public interface ServiceFactory

Factory for creating objects which can talk to SPARQL service end points.

Method Summary

Methods

Modifier and Type	Method and Description
ServiceCall<?>	create(ServiceCallCreateParams params) Create a service invocation object.
Set<IVariable<?>>	getDesiredBound(ServiceNode serviceNode) Returns, for the given service node, the variables that are desired to be bound prior to start executing the service.
Set<IVariable<?>>	getRequiredBound(ServiceNode serviceNode) Returns, for the given service node, the variables that must be bound prior to start executing the service.
IServiceOptions	getServiceOptions() Return options for the service end point.

Method Detail

getServiceOptions

IServiceOptions getServiceOptions()

Return options for the service end point. Depending on the implementation, these options MAY be configurable.

create

ServiceCall<?> create(ServiceCallCreateParams params)

Create a service invocation object.

Parameters:

params - The pararameters, which are encapsulated by this interface.

Returns:

The object which can be used to evaluate the SERVICE clause.

getRequiredBound

Set<IVariable<?>> getRequiredBound(ServiceNode serviceNode)

Returns, for the given service node, the variables that must be bound prior to start executing the service. This information is important to reason about the position where to place the service within the execution proccess. See IVariableBindingRequirements.getRequiredBound(StaticAnalysis).

getDesiredBound

Set<IVariable<?>> getDesiredBound(ServiceNode serviceNode)

Returns, for the given service node, the variables that are desired to be bound prior to start executing the service. This information is important to reason about the position where to place the service within the execution proccess. See IVariableBindingRequirements.getDesiredBound(StaticAnalysis).
