java.lang.Object
  org.apache.tuscany.sca.node.SCANodeFactory

Direct Known Subclasses:

NodeFactoryImpl

public abstract class SCANodeFactory
extends java.lang.Object

A factory for SCA processing nodes. An SCA processing node can be loaded with an SCA composite and the SCA contributions required by the composite.

Method Detail

newInstance

public static SCANodeFactory newInstance()

Returns a new SCA node factory instance.

Returns:

a new SCA node factory

createSCANodeFromClassLoader

public abstract SCANode createSCANodeFromClassLoader(java.lang.String compositeURI,
                                                     java.lang.ClassLoader classLoader)

Create a SCA node based on the discovery of the contribution on the classpath for the given classloader. This method should be treated a convinient shortcut with the following assumptions:

• This is a standalone application and there is a deployable composite file on the classpath.
• There is only one contribution which contains the deployable composite file physically in its packaging hierarchy.

Parameters:

compositeURI - The URI of the composite file relative to the root of the enclosing contribution

classLoader - The ClassLoader used to load the composite file as a resource. If the value is null, then thread context classloader will be used

Returns:

A newly created SCA node

createSCANodeFromURL

public abstract SCANode createSCANodeFromURL(java.lang.String configurationURL)

Creates a new SCA node from the configuration URL

Parameters:

configurationURL - the URL of the node configuration which is the ATOM feed that contains the URI of the composite and a collection of URLs for the contributions

Returns:

a new SCA node.

createSCANode

public abstract SCANode createSCANode(java.lang.String compositeURI,
                                      SCAContribution... contributions)

Creates a new SCA node.

Parameters:

compositeURI - the URI of the composite to use

contributions - the URI of the contributions that provides the composites and related artifacts. If the list is empty, then we will use the thread context classloader to discover the contribution on the classpath

Returns:

a new SCA node.

createSCANode

public abstract SCANode createSCANode(java.lang.String compositeURI,
                                      java.lang.String compositeContent,
                                      SCAContribution... contributions)

Creates a new SCA node.

Parameters:

compositeURI - the URI of the composite to use

compositeContent - the XML content of the composite to use

contributions - the URI of the contributions that provides the composites and related artifacts

Returns:

a new SCA node.
