Interface EngineConfiguration

All Known Subinterfaces:

WSDDEngineConfiguration

public interface EngineConfiguration

EngineConfiguration is an interface that the Message Flow subsystem provides so that engine configuration can be provided in a pluggable way. An instance of EngineConfiguration provides configuration for a particular engine instance.

Concrete implementations of this interface will obtain configuration information from some source (examples might be files, Strings, or databases) and are responsible for writing it into an AxisEngine, and writing an AxisEngine's state back out to whatever storage medium is in use.

Field Summary

static java.lang.String

PROPERTY_NAME Property name used for setting an EngineConfiguration to be used in creating engines.

Method Summary

void	configureEngine(AxisEngine engine) Configure this AxisEngine using whatever data source we have.
java.util.Iterator	getDeployedServices() Get an enumeration of the services deployed to this engine.
java.util.Hashtable	getGlobalOptions() Returns the global configuration options.
Handler	getGlobalRequest() Returns a global request handler.
Handler	getGlobalResponse() Returns a global response handler.
Handler	getHandler(QName qname) Retrieve an instance of the named handler.
java.util.List	getRoles() Get a list of roles that this engine plays globally.
org.apache.axis.handlers.soap.SOAPService	getService(QName qname) Retrieve an instance of the named service.
org.apache.axis.handlers.soap.SOAPService	getServiceByNamespaceURI(java.lang.String namespace) Get a service which has been mapped to a particular namespace.
Handler	getTransport(QName qname) Retrieve an instance of the named transport.
org.apache.axis.encoding.TypeMappingRegistry	getTypeMappingRegistry() Retrieve the TypeMappingRegistry for this engine.
void	writeEngineConfig(AxisEngine engine) Read the configuration from an engine, and store it somehow.
