Constructor & Destructor Documentation

◆ ImageAttrGroupCasa() [1/2]

casacore::ImageAttrGroupCasa::ImageAttrGroupCasa ( )

inline

The default constructor creates a null object.

Definition at line 61 of file ImageAttrGroupCasa.h.

◆ ImageAttrGroupCasa() [2/2]

casacore::ImageAttrGroupCasa::ImageAttrGroupCasa	(	const Table &	image,
		const String &	attrGroupName
	)

Construct the object for an attribute group in the image table.

Note that the group name is the name of a subtable containing the info.

◆ ~ImageAttrGroupCasa()

virtual casacore::ImageAttrGroupCasa::~ImageAttrGroupCasa ( )

virtual

Member Function Documentation

◆ addNewColumn()

Bool casacore::ImageAttrGroupCasa::addNewColumn	(	const String &	attrName,
		const ValueHolder &
	)

private

Add a new column for the given attribute for the data type in the value.

◆ attrNames()

virtual Vector<String> casacore::ImageAttrGroupCasa::attrNames ( ) const

virtual

Get all attribute names.

Implements casacore::ImageAttrGroup.

◆ checkRows()

void casacore::ImageAttrGroupCasa::checkRows	(	const String &	attrName,
		uInt	size
	)

private

Check if the size matches the number of rows.

Add rows if the table is still empty.

◆ dataType()

virtual DataType casacore::ImageAttrGroupCasa::dataType ( const String & attrName ) const

virtual

Get the datatype of a attribute.

It returns TpOther if the attribute is not defined.

Implements casacore::ImageAttrGroup.

◆ flush()

void casacore::ImageAttrGroupCasa::flush ( )

Flush the attibrutes if needed.

◆ getData()

virtual ValueHolder casacore::ImageAttrGroupCasa::getData	(	const String &	attrName,
		uInt	rownr
	)

virtual

Get the data of the given attribute.

Implements casacore::ImageAttrGroup.

◆ getDataRow()

virtual Record casacore::ImageAttrGroupCasa::getDataRow ( uInt rownr )

virtual

Get the data of all attributes in a rows.

Implements casacore::ImageAttrGroup.

◆ getMeasInfo()

virtual Vector<String> casacore::ImageAttrGroupCasa::getMeasInfo ( const String & attrName )

virtual

Get the possible measure info as type and Ref.

An empty vector is returned if the attribute has no MEASINFO.

Implements casacore::ImageAttrGroup.

◆ getUnit()

virtual Vector<String> casacore::ImageAttrGroupCasa::getUnit ( const String & attrName )

virtual

Get the possible units of the values.

An empty vector is returned if the attribute has no units.

Implements casacore::ImageAttrGroup.

◆ hasAttr()

virtual Bool casacore::ImageAttrGroupCasa::hasAttr ( const String & attrName ) const

virtual

Test if an attribute exists.

Implements casacore::ImageAttrGroup.

◆ isNull()

Bool casacore::ImageAttrGroupCasa::isNull ( ) const

inline

Test if it is a null object.

Definition at line 71 of file ImageAttrGroupCasa.h.

References casacore::Table::isNull(), itsTable, and casacore::TableProxy::table().

◆ nrows()

virtual uInt casacore::ImageAttrGroupCasa::nrows ( ) const

virtual

Get the number of rows in the group.

Implements casacore::ImageAttrGroup.

◆ putData()

virtual void casacore::ImageAttrGroupCasa::putData	(	const String &	attrName,
		uInt	rownr,
		const ValueHolder &	data,
		const Vector< String > &	units = `Vector< String >()`,
		const Vector< String > &	measInfo = `Vector< String >()`
	)

virtual

Put the data of the given attribute.

If the table does not contain data yet, it will be sized to the size of the vector. Otherwise the vector size has to match the table size.
If not empty, the units and MEASINFO will be put as column keywords. The MEASINFO vector must be given as type,Ref.

Implements casacore::ImageAttrGroup.
