Synopsis

This class can be seen as a specialization of TableExprFuncNode for functions returning arrays. However, it is derived from TableExprNodeArray to make it possible that the ExprNode classes use all array functionality offered by that base class.
Internally an TableExprFuncNode object is used.

When a TaQL function is used, TableExprFuncNode::checkOperands determines whether the result is a scalar or an array. Thereafter TableExprNode::newFunctionNode creates a TableExprFuncNode for scalars or a TableExprFuncNodeArray for arrays.
