Re: [higgins-dev] [IdAS] use cases
|
The answer to my question (below) is "no". The attribute is attached
to a specific service.algorithm pair, so using a generic "higgins"
algorithm won't work. (There could only be type of ContextFactory
service in a provider. That's a restriction we don't need and
presumably don't want.)
Instead, Providers can use whatever name they want for the algorithm.
If the user knows the name of a particular ContextFactory algorithm,
then they can use it. Otherwise, they can search the DataFormats
attribute to find the format they want.
As an example, I just created a HigginsProvider that has two
ContextFactory services:
ContextFactory.LDAP DataFormats:LDAP
ContextFactory.Super DataFormats:LDAP:RDF:SQL
...Greg
Context is a service type (abstract class), and its algorithm string
is its URI
-- an attribute "FactoryClass" specifies the class name of the
ContextFactory that creates this type of context
-- static method getInstance(URI) to create a Context object via a
particular provider and factory
-- Question: Is a provider allows to have several services with the
same algorithm, but different attributes?
