public GeoSpatialServiceFactory()

Method Detail

getServiceOptions

public BigdataNativeServiceOptions getServiceOptions()

Description copied from interface: ServiceFactory

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

create

public BigdataServiceCall create(ServiceCallCreateParams createParams)

Description copied from interface: ServiceFactory

Create a service invocation object.

Parameters:

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

Returns:

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

getRequiredBound

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

Description copied from class: AbstractServiceFactoryBase

Default implementation for method ServiceFactory.getRequiredBound(ServiceNode), allowing for simple services where all variables used inside the service are considered "outgoing". As a consequence, when building upon this default implementation, the Service will be executed *before* the variables used inside the Service body are bound.

Specified by:

getRequiredBound in interface ServiceFactory

Overrides:

getRequiredBound in class AbstractServiceFactoryBase
