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.

isPublic
public static boolean isPublic(int mod)
Return true if the integer argument includes thepublic modifier, false otherwise.
Parameters:
mod - a set of modifiers
Returns:
true if mod includes thepublic modifier; false otherwise.
isPrivate
public static boolean isPrivate(int mod)
Return true if the integer argument includes theprivate modifier, false otherwise.
Parameters:
mod - a set of modifiers
Returns:
true if mod includes theprivate modifier; false otherwise.
isProtected
public static boolean isProtected(int mod)
Return true if the integer argument includes theprotected modifier, false otherwise.
Parameters:
mod - a set of modifiers
Returns:
true if mod includes theprotected modifier; false otherwise.
isStatic
public static boolean isStatic(int mod)
Return true if the integer argument includes thestatic modifier, false otherwise.
Parameters:
mod - a set of modifiers
Returns:
true if mod includes thestatic modifier; false otherwise.
isFinal
public static boolean isFinal(int mod)
Return true if the integer argument includes thefinal modifier, false otherwise.
Parameters:
mod - a set of modifiers
Returns:
true if mod includes thefinal modifier; false otherwise.
isSynchronized
public static boolean isSynchronized(int mod)
Return true if the integer argument includes thesynchronized modifier, false otherwise.
Parameters:
mod - a set of modifiers
Returns:
true if mod includes thesynchronized modifier; false otherwise.
isVolatile
public static boolean isVolatile(int mod)
Return true if the integer argument includes thevolatile modifier, false otherwise.
Parameters:
mod - a set of modifiers
Returns:
true if mod includes thevolatile modifier; false otherwise.
isTransient
public static boolean isTransient(int mod)
Return true if the integer argument includes thetransient modifier, false otherwise.
Parameters:
mod - a set of modifiers
Returns:
true if mod includes thetransient modifier; false otherwise.
isNative
public static boolean isNative(int mod)
Return true if the integer argument includes thenative modifier, false otherwise.
Parameters:
mod - a set of modifiers
Returns:
true if mod includes thenative modifier; false otherwise.
isInterface
public static boolean isInterface(int mod)
Return true if the integer argument includes theinterface modifier, false otherwise.
Parameters:
mod - a set of modifiers
Returns:
true if mod includes theinterface modifier; false otherwise.
isAbstract
public static boolean isAbstract(int mod)
Return true if the integer argument includes theabstract modifier, false otherwise.
Parameters:
mod - a set of modifiers
Returns:
true if mod includes theabstract modifier; false otherwise.
isStrict
public static boolean isStrict(int mod)
Return true if the integer argument includes thestrictfp modifier, false otherwise.
Parameters:
mod - a set of modifiers
Returns:
true if mod includes thestrictfp 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
