UnicodeFunctor
is an abstract base class for objects that perform match and/or replace operations on Unicode strings.
|
Return a copy of this object. All UnicodeFunctor objects have to support cloning in order to allow classes using UnicodeFunctor to implement cloning. ICU 2.4 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 that wish clients to be able to identify them should implement getDynamicClassID() and also a static method and data member:
static UClassID getStaticClassID() { return (UClassID) } static char fgClassID; Subclasses that do not implement this method will have a dynamic class ID of UnicodeFunctor::getStatisClassID().
Implements UObject.
Implemented 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. For internal use only. ICU 2.1 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. ICU 2.4 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. ICU 2.4 |
