Method Details

getSupportedAdapterTypes

public String[] getSupportedAdapterTypes(ContainerTypeDescription description)

Description copied from interface: IContainerInstantiator

Get 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 to IContainer.getAdapter(Class) with the same type name as a returned value will return a non-null result. In other words, even if the class name is in the returned array, subsequent calls to IContainer.getAdapter(Class) may still return null.

Specified by:

getSupportedAdapterTypes in interface IContainerInstantiator

Overrides:

getSupportedAdapterTypes in class BaseContainerInstantiator

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. null may be returned by the provider if no adapters are supported for this description.

getSupportedParameterTypes

public Class[][] getSupportedParameterTypes(ContainerTypeDescription description)

Description copied from interface: IContainerInstantiator

Get 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 to IContainerInstantiator.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 into IContainerInstantiator.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:

getSupportedParameterTypes in interface IContainerInstantiator

Overrides:

getSupportedParameterTypes in class BaseContainerInstantiator

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[]). null returned if no parameter types supported for given description.

getSupportedConfigs

public String[] getSupportedConfigs(ContainerTypeDescription description)

Description copied from interface: IRemoteServiceContainerInstantiator

Get supported configs for the given ContainerTypeDescription. This method will be called to determine what the OSGi remote service supported config types are for the given description during the search for the service exporter provider/containers upon remote service registration.

Specified by:

getSupportedConfigs in interface IRemoteServiceContainerInstantiator

Parameters:

description - the ContainerTypeDescription to return the supported configs for. Will not be null.

Returns:

String[] the supported config types. null may be returned if the given description does not support any config types.

getImportedConfigs

public String[] getImportedConfigs(ContainerTypeDescription description,
 String[] exporterSupportedConfigs)

Description copied from interface: IRemoteServiceContainerInstantiator

Get the imported config types for a given ContainerTypeDescription for the given exporter supported config types. This method will be called to determine what the local container imported configs are for the given description and exporterSupportedConfigTypes. The local provider can decide which (if any) imported config types should be returned and return them.

As an example, consider the config types for the ECF generic provider. A generic server has a config type of 'ecf.generic.server', and the client has 'ecf.generic.server'. If the generic server exports a given service, the exportersSupportedConfigTypes will be '[ecf.generic.server]'. When this method is called with the ecf.generic.client description (i.e. the container type description named 'ecf.generic.client'), it should respond with a non-null, non-empty array...e.g.: [ecf.generic.client]. This indicates that the ecf.generic.client can serve as an importer for the given exporter config type. All, other descriptions should return null, to indicate that they cannot import a remote service exported by the given exporterSupportedConfigTypes.

Specified by:

getImportedConfigs in interface IRemoteServiceContainerInstantiator

Parameters:

description - the container type description under consideration.

exporterSupportedConfigs - the exporter supported config types under consideration.

Returns:

String[] indicating the importer's supported config types. Should be null, unless one or more of the exporterSupportedConfigTypes is recognized for the given description.

getPropertiesForImportedConfigs

public Dictionary getPropertiesForImportedConfigs(ContainerTypeDescription description,
 String[] importedConfigs,
 Dictionary exportedProperties)

Description copied from interface: IRemoteServiceContainerInstantiator

Get the properties associated with the given description, with the given importedConfigTypes, via the given exportedProperties.

Specified by:

getPropertiesForImportedConfigs in interface IRemoteServiceContainerInstantiator

Parameters:

description - the container type description under consideration.

importedConfigs - the imported config types for the given properties. Will not be null, and should be the same values as returned from IRemoteServiceContainerInstantiator.getImportedConfigs(ContainerTypeDescription, String[]).

exportedProperties - the properties from the exported service. Will not be null.

Returns:

Dictionary that has all of the properties for the importedConfigTypes. May be null if no properties are associated with the given description, importedConfigTypes, exportedProperties.

createInstance

public abstract IContainer createInstance(ContainerTypeDescription description,
 Map<String,?> parameters)
                                   throws ContainerCreateException

Throws:

ContainerCreateException

createInstance

public IContainer createInstance(ContainerTypeDescription description,
 Object[] parameters)
                          throws ContainerCreateException

Description copied from interface: IContainerInstantiator

Create 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:

createInstance in interface IContainerInstantiator

Overrides:

createInstance in class BaseContainerInstantiator

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.

Throws:

ContainerCreateException - thrown if instance cannot be created

throwCreateException

protected IContainer throwCreateException(String message,
 Throwable cause)
                                   throws ContainerCreateException
