Method Detail

instance

public static MetafacadeImpls instance()

Returns the shared instance of this class.

Returns:

MetafacadeImpls the shared instance.

setMetafacadeModelNamespace

public void setMetafacadeModelNamespace(String metafacadeModelNamespace)

Sets the current model type to which this instance's metafacade class retrieval should apply.

Parameters:

metafacadeModelNamespace - the namespace that has the metafacade model implementation.

discover

public void discover(String[] metafacadeModelNamespaces)

Discovers and loads all metafacade implementation classes and interfaces in each available namespace registry into each given namespace in the modelTypeNamespaces list. Note that this method must be called before any metafacade implementation classes will be able to be retrieved when calling getMetafacadeClass(String)or getMetafacadeImplClass(String).

Parameters:

metafacadeModelNamespaces - a list of each namespace containing a metafacade model facade implementation.

getMetafacadeClass

public Class getMetafacadeClass(String metafacadeImplClass)

Retrieves the metafacade class from the passed in metafacadeImplClass. Will return a MetafacadeImplsException if a metafacade class can not be found for the metafacadeImplClass

Parameters:

metafacadeImplClass - the name of the metafacade implementation class.

Returns:

the metafacade Class

getMetafacadeImplClass

public Class getMetafacadeImplClass(String metafacadeClass)

Retrieves the metafacade implementation class from the passed in metafacadeClass. Will return a MetafacadeImplsException if a metafacade implementation class can not be found for the metafacadeClass

Parameters:

metafacadeClass - the name of the metafacade class.

Returns:

the metafacade implementation Class
