process

public WorkProcessor.TransformationState<Page> process(@Nullable
                                                       Page probePage)

Description copied from interface: WorkProcessor.Transformation

Processes input elements and returns current transformation state.

Specified by:

process in interface WorkProcessor.Transformation<Page,Page>

Parameters:

probePage - an element to be transformed. Will be null when there are no more elements. In such case transformation should finish processing and flush any remaining data.

Returns:

the current transformation state, optionally bearing a result
