Synopsis

This class is derived from TableExprGroupFuncBase and act as the abstract base class for aggregate functions resulting in a double array.
Derived classes can use itsValue to contain the aggregated value. It that case they do not need to implement the get function.

Member Function Documentation

Bool casacore::TableExprGroupFuncArrayDouble::checkShape	(	const MArrayBase &	arr,
		const String &	func
	)			`[protected]`

If not empty, check if the shape matches that of itsValue.

If itsValue is still empty, it is sized.
