Description:
The IntraMap class provides a specialised form of
Mapping which encapsulates a
privately-defined coordinate transformation other AST Mapping. This allows you to
create Mappings that perform any conceivable coordinate transformation.
However, an IntraMap is intended for use within a single program or a private suite of
software, where all programs have access to the same coordinate transformation
functions (i.e. can be linked against them). IntraMaps should not normally be stored in
datasets which may be exported for processing by other software, since that software
will not have the necessary transformation functions available, resulting in an
error.
You must register any coordinate transformation functions to be used using astIntraReg
before creating an IntraMap.
Constructor Function
Inheritance
The IntraMap class inherits from the Mapping class.
Attributes
In
addition to those attributes common to all Mappings, every IntraMap also has the
following attributes:
Functions
The IntraMap class does not
define any new functions beyond those which are applicable to all Mappings.
