Etymology

ColumnDescSet is the set of column descriptions in a table description.

Synopsis

ColumnDescSet is used by TableDesc to store all column descriptions.

In principle this class is only used internally by the table system. However, there is a function in TableDesc which gives const access to this class. This can be used by the user to call functions like isDisjoint.

◆ ColumnDescSet() [1/2]

casacore::ColumnDescSet::ColumnDescSet ( )

◆ ColumnDescSet() [2/2]

casacore::ColumnDescSet::ColumnDescSet ( const ColumnDescSet & )

Member Function Documentation

◆ add()

void casacore::ColumnDescSet::add ( const ColumnDescSet & set )

private

Add another (disjoint) column set.

If the sets are not disjoint (i.e. the other set contains a column with an already existing name, an exception is thrown and nothing of the other set is added.

References ColumnDescSet().

◆ addColumn() [1/2]

ColumnDesc & casacore::ColumnDescSet::addColumn ( const ColumnDesc & )

private

Add a column.

An exception is thrown if a column with this name already exists.

◆ addColumn() [2/2]

ColumnDesc & casacore::ColumnDescSet::addColumn	(	const ColumnDesc &	,
		const String &	newname )

private

Add a column with another name.

An exception is thrown if a column with this name already exists.

◆ allExist()

Bool casacore::ColumnDescSet::allExist	(	const ColumnDescSet &	,
		Bool &	equalDataTypes ) const

private

Test if all columns are part of the other set.

The flag equalDataTypes is set to True if the data types of the columns in both sets are the same.

References ColumnDescSet().

◆ checkSubTableDesc()

void casacore::ColumnDescSet::checkSubTableDesc ( ) const

Check recursevily if the descriptions of all subtables are known.

◆ getFile()

void casacore::ColumnDescSet::getFile	(	AipsIO &	,
		const TableAttr &	)

private

Get the object.

◆ isDefined()

Bool casacore::ColumnDescSet::isDefined ( const String & name ) const

inline

Test if a column is defined in this set.

Definition at line 112 of file ColDescSet.h.

References cols_p, and casacore::name().

◆ isDisjoint()

Bool casacore::ColumnDescSet::isDisjoint ( const ColumnDescSet & other ) const

Test if this and the other column set are disjoint.

References ColumnDescSet().

◆ isEqual()

Bool casacore::ColumnDescSet::isEqual	(	const ColumnDescSet &	other,
		Bool &	equalDataTypes ) const

Test if this set equals another one.

It is equal if the number of columns is equal and all field names in this set occur in the other too. The order of the columns is not important.
The flag equalDataTypes is set to True if the data types of all columns match.

References ColumnDescSet().

◆ isStrictSubset()

Bool casacore::ColumnDescSet::isStrictSubset	(	const ColumnDescSet &	other,
		Bool &	equalDataTypes ) const

Test if this set is a strict subset of another one, thus if it is a subset and not equal.

References ColumnDescSet().

Referenced by isStrictSuperset().

◆ isStrictSuperset()

Bool casacore::ColumnDescSet::isStrictSuperset	(	const ColumnDescSet &	other,
		Bool &	equalDataTypes ) const

inline

Test if this set is a strict superset of another one, thus if it is a superset and not equal.

Definition at line 138 of file ColDescSet.h.

References ColumnDescSet(), and isStrictSubset().

◆ isSubset()

Bool casacore::ColumnDescSet::isSubset	(	const ColumnDescSet &	other,
		Bool &	equalDataTypes ) const

Test if this set is a subset of another one.

It is similar to isEqual above.

References ColumnDescSet().

Referenced by isSuperset().

◆ isSuperset()

Bool casacore::ColumnDescSet::isSuperset	(	const ColumnDescSet &	other,
		Bool &	equalDataTypes ) const

inline

Test if this set is a superset of another one.

uInt casacore::ColumnDescSet::ncolumn ( ) const

inline

Get nr of columns in this set.

ColumnDescSet & casacore::ColumnDescSet::operator= ( const ColumnDescSet & )

Assignment (copy semantics).

References ColumnDescSet().

◆ operator[]() [1/4]

ColumnDesc & casacore::ColumnDescSet::operator[] ( const String & name )

Get a column by its name.

◆ operator[]() [3/4]

ColumnDesc & casacore::ColumnDescSet::operator[] ( uInt index )

inline

Get a column by its index.

		const TableAttr &	) const

private

Put the object.

◆ remove()

void casacore::ColumnDescSet::remove ( const String & name )

private

Remove a column.

An exception is thrown if the column with this name does not exist.
