This facility is useful when the number of +* coordinates is being increased, as it allows fixed values to be +* assigned to the new coordinates. + +* Inheritance: +* The PermMap class inherits from the Mapping class. + +* Attributes Over-Ridden: +* None. + +* New Attributes Defined: +* None. + +* Methods Over-Ridden: +* Public: +* None. +* +* Protected: +* astTransform +* Transform a set of points. + +* New Methods Defined: +* Public: +* None. +* +* Protected: +* astGetConstants +* Obtain a copy of the constants array +* astGetInPerm +* Obtain a copy of the input permutation array +* astGetOutPerm +* Obtain a copy of the output permutation array + +* Other Class Functions: +* Public: +* astIsAPermMap +* Test class membership. +* astPermMap +* Create a PermMap. +* +* Protected: +* astCheckPermMap +* Validate class membership. +* astInitPermMap +* Initialise a PermMap. +* astInitPermMapVtab +* Initialise the virtual function table for the PermMap class. +* astLoadPermMap +* Load a PermMap. + +* Macros: +* None. + +* Type Definitions: +* Public: +* AstPermMap +* PermMap object type. +* +* Protected: +* AstPermMapVtab +* PermMap 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.
