Set of table column descriptions

Prerequisite

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.

Constructor & Destructor Documentation

◆ ColumnDescSet() [1/2]

casacore::ColumnDescSet::ColumnDescSet ( )

Construct an empty column set.

◆ ColumnDescSet() [2/2]

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

Copy constructor (copy semantics).

◆ ~ColumnDescSet()

casacore::ColumnDescSet::~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.

◆ 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.

Referenced by casacore::TableDesc::addColumn().

◆ 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.

◆ checkSubTableDesc()

void casacore::ColumnDescSet::checkSubTableDesc ( ) const

Check recursevily if the descriptions of all subtables are known.

Referenced by casacore::TableDesc::checkSubTableDesc().

◆ 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 114 of file ColDescSet.h.

References cols_p.

Referenced by casacore::TableDesc::isColumn().

◆ isDisjoint()

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

Test if this and the other column set are disjoint.

◆ 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.

◆ 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.

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 140 of file ColDescSet.h.

References 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.

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.

Definition at line 135 of file ColDescSet.h.

References isSubset().

◆ ncolumn()

uInt casacore::ColumnDescSet::ncolumn ( ) const
inline

Get nr of columns in this set.

Definition at line 110 of file ColDescSet.h.

References cols_p.

Referenced by casacore::TableDesc::ncolumn().

◆ operator=()

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

Assignment (copy semantics).

◆ operator[]() [1/4]

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

Get a column by its name.

◆ operator[]() [2/4]

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

Definition at line 97 of file ColDescSet.h.

◆ operator[]() [3/4]

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

Get a column by its index.

Definition at line 103 of file ColDescSet.h.

References colSeq_p.

◆ operator[]() [4/4]

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

Definition at line 105 of file ColDescSet.h.

References colSeq_p.

◆ putFile()

void casacore::ColumnDescSet::putFile ( AipsIO &  ios,
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.

Referenced by casacore::TableDesc::removeColumn().

◆ rename()

void casacore::ColumnDescSet::rename ( const String &  newname,
const String &  oldname 
)
private

Rename a column in the set.

An exception is thrown if the new name already exists or if the old name does not exist.

◆ show()

void casacore::ColumnDescSet::show ( ostream &  os) const

Get const access to the column descriptions.

Show the columns in the set.
