The list of such extensions is available by calling Property.getInstanceProperties(). The values of these properties are available by calling Property.get(Property). For more details, see Section 3.5.6.

getInstanceProperties

public List getInstanceProperties()

Description copied from interface: Property

Returns a read-only List of instance Properties available on this Property.

This list includes, at a minimum, any open content properties (extensions) added to the object before defining the Property's Type. Implementations may, but are not required to in the 2.1 version of SDO, provide additional instance properties.

Specified by:

getInstanceProperties in interface Property

Returns:

the List of instance Properties on this Property.

Returns a list of alias names for this Property.

Specified by:

the opposite Property if the Property is bi-directional or null

getType

public Type getType()

Returns the type of the Property.

Specified by:

getType in interface Property

Returns:

the Property type.

isContainment

public boolean isContainment()

Returns whether the Property is containment, i.e., whether it represents by-value composition. 3.1.6 Containment ...The tree structure is created using containment references which start at the root DataObject. The root DataObject refers to other DataObjects, which can refer to further DataObjects. Each DataObject in the data graph, except for the root DataObject, must have a containment reference from another node in the tree. Each DataObject in the graph keeps track of the location of its containment reference. ... A container DataObject is one that contains other DataObjects. A DataObject can have a maximum of one container DataObject. If a DataObject has no container, it is considered to be a root DataObject. In the case of a reference, a Property may be either a containment or non-containment reference. In EMOF, the term containment reference is called composite. In XML, elements with complex types are mapped to containment properties. S.C. indicates how to emit XML entities in terms of containment. E.g. in UML, Package.packagedElement is a containment reference property. Activity.edge is a reference property.

Specified by:

isContainment in interface Property

Returns:

true if the Property is containment.

getContainingType

public Type getContainingType()

Returns the containing type of this Property.

Specified by:

getContainingType in interface Property

Returns:

the Property's containing type.

See Also:

Type.getProperties()

isMany

public boolean isMany()

Returns whether the Property is many-valued.

Specified by:

isMany in interface Property

Returns:

true if the Property is many-valued.

isNullable

public boolean isNullable()

Returns whether or not instances of this property can be set to null. The effect of calling set(null) on a non-nullable property is not specified by SDO.

Specified by:

isNullable in interface Property

Returns:

true if this property is nullable.

isOpenContent

public boolean isOpenContent()

Returns whether or not this is an open content Property.

Specified by:

isOpenContent in interface Property

Returns:

true if this property is an open content Property.

isReadOnly

public boolean isReadOnly()

Returns true if values for this Property cannot be modified using the SDO APIs. When true, DataObject.set(Property property, Object value) throws an exception. Values may change due to other factors, such as services operating on DataObjects.

Specified by:

isReadOnly in interface Property

Returns:

true if values for this Property cannot be modified.

toString

public String toString()

Overrides:

toString in class Object
