Method Detail

isDftGraph

public static boolean isDftGraph(java.lang.String graphName)

Is this a name for the default graph prefix set?

isDftGraph

public static boolean isDftGraph(Node graphName)

Is this a name node for the default graph prefix set?

prefix

public static java.lang.String prefix(java.lang.String prefix)

Canonical prefix - remove a trailing ":". The return is not null.

findByURI

public static java.lang.String findByURI(PrefixMap pmap,
                                         java.lang.String uriStr)

Reverse lookup of URI to a prefix. General implementation by scanning the PrefixMap. Returns a prefix if found or null. If several prefixes for the same URI, returns one at random.

Provide, via an adapter if necessary, the PrefixMap for a Graph.

adapt

public static PrefixMapping adapt(PrefixMap prefixMap)

Apply a wrapper to a PrefixMap to provide the PrefixMapping API.

adapt

public static PrefixMap adapt(PrefixMapping prefixMapping)

Apply a wrapper to a PrefixMapping to provide the PrefixMap API.

toString

public static java.lang.String toString(PrefixMap prefixMap)

Calculate a printable multi-line string.
