public class ModifierFilter extends Modifier
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.

    • PACKAGE

      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.
      See Also:
    • ALL_ACCESS

      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.

      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.
    • ModifierFilter

      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.
