Abstract base class for a node having 0, 1, or 2 child nodes.
Internal
TableExprNodeBinary is a node in the table expression tree representing a binary node (i.e. having 2 operands).
TableExprNodeBinary is the abstract base class for all nodes in a table expression tree using up to 2 operands. It is used as the base class for the node classes representing operator +, -, etc..
This class contains the common functionality for the classes representing a binary (or unary) operator.

When one of the children is a constant, convert its data type to that of the other operand.
This avoids that conversions are done for each get.
Reimplemented from casacore::TableExprNodeRep.
|
static |
Link the children to the node and convert the children to constants if needed and possible.
Also convert the node to constant if possible. The operand data types can be adapted as needed.
|
virtual |
Get the nodes representing an aggregate function.
Reimplemented from casacore::TableExprNodeRep.
Reimplemented in casacore::TableExprUDFNodeArray, casacore::TableExprFuncNodeArray, and casacore::TableExprAggrNodeArray.
|
virtual |
Get the nodes representing a table column.
Reimplemented from casacore::TableExprNodeRep.
Reimplemented in casacore::TableExprNodeColumn, casacore::TableExprNodeArrayColumn, casacore::TableExprUDFNodeArray, and casacore::TableExprFuncNodeArray.

virtual |
Handle the units of the children and possibly set the parent's unit.
The default implementation make the units of the children equal and set the parent unit to that unit if the parent is not a Bool value.
