Interface PartFillComponent

All Known Implementing Classes:
BasePartFillComponent, SubreportFillPart

A component handler used while filling the report.

The fill component implementation is responsible for managing a component at fill time. A typical implementation would evaluate a set of expressions and create a print element to be included in the generated report.
