Constructor Detail

PropertyValue

public PropertyValue(PredicateNode p,
                     ObjectNode o)

Create a new property value.

Parameters:

p - The property.

o - The value.

PropertyValue

public PropertyValue(Node p,
                     Node o)

Create a new triple. This is an overloaded version of the first constructor accepting Nodes instead of the more specific types. Consequently, this method can throw a ClassCastException if the wrong types are provided.

Parameters:

p - The predicate.

o - The object.

Throws:

ClassCastException - If an incompatible type is provided in p or o.

PropertyValue

public PropertyValue(Pair<PredicateNode,ObjectNode> pair)

Create a new property value.

Parameters:

pair - The generalized property value.

PropertyValue

public PropertyValue(PredicateNode p,
                     String o)

Create a new property value with a string literal.

Parameters:

p - The property.

o - The object.
