org.pentaho.reporting.engine.classic.core.Band
A report band is a collection of other elements and bands, similiar to an AWT-Container.
This implementation is not synchronized, to take care that you externally synchronize it when using multiple threads to modify instances of this class.
Trying to add a parent of an band as child to the band, will result in an exception. @author David Gilbert @author Thomas Morgner
