Detailed Description

Base class of the Incremental Storage Manager

Intended use:

Internal

Review Status

Reviewed By:: UNKNOWN
Date Reviewed:: before2004/08/25
Test programs:: tIncrementalStMan

Prerequisite

Etymology

ISMBase is the base class of the Incremental Storage Manager.

Synopsis

The behaviour of this class is described in IncrementalStMan.

Motivation

The public interface of ISMBase is quite large, because the other internal ISM classes need these functions. To have a class with a minimal interface for the normal user, class IncrementalStMan is derived from it.
IncrementalStMan needs an isA- instead of hasA-relation to be able to bind columns to it in class SetupNewTable.

To Do

Removed AipsIO argument from open and close.

Definition at line 87 of file ISMBase.h.

Constructor & Destructor Documentation

◆ ISMBase() [1/4]

casacore::ISMBase::ISMBase	(	uInt	bucketSize = `0`,
		Bool	checkBucketSize = `True`,
		uInt	cacheSize = `1`
	)

explicit

Create an incremental storage manager without a name.

The bucket size has to be given in bytes and the cache size in buckets. The bucket size is checked or calculated (if 0) as described in IncrementalStMan.h.

◆ ISMBase() [2/4]

casacore::ISMBase::ISMBase	(	const String &	dataManagerName,
		uInt	bucketSize,
		Bool	checkBucketSize,
		uInt	cacheSize
	)

Create an incremental storage manager with the given name.

The bucket size has to be given in bytes and the cache size in buckets. The bucket size is checked or calculated (if 0) as described in IncrementalStMan.h.

◆ ISMBase() [3/4]

casacore::ISMBase::ISMBase	(	const String &	aDataManName,
		const Record &	spec
	)

Create an incremental storage manager with the given name.

The specifications are in the record (as created by dataManagerSpec).

◆ ~ISMBase()

Member Function Documentation

◆ addBucket()

void casacore::ISMBase::addBucket	(	rownr_t	rownr,
