infoProperties

public static Iterable<InfoProperty<?>> infoProperties(Iterable<MetaProperty<?>> theProperties)

defaults

public static Metadata defaults(Iterable<MetaProperty<?>> theStardogOptions)

Returns a new option map that contains explicit mapping for each given option to its default value.

filter

public static Metadata filter(Metadata theOptions,
                              Predicate<MetaProperty<?>> theFilter)
