Interface XMLExecution

All Superinterfaces:

Execution, ResultSetExecution

All Known Implementing Classes:

BaseStreamingExecution, FileExecution, HTTPExecution, SOAPExecution

public interface XMLExecution
extends ResultSetExecution

An XMLExecution is responsible for responding to a Query. Depending upon the query and the source of the XML, this can sometimes require multiple trips to the source system. For example, as SOAP service that converts temperature: int convertToFahrenheit(int degreesCelsius) might be modeled as a Table called TempConversion with a column for celsius of type int and a column for fahreneheit also of type int. when queried like this: SELECT fahrenheit FROM TempConversion WHERE celsius IN (40, 20) The XMLExecution has to make two calls to the service to create the correct result set. The multiple calls are abstracted within the ResultProducer.
