Class to hold multiple table expression nodes.
Public interface
This class is used to assemble several table expression nodes. It is used for 3 purposes:
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.
Definition at line 305 of file ExprNodeSet.h.
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 441 of file ExprNodeSet.h.
casacore::TableExprNodeSet::TableExprNodeSet | ( | ) |
Construct an empty set.
casacore::TableExprNodeSet::TableExprNodeSet | ( | const IPosition & | ) |
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].
