Synopsis

This class is used to assemble several table expression nodes. It is used for 3 purposes:

To hold the arguments of a function. All set elements must be single.
To hold the variables of an index for an array slice. All set elements must be of type int scalar and they must represent a discrete interval (which includes single).
To hold the elements of a set used with the IN operator. All set elements must be scalars of any type.

The type of all set elements has to be the same. The set consists of TableExprNodeSetElem elements. The add function has to be used to add an element to the set.

It is possible to construct the object directly from an IPosition object. In that case all elements are single. Furthermore it is possible to construct it directly from a Slicer object. In that case all elements represent a discrete interval.

Member Typedef Documentation

typedef Bool(TableExprNodeSet::* casacore::TableExprNodeSet::FindFuncPtr)(Double value) [private]

Define the functions to find a double, which depend on open/closed-ness.

In this way a test on open/closed is done only once.

Definition at line 459 of file ExprNodeSet.h.

Constructor & Destructor Documentation

casacore::TableExprNodeSet::TableExprNodeSet ( )

Construct an empty set.

casacore::TableExprNodeSet::TableExprNodeSet ( const IPosition & )

Construct from an IPosition.

The number of elements in the set is the number of elements in the IPosition. All set elements are single values.

casacore::TableExprNodeSet::TableExprNodeSet ( const Slicer & )

Construct from a Slicer.

The number of elements in the set is the dimensionality of the Slicer. All set elements are discrete intervals. Their start and/or end is undefined if it is was not defined (i.e. Slicer::MimicSource used) in the Slicer object.

casacore::TableExprNodeSet::TableExprNodeSet	(	const Vector< uInt > &	rownrs,
		const TableExprNodeSet &
	)

Construct a set with n*set.nelements() elements where n is the number of rows.

Element i is constructed by evaluating the input element for row rownr[i].

casacore::TableExprNodeSet::~TableExprNodeSet ( )
