Inheritance diagram for casa::LattRegionHolder:
Part of API
The only purpose of LattRegionHolder is to have a single object for the various kinds of regions. It can hold a LCRegion , and LCSlicer .
It was felt that making an abstract base class LatticeRegion for LCRegion and WCRegion would create undesirable dependencies of module Lattices on module Coordinates. E.g. it would be impossible to have a function toWCRegion. Therefore the container class LattRegionHolder is chosen, from which the container ImageRegion is derived.

| casa::LattRegionHolder::LattRegionHolder | ( | const LCRegion & | ) |
Construct from a region based on lattice coordinates.
| casa::LattRegionHolder::LattRegionHolder | ( | const LCSlicer & | ) |
Construct from a slicer based on lattice coordinates.
| casa::LattRegionHolder::LattRegionHolder | ( | LCRegion * | ) | [explicit] |
Similar constructors as above, but using a pointer.
It takes over the pointer, so the user should not delete the object. It is deleted by the LattRegionHolder destructor.

Construct for the given dimensionality (for derived classes).

Get the region as a pointer to a LCRegion, LCSlicer, or WCRegion.
An exception is thrown if the region is not the correct type. Functions isWCRegion(), etc. can be used to test the type.
