Class EndpointFactory

java.lang.Object

org.apache.synapse.config.xml.endpoints.EndpointFactory

All Implemented Interfaces:

XMLToObjectMapper

Direct Known Subclasses:

ClassEndpointFactory, DefaultEndpointFactory, DynamicLoadbalanceEndpointFactory, FailoverEndpointFactory, IndirectEndpointFactory, LoadbalanceEndpointFactory, RecipientListEndpointFactory, ResolvingEndpointFactory, SALoadbalanceEndpointFactory, ServiceDynamicLoadbalanceEndpointFactory, TemplateEndpointFactory

public abstract class EndpointFactory
extends Object
implements XMLToObjectMapper

All endpoint factories should extend from this abstract class. Use EndpointFactory to obtain the correct endpoint for particular endpoint configuration. As endpoints can be nested inside each other, EndpointFactory implementations may call other EndpointFactory implementations recursively to obtain the required endpoint hierarchy.

This also serves as the XMLToObjectMapper implementation for specific endpoint implementations. If the endpoint type is not known use XMLToEndpointMapper as the generic XMLToObjectMapper for all endpoints.

getEndpointFromElement

public static Endpoint getEndpointFromElement(org.apache.axiom.om.OMElement elem,
                                              boolean isAnonymous,
                                              Properties properties)

Core method which is exposed for the external use, and this will find the proper EndpointFactory and create the endpoint which is of the format Endpoint.

Parameters:

elem - XML from which the endpoint will be built

isAnonymous - whether this is an anonymous endpoint or not

properties - bag of properties to pass in any information to the factory

Returns:

created endpoint

getEndpointFromElement

public static Endpoint getEndpointFromElement(org.apache.axiom.om.OMElement elem,
                                              DefinitionFactory factory,
                                              boolean isAnonymous,
                                              Properties properties)

Core method which is exposed for the external use, and this will find the proper EndpointFactory and create the endpoint which is of the format Endpoint.However definition for this endpoint will be built using a custom Endpoint Defn factory.

Parameters:

elem - XML from which the endpoint will be built

factory - custom definition factory which this endpoint will be used to build

isAnonymous - whether this is an anonymous endpoint or not

properties - bag of properties to pass in any information to the factory

Returns:

created endpoint

getObjectFromOMNode

public Object getObjectFromOMNode(org.apache.axiom.om.OMNode om,
                                  Properties properties)

Creates the Endpoint object from the provided OMNode

Specified by:

getObjectFromOMNode in interface XMLToObjectMapper

Parameters:

om - XML node from which the endpoint will be built

properties - bag of properties to pass in any information to the factory

Returns:

created endpoint as an Object

createEndpoint

protected abstract Endpoint createEndpoint(org.apache.axiom.om.OMElement epConfig,
                                           boolean anonymousEndpoint,
                                           Properties properties)

Creates the Endpoint implementation for the given XML endpoint configuration. If the endpoint configuration is an inline one, it should be an anonymous endpoint. If it is defined as an immediate child element of the definitions tag it should have a name, which is used as the key in local registry.

Parameters:

epConfig - OMElement containing the endpoint configuration.

anonymousEndpoint - false if the endpoint has a name. true otherwise.

properties - bag of properties to pass in any information to the factory

Returns:

Endpoint implementation for the given configuration.

extractSpecificEndpointProperties

protected void extractSpecificEndpointProperties(EndpointDefinition definition,
                                                 org.apache.axiom.om.OMElement elem)

getEndpoints

protected ArrayList<Endpoint> getEndpoints(org.apache.axiom.om.OMElement listEndpointElement,
                                           Endpoint parent,
                                           Properties properties)

Helper method to construct children endpoints

Parameters:

listEndpointElement - OMElement representing the children endpoints

parent - Parent endpoint

properties - bag of properties to pass in any information to the factory

Returns:

List of children endpoints

setEndpointDefinitionFactory

public void setEndpointDefinitionFactory(DefinitionFactory factory)

provide a custom Endpoint definition factory

Parameters:

factory -

getEndpointDefinitionFactory

public DefinitionFactory getEndpointDefinitionFactory()
