All Implemented Interfaces:

Serializable, IPreparedComponent, IAuditable, IComponent, ILogger, IParameterResolver

Direct Known Subclasses:

XQueryLookupRule

public abstract class XQueryBaseComponent
extends ComponentBase
implements IPreparedComponent

XQueryBaseComponent provides a mechanism to run xqueries within the Pentaho BI Platform. TODO: In regards to IPreparedComponent, implement a method for choosing the datasource on the fly
