Class Overview

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 JavaTM Virtual Machine Specification, Second edition tables 4.1, 4.4, 4.5, and 4.7.

Public Methods

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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
