Modifier (Java Platform SE 6)

This documentation differs from the official API. Jadeite adds extra features to the API including: variable font sizes, constructions examples, placeholders for classes and methods, and auto-generated “See Also” links. Additionally it is missing some items found in standard Javadoc documentation, including: generics type information, “Deprecated” tags and comments, “See Also” links, along with other minor differences. Please send any questions or feedback to bam@cs.cmu.edu.

public class Modifier
extends Object

The Modifier class provides static methods and constants to decode class and member access modifiers. The sets of modifiers are represented as integers with distinct bit positions representing different modifiers. The values for the constants representing the modifiers are taken from The Java^TM Virtual Machine Specification, Second edition tables 4.1, 4.4, 4.5, and 4.7.

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.

Constructor Summary
`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.

public Modifier()

Method Detail

isAbstract

public static boolean isAbstract(int mod)

Return true if the integer argument includes the abstract modifier, false otherwise.

Parameters:: mod - a set of modifiers
Returns:: true if mod includes the abstract modifier; false otherwise.

isFinal

public static boolean isFinal(int mod)

Return true if the integer argument includes the final modifier, false otherwise.

Parameters:: mod - a set of modifiers
Returns:: true if mod includes the final modifier; false otherwise.

isInterface

public static boolean isInterface(int mod)

Return true if the integer argument includes the interface modifier, false otherwise.

Parameters:: mod - a set of modifiers
Returns:: true if mod includes the interface modifier; false otherwise.

isNative

public static boolean isNative(int mod)

Return true if the integer argument includes the native modifier, false otherwise.

Parameters:: mod - a set of modifiers
Returns:: true if mod includes the native modifier; false otherwise.

isPrivate

public static boolean isPrivate(int mod)

Return true if the integer argument includes the private modifier, false otherwise.

Parameters:: mod - a set of modifiers
Returns:: true if mod includes the private modifier; false otherwise.

isProtected

public static boolean isProtected(int mod)

Return true if the integer argument includes the protected modifier, false otherwise.

Parameters:: mod - a set of modifiers
Returns:: true if mod includes the protected modifier; false otherwise.

isPublic

public static boolean isPublic(int mod)

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

Parameters:: mod - a set of modifiers
Returns:: true if mod includes the public modifier; false otherwise.

isStatic

public static boolean isStatic(int mod)

Return true if the integer argument includes the static modifier, false otherwise.

Parameters:: mod - a set of modifiers
Returns:: true if mod includes the static modifier; false otherwise.

isStrict

public static boolean isStrict(int mod)

Return true if the integer argument includes the strictfp modifier, false otherwise.

Parameters:: mod - a set of modifiers
Returns:: true if mod includes the strictfp modifier; false otherwise.

isSynchronized

public static boolean isSynchronized(int mod)

Return true if the integer argument includes the synchronized modifier, false otherwise.

Parameters:: mod - a set of modifiers
Returns:: true if mod includes the synchronized modifier; false otherwise.

isTransient

public static boolean isTransient(int mod)

Return true if the integer argument includes the transient modifier, false otherwise.

Parameters:: mod - a set of modifiers
Returns:: true if mod includes the transient modifier; false otherwise.

isVolatile

public static boolean isVolatile(int mod)

Return true if the integer argument includes the volatile modifier, false otherwise.

Parameters:: mod - a set of modifiers
Returns:: true if mod includes the volatile modifier; false otherwise.

toString

public static String toString(int mod)

Return a string describing the access modifier flags in the specified modifier. For example:

    public final synchronized strictfp

The modifier names are returned in an order consistent with the suggested modifier orderings given in The Java Language Specification, Second Edition sections §8.1.1, §8.3.1, §8.4.3, §8.8.3, and §9.1.1. The full modifier ordering used by this method is:

public protected private abstract static final transient volatile synchronized native strictfp interface

The interface modifier discussed in this class is not a true modifier in the Java language and it appears after all other modifiers listed by this method. This method may return a string of modifiers that are not valid modifiers of a Java entity; in other words, no checking is done on the possible validity of the combination of modifiers represented by the input.

Parameters:: mod - a set of modifiers
Returns:: a string representation of the set of modifiers represented by mod
