Class SPINThreadPropertyFunctionRegistry

java.lang.Object

org.apache.jena.sparql.pfunction.PropertyFunctionRegistry

org.topbraid.spin.arq.SPINThreadPropertyFunctionRegistry

public class SPINThreadPropertyFunctionRegistry
extends org.apache.jena.sparql.pfunction.PropertyFunctionRegistry

An ARQ PropertyFunctionRegistry that can be used to associate functions with Threads, so that additional functions from a given Model can be made visible depending on the SPARQL query thread. Note that this concept only works if ARQ has been set to single threading, which is done by the static block below. The contract of this class is very strict to prevent memory leaks: Users always need to make sure that unregister is called as soon as a query (block) ends.
