create

public GraphQuery create(Properties props)
Description copied from class: AbstractFactory
Create the given object using the settings in the Properties object. This function is the only global creation object, but each factory should also define a more user-friendly version consisting of a set of commonly used creation parameters as well as a version combining commonly used features with a Properties object. The property may be null. if the creation fails, the factory should log to the Logger the explanation and return null. If at all possible, the factory should provide a reasonable fail-over value rather than return null.

Specified by:
create in class AbstractFactory<GraphQuery>
Parameters:
props - parameters used to control the factory.
Returns:
newly created object or null
