WRITABLE

public static final Predicate<MetaProperty<?>> WRITABLE

Predicate that the returns true if the given option is writable.

CREATABLE

public static final Predicate<MetaProperty<?>> CREATABLE

Predicate that the returns true if the given option is creatable.

NAME_ORDERING

Ordering on the name of options

Method Details

get

public static <T> MetaProperty<T> get(String name)

contains

public static boolean contains(String theName)

Returns true if there is a option with the given name in the set of all valid Stardog options.

contains

public static boolean contains(MetaProperty<?> theOption)

Returns true if the given option is contained in the set of all valid Stardog options.

allProperties

public static Iterable<MetaProperty<?>> allProperties()

Returns the set of all valid Stardog options.

databaseProperties

public static Iterable<MetaProperty<?>> databaseProperties()

memoryProperties

public static Iterable<MetaProperty<?>> memoryProperties()

diskProperties

public static Iterable<MetaProperty<?>> diskProperties()

indexProperties

public static Iterable<MetaProperty<?>> indexProperties()

configProperties

public static Iterable<ConfigProperty<?>> configProperties(Iterable<MetaProperty<?>> theProperties)

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)

Returns a new option map which contains explicit mappings only from those options that satisfy the given filter.

partition
