Class ProcessorDependencyGraph

java.lang.Object

org.mapfish.print.processor.ProcessorDependencyGraph

public final class ProcessorDependencyGraph
extends Object

Represents a graph of the processors dependencies. The root nodes can execute in parallel but processors with dependencies must wait for their dependencies to complete before execution.
