Method Details

getAttributeDescriptor

public Descriptor getAttributeDescriptor(FieldSpecification<?,?> attribute)

Description copied from interface: Descriptor

Gets descriptor for the specified attribute.

Specified by:

getAttributeDescriptor in interface Descriptor

Overrides:

getAttributeDescriptor in class FieldDescriptor

Parameters:

attribute - Entity attribute, as specified by the application metamodel

Returns:

Descriptor

getAttributeContexts

public Set<URI> getAttributeContexts(FieldSpecification<?,?> attribute)

Description copied from interface: Descriptor

Gets contexts in which the property assertion(s) of the specified attribute are stored.

If none are specified for the attribute, contexts of this descriptor are returned.

Note that for saving a property assertion, there must be at most one context.

Specified by:

getAttributeContexts in interface Descriptor

Overrides:

getAttributeContexts in class FieldDescriptor

Parameters:

attribute - Entity attribute, as specified by the application model

Returns:

Context identifiers

addAttributeDescriptor

public ObjectPropertyCollectionDescriptor addAttributeDescriptor(FieldSpecification<?,?> attribute,
 Descriptor descriptor)

Description copied from interface: Descriptor

Adds descriptor for the specified attribute.

If a descriptor already exists for the specified attribute, it is overridden by the new one.

Specified by:

addAttributeDescriptor in interface Descriptor

Overrides:

addAttributeDescriptor in class FieldDescriptor

Parameters:

attribute - The attribute to set descriptor for

descriptor - The descriptor to use

Returns:

This instance

addAttributeContext

public ObjectPropertyCollectionDescriptor addAttributeContext(FieldSpecification<?,?> attribute,
 URI context)

Description copied from interface: Descriptor

Adds repository context for the specified attribute.

This in effect means creating a descriptor (if it does not already exist) for the specified field and adding the specified context to it.

Specified by:

addAttributeContext in interface Descriptor

Overrides:

addAttributeContext in class FieldDescriptor

Parameters:

attribute - The attribute to set context for

context - The context to set

Returns:

This instance

See Also:

• Descriptor.addAttributeDescriptor(FieldSpecification, Descriptor)

addContext

public Descriptor addContext(URI context)

Description copied from interface: Descriptor

Adds the specified context to this descriptor.

Note that adding the default context removes all the previously added contexts, as they become obsolete.

Specified by:

addContext in interface Descriptor

Overrides:

addContext in class AbstractDescriptor

Parameters:

context - Context to add, null indicates default context

Returns:

This instance

overridesAssertionContext

public boolean overridesAssertionContext()

Description copied from interface: Descriptor

Whether this descriptor overrides assertion context.

Assertions are typically stored in the subject context, even if their target is in a different context (see Descriptor.areAssertionsInSubjectContext()). However, literal values have to be stored in the assertion context only, so descriptors of fields holding literal values can override the default assertion target context to use the field descriptor context for assertion as well.

Specified by:

overridesAssertionContext in interface Descriptor

Overrides:

overridesAssertionContext in class FieldDescriptor

Returns:

Boolean indicating whether assertion context is based on object descriptor

See Also:

• Descriptor.areAssertionsInSubjectContext()

unwrap

public EntityDescriptor unwrap()

Description copied from interface: Descriptor

Unwraps this descriptor if it wraps another descriptor (such as in the case of a collection descriptor).

If there is nothing to unwrap, the descriptor returns itself.

Returns:

Unwrapped descriptor

copy

public ObjectPropertyCollectionDescriptor copy()

Description copied from interface: Descriptor

Creates a copy of this descriptor.

Specified by:

copy in interface Descriptor

Overrides:

copy in class FieldDescriptor

Returns:

New descriptor with identical values

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractDescriptor

equals

protected boolean equals(Object other,
 Map<AbstractDescriptor.VisitedPair,Boolean> visited)

Overrides:

equals in class FieldDescriptor

hashCode

protected int hashCode(Map<Object,Boolean> visited)

Overrides:

hashCode in class FieldDescriptor
