Method Detail

setup

default void setup(TransformationConfigurationContext context)
            throws DataIntegrationException

Allows retrieving parameters from TransformationConfigurationContext to set up for the transform(TransformationExecutionContext) method.

For each instance of this function, the method is invoked only once. It does nothing by default.

If an exception happens when setting up any transformation function, the whole data integration task will not be performed.

All transformation errors of a table mapping can be retrieved from TableMappingResult.getErrorMessages().

Throws:

DataIntegrationException - A transformation error with user-friendly content.

transform

O transform(TransformationExecutionContext<I> context)
     throws DataIntegrationException

Performs the transformation.

Iterated invocation based on the source data.

If an exception happens, any other transformation functions configured after the current one will be skipped. The data integration task will not be interrupted and the next source data will be processed.

All transformation errors of a table mapping can be retrieved from TableMappingResult.getErrorMessages().

Throws:

DataIntegrationException - A transformation error with user-friendly content.
