Interface Summary

IAttribute	As defined at (TODO (Doc): add reference), This interface represents an attribute of an Entity.
IAttributeValue	Holds the value of an attribute.
IAuthNAttributesMaterials	Represents an authentication identity to be used when calling IContext.open(Object) This type of identity is comprised of a set of attributes which make up the materials used in authentication.
IComplexAttrValue
IComplexMetaValue	Represents a complex metadata value.
IContext	As defined at http://spwiki.editme.com/Context and http://spwiki.editme.com/ContextProvider, This interface holds a set of IEntity objects.
IContextFactory	As defined at http://spwiki.editme.com/ContextProvider#ContextFactory, This interface is implemented by IdAS context providers so that their IContext instances may be instantiated.
IContextId
IContextRelation	Represents a relationship to another IContext.
IEntity	As defined at http://wiki.eclipse.org/Entity and http://wiki.eclipse.org/Context, This interface holds a set of IEntity objects.
IFilter	A filter is either an assertion, or an operator plus a set of filters.
IFilterAssertion	Represents a filter assertion.
IFilterAttributeAssertion	Represents a filter assertion about a Entity's Attributes (IHasAttributes.getAttribute(URI) and IHasAttributes.getAttributes()).
IFilterEntityIDAssertion	Represents a filter assertion about a Entity's ID (see IEntity.getEntityID()).
IFilterEntityTypeAssertion	Represents a filter assertion about an Entity's Type (see IEntity.getEntityType()).
IFilterMetadataAssertion	Represents a filter assertion about metadata. This assertion is made up of a comparator (operator), metadataID and assertion value.
IHasAttributes
IHasMetadata	Extended by interfaces which have metadata associated with them.
IMetadata	TODO (Doc): Add (or point to) doc which explains what metadata is and how it's used
IMetadataValue	Holds the value of a metadata element.
ISimpleAttrValue
ISimpleMetaValue
ISingleValuedAttribute
ITypedValue

Exception Summary

AuthenticationException	Thrown when an attempt to authenticate has failed.
BadFilterException
ContextNotOpenException	Thrown when methods requiring an open Context are called on a non-open Context.
ContextOpenException	Thrown when IContext.open() is called on an already open context.
EntityExistsException
IdASException	Root IdAS Exception class
InvalidEntityIDException	Thrown when a specified Type is invalid.
InvalidTypeException	Thrown when a specified Type is invalid.
MultipleValuesExistException	Thrown in cases where an attribute is expected to have a single value but doesn't.
NoSuchEntityException	Thrown when a specified Entity is not found in the Context.
NotImplementedException	Thrown when the method being called has not been implemented by the context provider.
NotSingleValuedAttributeException	Thrown in cases where an attribute's model specifies that the attribute may hold multiple values and the caller expects the attribute to be restricted to a single value (and thus castable to ISingleValuedAttribute.
ValueAlreadyExistsException	Thrown in cases where a value is being added to an attribute and that value already exists.
