DataGenerator requires a transformation which can be written in both CTL and Java.

For more information about the interface, see Java Interface.

Remember that this component allows sending of each record through a connected output port whose number equals the value returned by the transformation (Return Values of Transformations). Mapping must be defined for such a port.

JMSReader allows optionally a transformation which can be written in Java only.

For more information about the interface, see Java Interfaces for JMSReader.

Remember that this component sends each record through all of the connected output ports. Mapping does not need to be defined.

MultiLevelReader requires a transformation which can only be written in Java.

For more information, see Java Interfaces for MultiLevelReader.
