Example 1 with QueryBindingSet

use of org.eclipse.rdf4j.query.algebra.evaluation.QueryBindingSet in project incubator-rya by apache.

the class BindingSetStringConverter method convert.

@Override
public BindingSet convert(final String bindingSetString, final VariableOrder varOrder) {
    requireNonNull(bindingSetString);
    requireNonNull(varOrder);
    // If both are empty, return an empty binding set.
    if (bindingSetString.isEmpty() && varOrder.toString().isEmpty()) {
        return new MapBindingSet();
    }
    // Otherwise parse it.
    final String[] bindingStrings = bindingSetString.split(BINDING_DELIM);
    final String[] varOrderArr = varOrder.toArray();
    checkArgument(varOrderArr.length == bindingStrings.length, "The number of Bindings must match the length of the VariableOrder.");
    final QueryBindingSet bindingSet = new QueryBindingSet();
    for (int i = 0; i < bindingStrings.length; i++) {
        final String bindingString = bindingStrings[i];
        if (!NULL_VALUE_STRING.equals(bindingString)) {
            final String name = varOrderArr[i];
            final Value value = toValue(bindingStrings[i]);
            bindingSet.addBinding(name, value);
