Method Detail

getContext

URI getContext()

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)

Returns:

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

getSubject

Resource getSubject()

Specified by:

getSubject in interface TriplePattern

Returns:

URI or BlankNode

getPredicate

URI getPredicate()

Specified by:

getPredicate in interface TriplePattern

Returns:

The URI representing the predicate (property)

getObject

Node getObject()

Specified by:

getObject in interface TriplePattern

Returns:

URI, String, TypedLiteral, LanguageTaggedLiteral or BlankNode

dump

void dump(String[] options)

debug output. Lazy implementation can just do nothing.

Parameters:

options - undocumented :-) Depends on underlying implementation. See source code.

hashCode

int hashCode()

Overrides:

hashCode in class Object

equals

boolean equals(Object other)

Overrides:

equals in class Object
