Method Detail

get

public static <T> MetaProperty<T> get(java.lang.String name)

contains
```
public static boolean contains(java.lang.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 java.lang.Iterable<MetaProperty<?>> allProperties()

Returns the set of all valid Stardog options.

databaseProperties

public static java.lang.Iterable<MetaProperty<?>> databaseProperties()

memoryProperties

public static java.lang.Iterable<MetaProperty<?>> memoryProperties()

diskProperties

public static java.lang.Iterable<MetaProperty<?>> diskProperties()

indexProperties

public static java.lang.Iterable<MetaProperty<?>> indexProperties()

configProperties

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

infoProperties

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

defaults
```
public static Metadata defaults(java.lang.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,
                              java.util.function.Predicate<MetaProperty<?>> theFilter)

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

partition

public static com.complexible.stardog.metadata.PartitionedMetadata partition(Metadata theOptions,
                                                                             java.util.function.Predicate<MetaProperty<?>> theFilter,
