Packages that use ProcessingComponent

org.jboss.dna.graph.query.process

This package defines the QueryProcessor interface, which is responsible for constructing for each query a tree of ProcessingComponent objects that each are responsible for processing a specific aspect of the query and returning the tuples to the parent component.
