Class Mod

java.lang.Object
org.codehaus.janino.Mod
public final class Mod extends Object
This class defines constants and convenience methods for the handling of modifiers as defined by the JVM.

Notice: This class should be named IClass.IModifier, but changing the name would break existing client code. Thus it won't be renamed until there's a really good reason to do it (maybe with a major design change).

      An alias for '0' -- no modifiers.
      See Also:

    • PUBLIC

      public static final short PUBLIC
      The flag indicating 'public accessibility' of the modified element. Methods of interfaces are always PUBLIC.

    • SUPER

      public static final short SUPER
      This flag is always set on classes, and never set on any other element. Notice that it has the same value as SYNCHRONIZED, which is OK because SYNCHRONIZED is for methods and SUPER for classes.
      See Also:

    • SYNCHRONIZED

      public static final short SYNCHRONIZED
      This flag is set on SYNCHRONIZED methods. Notice that it has the same value as SUPER, which is OK because SYNCHRONIZED is for methods and SUPER for classes.
