Member Function Documentation

virtual UnicodeFunctor* UnicodeFunctor::clone (  void    )  const [pure virtual]

Return a copy of this object. All UnicodeFunctor objects have to support cloning in order to allow classes using UnicodeFunctor to implement cloning. Draft: This API has been introduced in ICU 2.4. It is still in draft state and may be modified in a future release. Reimplemented in UnicodeSet.

virtual UClassID UnicodeFunctor::getDynamicClassID (  void    )  const [pure virtual]

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)&fgClassID; } static char fgClassID; Subclasses that do not implement this method will have a dynamic class ID of UnicodeFunctor::getStatisClassID(). Returns: The class ID for this object. All objects of a given class have the same class ID. Objects of other classes have different class IDs. Draft: This API has been introduced in ICU 2.4. It is still in draft state and may be modified in a future release. Reimplemented from UObject. Reimplemented in UnicodeFilter, and UnicodeSet.

virtual void UnicodeFunctor::setData (  const TransliterationRuleData *    )  [pure virtual]

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. Internal: For internal use only. Reimplemented in UnicodeFilter.

virtual UnicodeMatcher* UnicodeFunctor::toMatcher (    )  const [virtual]

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. Draft: This API has been introduced in ICU 2.4. It is still in draft state and may be modified in a future release. Reimplemented in UnicodeFilter.

virtual UnicodeReplacer* UnicodeFunctor::toReplacer (    )  const [virtual]

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. Draft: This API has been introduced in ICU 2.4. It is still in draft state and may be modified in a future release.
