Method Details

getResult

public Collection<org.apache.jena.sparql.algebra.Op> getResult()

Get the set of encountered ops

Returns:

collect

public static Set<org.apache.jena.sparql.algebra.Op> collect(org.apache.jena.sparql.algebra.Op start,
 boolean skipService)

Parameters:

start - The starting Op

skipService - If true then internally use Transformer.transformSkipService(org.apache.jena.sparql.algebra.Transform, Op) instead of Transformer.transform(org.apache.jena.sparql.algebra.Transform, Op)

Returns:
