Method Detail

addDescription

SharedObjectTypeDescription addDescription(SharedObjectTypeDescription description)

getDescriptions

java.util.List getDescriptions()

Get a collection of the SharedObjectTypeDescriptions currently known to this factory. This allows clients to query the factory to determine what if any other SharedObjectTypeDescriptions are currently registered with the factory, and if so, what they are.

Returns:

List of SharedObjectTypeDescription instances

containsDescription

boolean containsDescription(SharedObjectTypeDescription description)

Check to see if a given named description is already contained by this factory

Parameters:

description - the SharedObjectTypeDescription to look for

Returns:

true if description is already known to factory, false otherwise

getDescriptionByName

SharedObjectTypeDescription getDescriptionByName(java.lang.String name)
                                                 throws SharedObjectCreateException

Get the known SharedObjectTypeDescription given it's name.

Parameters:

name -

Returns:

SharedObjectTypeDescription found

Throws:

SharedObjectCreateException

createSharedObject

ISharedObject createSharedObject(SharedObjectTypeDescription typeDescription,
                                 java.lang.String[] argTypes,
                                 java.lang.Object[] args)
                                 throws SharedObjectCreateException

Create ISharedObject instance. Given a SharedObjectTypeDescription object, a String [] of argument types, and an Object [] of parameters, this method will

• lookup the known SharedObjectTypeDescriptions to find one of matching name
• if found, will retrieve or create an ISharedObjectInstantiator for that description
• Call the ISharedObjectInstantiator.createInstance method to return an instance of ISharedObject

Parameters:

typeDescription - the SharedObjectTypeDescription to use to create the instance

argTypes - a String [] defining the types of the args parameter

args - an Object [] of arguments passed to the createInstance method of the ISharedObjectInstantiator

Returns:

a valid instance of ISharedObject

Throws:

SharedObjectCreateException

createSharedObject

ISharedObject createSharedObject(java.lang.String descriptionName)
                                 throws SharedObjectCreateException

• lookup the known SharedObjectTypeDescriptions to find one of matching name
• if found, will retrieve or create an ISharedObjectInstantiator for that description
• Call the ISharedObjectInstantiator.createInstance method to return an instance of ISharedObject

Parameters:

descriptionName - the SharedObjectTypeDescription name to lookup

Returns:

a valid instance of ISharedObject

Throws:

SharedObjectCreateException
