This connection may either be "in series" +* (where the first Mapping is used to transform the coordinates of +* each point and the second mapping is then applied to the +* result), or "in parallel" (where one Mapping transforms the +* earlier coordinates for each point and the second Mapping +* simultaneously transforms the later coordinates). +* +* Since a CmpMap is itself a Mapping, it can be used as a +* component in forming further CmpMaps. Mappings of arbitrary +* complexity may be built from simple individual Mappings in this +* way. + +* Inheritance: +* The CmpMap class inherits from the Mapping class. + +* Attributes Over-Ridden: +* None. + +* New Attributes Defined: +* None. + +* Methods Over-Ridden: +* Public: +* astSimplify +* Simplify a CmpMap. +* +* Protected: +* astMapList +* Decompose a CmpMap into a sequence of simpler Mappings. +* astTransform +* Transform a set of points. + +* New Methods Defined: +* Public: +* None. +* +* Protected: +* None. + +* Other Class Functions: +* Public: +* astIsACmpMap +* Test class membership. +* astCmpMap +* Create a CmpMap. +* +* Protected: +* astCheckCmpMap +* Validate class membership. +* astInitCmpMap +* Initialise a CmpMap. +* astInitCmpMapVtab +* Initialise the virtual function table for the CmpMap class. +* astLoadCmpMap +* Load a CmpMap. + +* Macros: +* None. + +* Type Definitions: +* Public: +* AstCmpMap +* CmpMap object type. +* +* Protected: +* AstCmpMapVtab +* CmpMap virtual function table type. + +* Feature Test Macros: +* astCLASS +* If the astCLASS macro is undefined, only public symbols are +* made available, otherwise protected symbols (for use in other +* class implementations) are defined.
