IndexingMatcher

public IndexingMatcher(boolean s,
                       boolean p,
                       boolean o,
                       boolean c,
                       com.tinkerpop.blueprints.oupls.sail.GraphSail.DataStore store)

Create a new indexing matcher based on the given triple pattern.

Parameters:

s - whether the subject is specified

p - whether the predicate is specified

o - whether the object is specified

c - whether the context is specified

store - the Blueprints data store

Method Detail

match

public Iterable<Edge> match(org.openrdf.model.Resource subject,
                            org.openrdf.model.URI predicate,
                            org.openrdf.model.Value object,
                            org.openrdf.model.Resource context)

Description copied from class: Matcher

Retrieve matching statements based on this matcher's triple pattern as well as the provided values. If a component such as subject or object is specified in the pattern, a non-null value must be provided to this method. Non-null values for unspecified components may be provided, but they will not be used.

Specified by:

match in class Matcher

Parameters:

subject - the subject value of matching statements

predicate - the predicate value of matching statements

object - the object of matching statements

context - the context of matching statements

Returns:

an iterator over all matching statements

indexStatement

public void indexStatement(Edge statement,
                           org.openrdf.model.Resource subject,
                           org.openrdf.model.URI predicate,
                           org.openrdf.model.Value object,
                           String context)

Index a statement using this Matcher's triple pattern. The subject, predicate, object and context values are provided for efficiency only, and should agree with the corresponding values associated with the graph structure of the edge.

Parameters:

statement - the edge to index as an RDF statement

subject - the subject of the statement

predicate - the predicate of the statement

object - the object of the statement

context - the context of the statement
