java.lang.Objectcom.ibm.db2.wrapper.RequestExpType
The RequestExpType class describes the type of node in an expression tree.
This node can be a column reference, a constant value,
an unbound parameter or an operator.
Usage:
The wrapper never instantiates a RequestExpType object.
The federated server creates these objects and passes them
to the wrapper during query planning.
