IBM InfoSphere Federation Server, Version 9.7

RuntimeDataDesc class (Java)

The federated server creates the RuntimeDataDesc class to describe each column value that is transferred between the federated server and a wrapper.

A column value can be either one of the following items:
  • A portion of a result row that is transferred from the wrapper to the federated server.
  • A value to be bound to a runtime parameter in a query that is submitted to the wrapper by the federated server.

The RuntimeDataDesc class is one of the data classes for the Java™ API.

Usage

For both RemoteQuery and RemotePassthru objects, the federated server creates a RuntimeDataDesc instance for each RuntimeData object in the input data list that represents the parameter values. The federated server supplies the column descriptions. For RemoteQuery objects, the federated server also creates a RuntimeDataDesc instance for each RuntimeData object in the output data list that represents values in result rows. The federated server supplies these column descriptions as well. The wrapper writer creates instances of the RuntimeDataDesc class to describe the result set of a pass-through session in the RemotePassthru.describe method.
