Method Detail- 
createInstancepublic IContainer createInstance(ContainerTypeDescription description, Object[] parameters) Description copied from interface:IContainerInstantiatorCreate instance of IContainer. This is the interface that container provider implementations must implement for the containerFactory extension point. The caller may optionally specify both argument types and arguments that will be passed into this method (and therefore to the provider implementation implementing this method). For example:ContainerFactory.getDefault().createContainer("foocontainer",new Object { "hello" }); - Specified by:
- createInstancein interface- IContainerInstantiator
- Parameters:
- description- the ContainerTypeDescription associated with the registered container provider implementation
- parameters- parameters specified by the caller. May be null if no parameters are passed in by caller to ContainerFactory.getDefault().createContainer(...)
- Returns:
- IContainer instance. The provider implementation must return a valid object implementing IContainer OR throw a ContainerCreateException. Null will not be returned.
 
 - 
getSupportedAdapterTypespublic String[] getSupportedAdapterTypes(ContainerTypeDescription description) Description copied from interface:IContainerInstantiatorGet array of supported adapters for the given container type description. Providers implement this method to allow clients to inspect the adapter types exposed by the container described by the given description. The returned array entries will be the fully qualified names of the adapter classes. Note that the returned types do not guarantee that a subsequent call toIContainer.getAdapter(Class)with the same type name as a returned value will return a non-nullresult. In other words, even if the class name is in the returned array, subsequent calls toIContainer.getAdapter(Class)may still returnnull.- Specified by:
- getSupportedAdapterTypesin interface- IContainerInstantiator
- Parameters:
- description- the ContainerTypeDescription to report adapters for. Must not be- null.
- Returns:
- String[] of supported adapters. The entries in the returned array
         will be the fully qualified class names of adapters supported by
         the given description. nullmay be returned by the provider if no adapters are supported for this description.

- getSupportedIntentsin interface- IContainerInstantiator

getSupportedParameterTypespublic Class[][] getSupportedParameterTypes(ContainerTypeDescription description) Description copied from interface:IContainerInstantiatorGet array of parameter types for given container type description. Providers implement this method to allow clients to inspect the available set of parameter types understood for calls toIContainerInstantiator.createInstance(ContainerTypeDescription, Object[]).Each of the rows of the returned array specifies a Class[] of parameter types. These parameter types correspond to the types of Object[] that can be passed into the second parameter of IContainerInstantiator.createInstance(ContainerTypeDescription, Object[]).Consider the following example: public Class[][] getSupportedParameterTypes() { return new Class[][] { { String.class }, { String.class, String.class } }; }The above means that there are two acceptable values for the Object [] passed intoIContainerInstantiator.createInstance(ContainerTypeDescription, Object[]): 1) a single String, and 2) two Strings. These would therefore be acceptable as input to createInstance:IContainer container = ContainerFactory.getDefault().createContainer( description, new Object[] { "Hello" }); IContainer container2 = ContainerFactory.getDefault().createContainer( description, new Object[] { "Hello" });- Specified by:
- getSupportedParameterTypesin interface- IContainerInstantiator
- Parameters:
- description- the ContainerTypeDescription to return parameter types for
- Returns:
- Class[][] array of Class[]s. Each row in the table corresponds to
         a Class[] that describes the types of Objects in Object[] for
         second parameter to
         IContainerInstantiator.createInstance(ContainerTypeDescription, Object[]).nullreturned if no parameter types supported for given description.
