org.apache.hivemind.schema
Interface Schema

All Superinterfaces:: org.apache.hivemind.parse.AnnotationHolder, org.apache.hivemind.Locatable

public interface Schema
extends org.apache.hivemind.parse.AnnotationHolder, org.apache.hivemind.Locatable

An object which may contain a model, used to identify the form of XML content allowed within some other, containing element.

This is very much provisional; in the future will be more control for validation (i.e, controlling the number of occurances), and support for analogs of W3C SChema sequence and choice. The excess flexibility here forces some validation into element objects (the objects created from the Rules within the ElementModels).

Method Summary

boolean canInstancesBeKeyed()
          Returns true if Elements conforming to this Schema can be indexed using a key.

org.apache.hivemind.internal.Module getDefiningModule()
          Return the Module in which the Schema was defined.

java.util.List getElementModel()
          Returns a List of ElementModel, identifing the elements which may be enclosed by the modeled element.

java.lang.String getId()
          Returns the (unqualified) id of this schema.

boolean visibleToModule(java.lang.String moduleId)
          Returns true if the schema is visible to the specified module, false otherwise.

The returned list is unmodifiabled and may be empty, but won't be null.

canInstancesBeKeyed

public boolean canInstancesBeKeyed()

Returns true if Elements conforming to this Schema can be indexed using a key. For this to be true every top-level ElementModel 55 must define a non-null key attribute 55 .

Since:: 1.1

visibleToModule

public boolean visibleToModule(java.lang.String moduleId)

Returns true if the schema is visible to the specified module, false otherwise.

Since:: 1.1
