Method Detail

getAnnotation

public org.openrdf.model.Value getAnnotation(org.openrdf.model.URI predicate)

Description copied from interface: Edge

Get an annotation property of this edge.

Specified by:

getAnnotation in interface Edge

Parameters:

predicate - The predicate that identifies the annotation whose value is to be returned.

Returns:

The value of the specified annotation property. If the specified annotation property has multiple values, a ValueSet that contains all of the values will be returned. Otherwise, a single discrete value will be returned, or null if there is no value for the specified annotation.

setAnnotation

public Edge setAnnotation(org.openrdf.model.URI predicate,
                          org.openrdf.model.Value value)

Description copied from interface: Edge

Set an annotation property of this edge. This method overwrites any previous value for the annotation property. If the previous value was a ValueSet, then the entire set is replaced with the supplied value.

Specified by:

setAnnotation in interface Edge

Parameters:

predicate - The predicate that identifies the annotation property to be set

value - The value of the annotation property to be set.

removeAnnotation

public org.openrdf.model.Value removeAnnotation(org.openrdf.model.URI predicate)

Description copied from interface: Edge

Remove the specified annotation property from the Edge. If the current value is a ValueSet, the entire set of values is removed.

Specified by:

removeAnnotation in interface Edge

Parameters:

predicate - The predicate that names the annotation to be removed

Returns:

The value of the annotation property that was removed, or null if there was no such annotation property.

copyAnnotations

public void copyAnnotations(Edge edge)

Description copied from interface: Edge

Copy the annotation properties from another edge into this Edge.

Specified by:

copyAnnotations in interface Edge

Parameters:

edge - The edge from which annotations will be copied

getAnnotationSet

public ValueSet getAnnotationSet(org.openrdf.model.URI predicate)

Description copied from interface: Edge

Get the values of a specific annotation property as a ValueSet.

Specified by:

getAnnotationSet in interface Edge

Parameters:

predicate - The predicate that names the annotation property

Returns:

A ValueSet containing all the values of the specified annotation. If there are no such values an empty set is returned.

addAnnotation

public Edge addAnnotation(org.openrdf.model.URI predicate,
                          org.openrdf.model.Value value)

Description copied from interface: Edge

Add an annotation value to the Edge.

Specified by:

addAnnotation in interface Edge

Parameters:

predicate - The predicate that names the annotation property

value - The value of the annotation property.

Returns:

This edge.

matches

public boolean matches(org.openrdf.model.Value a,
                       org.openrdf.model.Value b)

Description copied from interface: Edge

A convenience function which tests whether two values are equal, or one is contained in the other.

Specified by:

matches in interface Edge

Parameters:

a - A discrete Value (Resource or Literal) or a ValueSet

b - Another discrete Value (Resource or Literal) or a ValueSet

Returns:

True if a and b are equal, or a is contained in b, or b is contained in a.
