Constructor & Destructor Documentation
◆ ~UnicodeFunctor()
|
virtual |
Destructor.
- Stable:
- ICU 2.4
Member Function Documentation
◆ clone()
|
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.
- Stable:
- ICU 2.4
Implemented in icu::UnicodeSet, and icu::UnicodeFilter.
◆ getDynamicClassID()
|
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 should use the macro UOBJECT_DEFINE_RTTI_IMPLEMENTATION from uobject.h to provide definitios getStaticClassID and getDynamicClassID.
- 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.
- Stable:
- ICU 2.4
Reimplemented from icu::UObject.
Implemented in icu::UnicodeSet.
◆ getStaticClassID()
|
static |
Return the class ID for this class.
This is useful only for comparing to a return value from getDynamicClassID().
- Returns
- The class ID for all objects of this class.
- Stable:
- ICU 2.0
◆ setData()
|
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:
- Do not use. This API is for internal use only. ICU 2.1
Implemented in icu::UnicodeFilter.
◆ toMatcher()
|
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.
- Stable:
- ICU 2.4
Reimplemented in icu::UnicodeFilter.
◆ toReplacer()
|
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.
- Stable:
- ICU 2.4
