Double comparison >= in table select expression tree.
Internal
This class represents an >= comparison in a table select expression tree. This is defined for all data types. Only the Bool get function is defined, because the result of a compare is always a Bool.

Get a scalar value for this node in the given row.
The appropriate functions are implemented in the derived classes and will usually invoke the get in their children and apply the operator on the resulting values.
Reimplemented from casacore::TableExprNodeRep.

Convert the tree to a number of range vectors which at least select the same things.
This function is very useful to convert the expression to some intervals covering the select expression. This can be used to do a rough fast selection via an index and do the the slower final selection on that much smaller subset. The function can only convert direct comparisons of columns with constants (via ==, !=, >, >=, < or <=) and their combinations using && or ||.
