Package com.orchestranetworks.addon.dint.transformation Description

Provides classes and interfaces to define and register transformations.

A transformation can be add to SourceFieldMappingStep or the other TransformationMappingStep. The Java API allows to execute many transformations as a chain.

For example:

1. User wants to upper case the string data before insert to the target table:

   - First, get SourceFieldMappingStep from TableMapping.
   - Use StringUpperCase transformation to upper this source field.
   - Finally, map with the target field.

2. User wants to add more prefix 'Mr/Ms' to name field and insert to the target table:

   - First get ConstantTransformationMappingStep from TableMapping.
   - Use StringConcat transformation to concatenate with the name field from the source table.
   - Finally, map with the target field.

3. User wants to upper case only the first name of the full name string and insert to the target table:

   - First, get SourceFieldMappingStep from TableMapping.
   - Use StringSplit transformation to split full name string into two variable 'firstName' and 'lastName'.
   - Use StringUpperCase transformation to upper case the variable 'firstName'.
   - Use StringConcat transformation to concatenate with the variable 'lastName', the output of the previous split step.
   - Finally, map with the target field.

A custom transformation needs to be registered to be displayed in the mapping screen:

        TransformationRegistry.getInstance().add(new ACustomTransformationDefinition());
