tupleToBinding

public static <T>
org.apache.jena.sparql.engine.binding.Binding tupleToBinding(org.aksw.commons.tuple.bridge.TupleBridge<T,org.apache.jena.graph.Node> accessor,
 T pattern,
 T assignment)

Create a binding from two tuples, the first acting as a pattern and the second as the source of values for assignment to the pattern's variables. In essence, the resulting binding is created by pairing up the components of the tuples: binding.add(pattern[i], assigment[i]). If a concrete node of the pattern is paired with a non-equivalent node then null is returned.

Type Parameters:

T - The tuple type.

Parameters:

accessor - The tuple accessor (components must be Nodes)

pattern - The tuple pattern (may contain variables)

assignment - The tuple used to assign values to the variables (should not contain variables)

Returns:

A binding or null.
