static TableExprNodeRep* casacore::TableExprConeNode::fillNode ( TableExprConeNode *  thisNode,
PtrBlock< TableExprNodeRep *> &  nodes,
const Block< Int > &  dtypeOper 
)
static

Link the children to the node and convert the children to constants if possible.

Also convert the node to constant if possible.

§ findNelem()

static Int casacore::TableExprConeNode::findNelem ( const TableExprNodeRep *  node)
staticprivate

Find the number of elements in an argument.

It returns -1 if unknown.

§ getBool()

Bool casacore::TableExprConeNode::getBool ( const TableExprId &  id)
virtual

'get' Functions to get the desired result of a function.

Reimplemented from casacore::TableExprNodeRep.

§ getInt()

Int64 casacore::TableExprConeNode::getInt ( const TableExprId &  id)
virtual

Reimplemented from casacore::TableExprNodeRep.

§ tryToConst()

void casacore::TableExprConeNode::tryToConst ( )
private

Try if the function gives a constant result.

If so, set the expression type to Constant.
