StatementImpl

public StatementImpl(URI context,
                     Resource subject,
                     URI predicate,
                     Node object)

builds a new statement

Parameters:

subject - The subject of this statement

predicate - The proerty of this statement

object - The object of this statement

Method Detail

getSubject

public Resource getSubject()

Specified by:

getSubject in interface Statement

Specified by:

getSubject in interface TriplePattern

Returns:

URI or BlankNode

getPredicate

public URI getPredicate()

Specified by:

getPredicate in interface Statement

Specified by:

getPredicate in interface TriplePattern

Returns:

The URI representing the predicate (property)

getObject

public Node getObject()

Specified by:

getObject in interface Statement

Specified by:

getObject in interface TriplePattern

Returns:

URI, String, TypedLiteral, LanguageTaggedLiteral or BlankNode

toString

public String toString()

Overrides:

toString in class Object

getContext

public URI getContext()

Description copied from interface: Statement

Note: this was set to be a Model before, but that would have caused problems, when people accesssed the model via the Statement. (compare to Jena, where graph and Model are separated. We are here on graph level)

Specified by:

getContext in interface Statement

Returns:

the context, where this statement was created. Returns null when not in a ModelSet.

hashCode

public int hashCode()

Specified by:

hashCode in interface Statement

Overrides:

hashCode in class AbstractStatement

equals

public boolean equals(Object other)

Specified by:

equals in interface Statement

Overrides:

equals in class AbstractStatement
