Constructor Detail

ArrayBindingSet

public ArrayBindingSet(String... names)

Creates a new Array-based BindingSet for the supplied bindings names. The supplied list of binding names is assumed to be constant; care should be taken that the contents of this array doesn't change after supplying it to this solution.

Parameters:

names - The binding names.

ArrayBindingSet

public ArrayBindingSet(BindingSet toCopy,
                       Set<String> names,
                       String[] namesArray)

ArrayBindingSet

public ArrayBindingSet(ArrayBindingSet toCopy,
                       String... names)

Method Detail

getDirectSetBinding

public BiConsumer<org.eclipse.rdf4j.model.Value,ArrayBindingSet> getDirectSetBinding(String bindingName)

This is used to generate a direct setter into the array to put a binding value into. Can be used to avoid many comparisons to the bindingNames.

Parameters:

bindingName - for which you want the setter

Returns:

the setter biconsumer which can operate on any ArrayBindingSet but should only be used on ones with an identical bindingNames array. Otherwise returns null.

getDirectAddBinding

public BiConsumer<org.eclipse.rdf4j.model.Value,ArrayBindingSet> getDirectAddBinding(String bindingName)

getDirectGetBinding

public Function<ArrayBindingSet,Binding> getDirectGetBinding(String bindingName)
