Constructor Detail

EntryPointContextImpl

public EntryPointContextImpl(java.lang.String name,
                             SourceWireFactory sourceWireFactory,
                             MessageFactory messageFactory)
                      throws ContextInitException

Creates a new entry point

Parameters:

name - the entry point name

sourceWireFactory - the proxy factory containing the invocation chains for the entry point

messageFactory - a factory for generating invocation messages

Throws:

ContextInitException - if an error occurs creating the entry point

Method Detail

getInstance

public java.lang.Object getInstance(QualifiedName qName)
                             throws TargetException

Description copied from interface: Context

Returns the instance associated with the requested name, which may be in a atomic or composite form. Atomic (i.e. leaf) contexts will return an instance associated with the service name part of the compound name, which may be null.

Composite contexts will return an instance (likely a proxy) of a contained entry point context. In this case, the port name on the qualified name will correspond to the composite context name and the part name will be used to retrieve the contained entry point context. The latter may be null. If the contained context is not an entry point context, an exception will be thrown.

Specified by:

getInstance in interface Context

Parameters:

qName - a qualified name of the requested instance

Returns:

the implementation instance or a proxy to it

Throws:

TargetException - if an error occurs retrieving the instance or the requested component is not an entry point.
