Detailed Description

Base class for a column in a plain table

Prerequisite

Etymology

PlainColumn represents any column in a plain table. A plain table is a regular table, i.e. not a table like a RefTable which is a view on a plain table.

Synopsis

Abstract base class for all types of columns in a plain table. It implements the common functionality for all columns in a plain table. Furthermore it defines some virtual functions (on top of the virtual functions defined in BaseColumn) which are specific for plain columns.

◆ autoReleaseLock()

void casacore::PlainColumn::autoReleaseLock ( ) const

inlineprotected

Inspect the auto lock when the inspection interval has expired and release it when another process needs the lock.

Definition at line 197 of file PlainColumn.h.

References casacore::ColumnSet::autoReleaseLock(), and colSetPtr_p.

◆ bind()

virtual void casacore::PlainColumn::bind ( DataManager * )

virtual

Bind the column to a data manager.

◆ checkReadLock()

void casacore::PlainColumn::checkReadLock ( Bool wait ) const

inlineprotected

Lock the table before reading or writing.

If manual or permanent locking is in effect, it checks if the table is locked.

Definition at line 193 of file PlainColumn.h.

References casacore::ColumnSet::checkReadLock(), and colSetPtr_p.

◆ checkValueLength() [1/3]

void casacore::PlainColumn::checkValueLength ( const Array< String > * value ) const

void casacore::PlainColumn::checkValueLength ( const String * value ) const

protected

◆ checkValueLength() [3/3]

void casacore::PlainColumn::checkValueLength ( const void * ) const

inlineprotected

Check the length of a value.

This a meant for String values for which a maximum length is defined. The void* version is a no-op for other values.

Definition at line 190 of file PlainColumn.h.

virtual

Get a pointer to the underlying column cache.

Implements casacore::BaseColumn.

◆ createDataManagerColumn()

virtual void casacore::PlainColumn::createDataManagerColumn ( )

pure virtual

Create a data manager column for a filled column.

Implemented in casacore::ScalarRecordColumnData, casacore::ScalarColumnData< T >, and casacore::ArrayColumnData.

◆ dataManager()

DataManager * casacore::PlainColumn::dataManager ( ) const

Read the column.

◆ getFileDerived()

virtual void casacore::PlainColumn::getFileDerived	(	AipsIO &	,

Read the column back.

The control information is read from the given AipsIO object. This is used to bind the column to the appropriate data manager.

Implemented in casacore::ScalarRecordColumnData, casacore::ScalarColumnData< T >, and casacore::ArrayColumnData.

◆ isBound()

virtual Bool casacore::PlainColumn::isBound ( ) const

virtual

Test if the column is bound to a storage manager or virtual column engine.

virtual

Test if the column is stored (otherwise it is virtual).

Implements casacore::BaseColumn.

◆ isWritable()

virtual Bool casacore::PlainColumn::isWritable ( ) const

virtual

Test if the column is in principle writable.

This does not test if the table itself is writable. That has to be done by the caller.

Implements casacore::BaseColumn.

TableRecord& casacore::PlainColumn::keywordSet ( )

virtual

Implements casacore::BaseColumn.

◆ nrow()

rownr_t casacore::PlainColumn::nrow ( ) const

		const TableAttr &
	)

Write the column.

virtual void casacore::PlainColumn::putFileDerived ( AipsIO & )

protectedpure virtual

Write the column.

The control information is written into the given AipsIO object, while the data is written by the storage manager.

Implemented in casacore::ScalarRecordColumnData, casacore::ScalarColumnData< T >, and casacore::ArrayColumnData.

◆ rwKeywordSet()

TableRecord& casacore::PlainColumn::rwKeywordSet ( )

virtual

Get access to the column keyword set.

◆ setMaximumCacheSize()

virtual void casacore::PlainColumn::setMaximumCacheSize ( uInt nbytes )

virtual

Set the maximum cache size (in bytes) to be used by a storage manager.

◆ setShapeColumn()

virtual void casacore::PlainColumn::setShapeColumn ( const IPosition & shape )
