org.pentaho.reporting.engine.classic.core.function.OutputFunction
A simple tagging interface for the transition from function-based layouting back to explicit layouting. Output functions are always considered internal information, so there is no way to write a report-processor that is not aware of the actual implementation of the output-function. @author Thomas Morgner
