Destructor.
|
|
Return a copy of this object. All UnicodeFunctor objects have to support cloning in order to allow classes using UnicodeFunctor to implement cloning.
Implemented in UnicodeSet. |
|
Returns a unique class ID polymorphically. This method is to implement a simple version of RTTI, since not all C++ compilers support genuine RTTI. Polymorphic operator==() and clone() methods call this method. Concrete subclasses of UnicodeFunctor should use the macro UOBJECT_DEFINE_RTTI_IMPLEMENTATION from uobject.h to provide definitios getStaticClassID and getDynamicClassID.
Implements UObject. Implemented in UnicodeFilter, and UnicodeSet. |
|
Return the class ID for this class. This is useful only for comparing to a return value from getDynamicClassID().
Reimplemented in UnicodeFilter, and UnicodeSet. |
|
Set the data object associated with this functor. The data object provides context for functor-to-standin mapping. This method is required when assigning a functor to a different data object. This function MAY GO AWAY later if the architecture is changed to pass data object pointers through the API.
Implemented in UnicodeFilter. |
|
Cast 'this' to a UnicodeMatcher* pointer and return the pointer, or null if this is not a UnicodeMatcher*. Subclasses that mix in UnicodeMatcher as a base class must override this. This protocol is required because a pointer to a UnicodeFunctor cannot be cast to a pointer to a UnicodeMatcher, since UnicodeMatcher is a mixin that does not derive from UnicodeFunctor.
Reimplemented in UnicodeFilter. |
|
Cast 'this' to a UnicodeReplacer* pointer and return the pointer, or null if this is not a UnicodeReplacer*. Subclasses that mix in UnicodeReplacer as a base class must override this. This protocol is required because a pointer to a UnicodeFunctor cannot be cast to a pointer to a UnicodeReplacer, since UnicodeReplacer is a mixin that does not derive from UnicodeFunctor.
