Class Overview

A class whose instances are filters over Modifier bits. Filtering is done by returning boolean values. Classes, methods and fields can be filtered, or filtering can be done directly on modifier bits. WARNING: The contents of this source file are not part of any supported API. Code that depends on them does so at its own risk: they are subject to change or removal without notice.

Inherited Methods

From class java.lang.reflect.Modifier

static boolean	isAbstract(int mod) Return `true` if the integer argument includes the `abstract` modifier, `false` otherwise.
static boolean	isFinal(int mod) Return `true` if the integer argument includes the `final` modifier, `false` otherwise.
static boolean	isInterface(int mod) Return `true` if the integer argument includes the `interface` modifier, `false` otherwise.
static boolean	isNative(int mod) Return `true` if the integer argument includes the `native` modifier, `false` otherwise.
static boolean	isPrivate(int mod) Return `true` if the integer argument includes the `private` modifier, `false` otherwise.
static boolean	isProtected(int mod) Return `true` if the integer argument includes the `protected` modifier, `false` otherwise.
static boolean	isPublic(int mod) Return `true` if the integer argument includes the `public` modifier, `false` otherwise.
static boolean	isStatic(int mod) Return `true` if the integer argument includes the `static` modifier, `false` otherwise.
static boolean	isStrict(int mod) Return `true` if the integer argument includes the `strictfp` modifier, `false` otherwise.
static boolean	isSynchronized(int mod) Return `true` if the integer argument includes the `synchronized` modifier, `false` otherwise.
static boolean	isTransient(int mod) Return `true` if the integer argument includes the `transient` modifier, `false` otherwise.
static boolean	isVolatile(int mod) Return `true` if the integer argument includes the `volatile` modifier, `false` otherwise.
static String	toString(int mod) Return a string describing the access modifier flags in the specified modifier.

From class java.lang.Object

Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
void	finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
final Class<?>	getClass() Returns the runtime class of this `Object`.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

Constants

public static final long ALL_ACCESS

All access modifiers. A short-hand set of modifier bits that can be used in the constructors of this class to specify all access modifiers, Same as PRIVATE | PROTECTED | PUBLIC | PACKAGE.

Constant Value: -9223372036854775801 (0x8000000000000007)

public static final long PACKAGE

Package private access. A "pseudo-" modifier bit that can be used in the constructors of this class to specify package private access. This is needed since there is no Modifier.PACKAGE.

Constant Value: -9223372036854775808 (0x8000000000000000)

Public Constructors

public ModifierFilter (long oneOf)

Constructor - Specify a filter.

Parameters

oneOf	If zero, everything passes the filter. If non-zero, at least one of the specified bits must be on in the modifier bits to pass the filter.

public ModifierFilter (long oneOf, long must, long cannot)

Constructor - Specify a filter. For example, the filter below will only pass synchronized methods that are private or package private access and are not native or static.

 ModifierFilter(  Modifier.PRIVATE | ModifierFilter.PACKAGE,
                  Modifier.SYNCHRONIZED,
                  Modifier.NATIVE | Modifier.STATIC)

Each of the three arguments must either be zero or the or'ed combination of the bits specified in the class Modifier or this class. During filtering, these values are compared against the modifier bits as follows:

Parameters

oneOf	If zero, ignore this argument. If non-zero, at least one of the bits must be on.
must	All bits specified must be on.
cannot	None of the bits specified can be on.

Public Methods

public boolean checkClass (ClassDefinition cdef)

Filter a ClassDefinition.

Parameters

cdef	A ClassDefinition

Returns

Whether the modifier of the class passes this filter.

public boolean checkMember (MemberDefinition field)

Filter a MemberDefinition.

Parameters

field	A MemberDefinition

Returns

Whether the modifier of the field passes this filter.

public boolean checkModifier (int modifierBits)

Filter on modifier bits.

Parameters

modifierBits	Bits as specified in the Modifier class

Returns

Whether the modifierBits pass this filter.
