/**
 * Classes that implement this interface indicate that they take responsibility for generating their dependencies as the dependency
 * graph is being created.
 * 
 * Some of their dependencies depend on which nodes are in the current template and therefore can't be declared in the spring
 * configuration file in a static way.  For example the MergeDataSourceProcessor must run after all of its source, since its sources
 * differ from one configuration to another they must be determined at runtime.
 *
 * The test for this class will be part of {@link org.mapfish.print.processor.jasper.MergeDataSourceProcessor} tests.
