Class to interrogate an MS for metadata. Interrogation happens on demand and resulting metadata are stored for use by subsequent queries if the cache has not exceeded the specified limit. Caching of MS main table columns has been removed because the cache can be swamped by columns for large MSes, meaning that smaller data structures, which are more computationally expensive to create, aren't cached. Also, the column data is usually only needed temporarily to compute smaller data structures, and the column data is not particularly expensive to recreate if necessary. Parallel processing is enabled using openmp.

casacore::MSMetaData::MSMetaData | ( | const MeasurementSet *const & | ms, |

) |
construct an object which stores a pointer to the MS and queries the MS only as necessary.
The MeasurementSet pointer passed in should not go out of scope in the calling code until the caller has finished with this object, or else subsequent method calls on this object will result in a segmentation fault; the pointer is not copied. maxCacheSizeMB
is the maximum cache size in megabytes. <=0 means do not use a cache, in which case, each method call will have to (re)query the MS. It is highly recommended to use a cache of reasonable size for the specified MS if multiple methods are going to be called.

If True, force the subscan properties structure to be cached regardless of the stipulations on the maximum cache.
Normally, the subscan properties structure is small compared to the size of any one column that is necessary to create it, and since creating this structure can be very expensive, especially for large datasets, it is often a good idea to cache it if it will be accessed many times.

The general pattern is that a mutable gets set only once, on demand, when its setter is called for the first time.
If this pattern is broken, defective behavior will occur.
