Constructor & Destructor Documentation

casa::PassiveTableDD::PassiveTableDD ( Table * table )

Constructor taking a pointer to an already constructed Table.

The Table will be deleted by this class.

casa::PassiveTableDD::PassiveTableDD ( const String tablename )

Constructor taking a String which describes the full pathname of a Table on disk.

virtual casa::PassiveTableDD::~PassiveTableDD ( ) [virtual]

Destructor.

casa::PassiveTableDD::PassiveTableDD ( ) [protected]

(Required) default constructor.

casa::PassiveTableDD::PassiveTableDD ( const PassiveTableDD & other ) [protected]

(Required) copy constructor.

Member Function Documentation

Bool casa::PassiveTableDD::arrangeQueryTable ( ) [private]

Arrange the query table (generally called after installing new options).

template<class T >

Bool casa::PassiveTableDD::getColumnKeyword	(	T &	value,
		const String	column,
		const String	keyword
	)		const `[protected]`

Get the value of the named keyword, or the first keyword matching regex for the named column, and return it in value.

The return value is True for success, and False for failure, which is the result if the wrong type T is requested, or if the keyword doesn't exist.

template<class T >

Bool casa::PassiveTableDD::getColumnKeyword	(	T &	value,
		const String	column,
		const Regex &	regex
	)		const `[protected]`

Vector<String> casa::PassiveTableDD::getColumnNamesOfType ( const DataType type ) [protected]

Get the names of the columns of the table having the given type.

virtual Record casa::PassiveTableDD::getOptions ( ) [virtual]

Retrieve the current and default options and parameter types.

Reimplemented from casa::PassiveCachingDD.

Reimplemented in casa::SkyCatOverlayDD.

template<class T >

Bool casa::PassiveTableDD::getTableKeyword	(	T &	value,
		const String	keyword
	)		const `[protected]`

Get the value of the named keyword, or the first keyword matching regex, and return it in value.

The return value is True for success, and False for failure, which is the result if the wrong type T is requested.

template<class T >

Bool casa::PassiveTableDD::getTableKeyword	(	T &	value,
		const Regex &	regex
	)		const `[protected]`

void casa::PassiveTableDD::installDefaultOptions ( ) [private]

Install the default options for this DisplayData.

Reimplemented from casa::CachingDisplayData.

void casa::PassiveTableDD::operator= ( const PassiveTableDD & other ) [protected]

(Required) copy assignment.

virtual AttributeBuffer casa::PassiveTableDD::optionsAsAttributes ( ) [virtual]

Return the current options of this DisplayData as an AttributeBuffer.

Reimplemented from casa::PassiveCachingDD.

Reimplemented in casa::SkyCatOverlayDD.

virtual void casa::PassiveTableDD::setDefaultOptions ( ) [virtual]

Install the default options for this DisplayData.

Reimplemented from casa::PassiveCachingDD.

Reimplemented in casa::SkyCatOverlayDD.

virtual Bool casa::PassiveTableDD::setOptions	(	Record &	rec,
		Record &	recOut
	)		`[virtual]`

Apply options stored in rec to the DisplayData.

A return value of True means a refresh is needed. recOut contains any fields which were implicitly changed as a result of the call to this function.

Reimplemented from casa::PassiveCachingDD.

Reimplemented in casa::SkyCatOverlayDD.

Table* casa::PassiveTableDD::table ( ) [protected]

Return the Table pointer for use by derived classes.

If a query is active (via setOptions), then the result of the query is returned, otherwise the construction Table is returned.
