Method Detail

add

public int add(String varName,
               Value value)

add

public int add(String varName,
               RDFNode node)

setQuery

public void setQuery(Query q)

addTriple

public void addTriple(Statement s)

Add a triple to the ResultBindingImpl. Assumed to be related to the some binding of this result binding.

getTriples

public Set getTriples()

Get the set of statements that caused this ResultBindingImpl. Note: returns a set so there may be less statements in some result bindings than in others and there may be less than the number of triple patterns in the query.

Specified by:

getTriples in interface ResultBinding

mergeTriples

public Model mergeTriples(Model model)

Merge the triples that caused this result binding into a model.

Specified by:

mergeTriples in interface ResultBinding

Returns:

The model passed in

names

public Iterator names()

Description copied from interface: ResultBinding

Iterator over the names in this binding

Specified by:

names in interface ResultBinding

iterator

public ResultBindingIterator iterator()

Description copied from interface: ResultBinding

Return an iterator of the items in this result binding. This iterator has operations to access the current variable name and variable value.

Specified by:

iterator in interface ResultBinding

Returns:

ResultBindingIterator

get

public Object get(String varName)

Description copied from interface: ResultBinding

Return the value of the named variable in this binding. Object will be an RDFNode.

Specified by:

get in interface ResultBinding

size

public int size()

check

public void check()

toString

public String toString()

Overrides:

toString in class Object
