Methods

| Improve this Doc View Source

Add(Triple)

Adds a Triple to the Collection.

Declaration

protected abstract bool Add(Triple t)

Parameters

Type	Name	Description
Triple	t	Triple to add.

Returns

Type	Description
System.Boolean

Remarks

Adding a Triple that already exists should be permitted though it is not necessary to persist the duplicate to underlying storage.

| Improve this Doc View Source

Contains(Triple)

Determines whether a given Triple is asserted in the Triple Collection.

Declaration

public abstract bool Contains(Triple t)

Parameters

Type	Name	Description
Triple	t	The Triple to test.

Returns

Type	Description
System.Boolean	True if the triple exists as an asserted triple in the collection.

Remarks

Designed to allow the underlying storage of a Triple Collection to be changed at a later date without affecting classes that use it.

| Improve this Doc View Source

ContainsQuoted(Triple)

Determines whether a given triple is quoted by a triple node of a triple in the collection.

Declaration

public abstract bool ContainsQuoted(Triple t)

Parameters

Type	Name	Description
Triple	t	The triple to test.

Returns

Type	Description
System.Boolean	True if the triple is quoted in the triple collection, false otherwise.

Remarks

Designed to allow the underlying storage of a Triple Collection to be changed at a later date without affecting classes that use it.

| Improve this Doc View Source

Delete(Triple)

Deletes an asserted triple from the collection.

Declaration

protected abstract bool Delete(Triple t)

Parameters

Type	Name	Description
Triple	t	Triple to remove.

Returns

Type	Description
System.Boolean	True if the operation removed an asserted triple from the collection, false otherwise.

Remarks

Deleting a triple that is not asserted in the collection should have no effect and give no error. Quoted triples cannot be removed from the collection via this method - instead they should be automatically removed when all asserted triples that reference them are removed. Deleting a triple that is both asserted and quoted will remove the assertion of the triple (and return true), but the triple will remain in the collection as a quoted triples.
