mod)	Convert modifier int flag to string.

Return true if the integer argument includes the public modifier, false otherwise

java.lang.String class modifier is public
