Create ITypes interface for meta-work with model.

[jmoore]

A service is needed for working with the model at a meta-level and perhaps working with the meta-model (ha ha).

See http://cvs.openmicroscopy.org.uk/tiki/tiki-index.php?page=ApiRequestsOMERO for use cases.

Other possible methods include:

• IEnum iTypes.enum( Class k, String value )
• Permissions iTypes.permissions( Class k )

Originally : http://bugs.openmicroscopy.org.uk/show_bug.cgi?id=656

[jmoore]

See Omero3Connector#L346 for an example of iType.getEnum.

Also:

• List<E> itype.allEnumerations( Class<E extends IEnum> k);
• E itype.getEnumeration( Class<E extends IEnum> k, String string );

(The generic representations are dependent on #96 for reworking the model; and #140 for defining IEnum.)

[jmoore]

Needed for #52 (multiple annotations).

[jmoore]

ITypes has been created in skeletal form in r704, but is not implemented. It was interestingly, not needed for #52, and actually won't be needed for #156 either, so I'm moving this back out of iteration3.

[jmoore]

r765 (properly) generified the ITypes interface while r768 started using the for login. Several methods within BasicSecuritySystem (r768) should eventually be refactored into ITypes

[jmoore]

r816 adds createEnumeration

[jmoore]

ITypes should provide access to ExtendedMetadata, added in r921 for #337. Rescheduling with the SecuritySystem reworking (#328)

[jmoore]

May also be able to remove PostProcessInjector.

[jmoore]

Not done during the reworking. But rescheduling for M4. It will eventually be useful to make these operations public.

There were also several suggestions during the Paris mtg, such as:

• Class[][] getHierarchies()
