Method Detail

get

public RippleValue get(RDFValue rdf)

Maps an RDF value into Ripple space.

Parameters:

rdf - a wrapped RDF value to map into Ripple space

Returns:

a native data structure which is equated with the given RDF value. If there is no such data structure, the value itself. This method will never return null.

put

public void put(org.openrdf.model.Value key,
       RippleValue value)

Adds a new pair to the map.

Parameters:

key - a value in RDF space

value - a corresponding value in Ripple space

add

public void add(RippleValue v,
       ModelConnection mc)
         throws RippleException

Adds a value to the map, binding its associated RDF value back to the Ripple value.

Parameters:

v - the Ripple value to add

mc - a transactional connection

Throws:

RippleException - if the associated RDF value of the Ripple value can't be determined

remove

public void remove(org.openrdf.model.Value key)

Removes a value from the map.

Parameters:

key - the RDF value to remove

keySet

public Set<org.openrdf.model.Value> keySet()

Returns:

the set of all RDF values in the map
