org.glassfish.rmic.tools.util.ModifierFilter
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.

Field Details

PACKAGE
public static final long PACKAGEPackage 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_ACCESSAll 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.- See Also:

ModifierFilter
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.

Method Details
-
checkModifier

-
checkMember
Filter a MemberDefinition.- Parameters:
field
- A MemberDefinition- Returns:
- Whether the modifier of the field passes this filter.
- See Also:
-
