org.apache.beehive.controls.api.assembly.ControlAssemblyContext
Control assemblers are passed a ControlAssemblyContext at the time they are invoked; the context allows the assemblers to interact with their external environment (checking files, side-effecting deployment descriptors, emitting code parameterized by the specifics of the control extension, etc). Beehive provides ControlAssemblyContext implementations that expose the standard environments of J2EE applications and modules. Vendor-specific implementations may provide access to their specific environment information, such as vendor-specific descriptors, via definition and implementation of additional interfaces. ControlAssemblers should use reflection to determine if the ControlAssemblyContext implementation they are passed supports a particular set of environment features.

                Class<? extends ControlAssembler> assemblerClass = a.assembler();
                if ( !assemblerClass.equals(DefaultControlAssembler.class) )
                {
                    ControlAssembler assembler = assemblerClass.newInstance();
                    Set<String> clients = controlTypeToClients.get( ct );
                    ControlAssemblyContext cac = factory.newInstance(
                        cl.loadClass(ct), null, clients, moduleRoot, moduleName, srcOutputRoot );
                    assembler.assemble( cac );
                }
            }
