Method Detail

services

public abstract Enumeration services()

Get all available services managed by the engine.

Returns:

an enumeration of ServiceTypes

services

public Enumeration services(Class clazz)

Get all available services that are assignable to the given superclass.

Parameters:

clazz - the class that all services should be subclass of

getServiceTypes

public abstract List getServiceTypes()

Getter for list of all service types.

Returns:

a list of ServiceTypes

setServiceTypes

public abstract void setServiceTypes(List arr)

Setter for list of service types. This permits changing instances of the objects but only within the types that are already registered in the system by manifest sections. If an instance of any other type is in the list it is ignored.

Parameters:

arr - a list of ServiceTypes

find

public ServiceType find(Class clazz)

Find the service type implemented as a given class. The whole registry is searched for a service type of that exact class (subclasses do not count).

This could be used during (de-)serialization of a service type: only store its class name and then try to find the type implemented by that class later.

Parameters:

clazz - the class of the service type looked for

Returns:

the desired type or null if it does not exist

find

public ServiceType find(String name)

Find a service type of a supplied name in the registry.

This could be used during (de-)serialization of a service type: only store its name and then try to find the type later.

Parameters:

name - (display) name of service type to find

Returns:

the desired type or null if it does not exist
