Instrument Data Service

From MantidProject

What is it?

The Instrument Data Service (IDS) is a Data Service that is specialized to hold all of the instruments that are created during a user session. Whenever an instrument definition is loaded it is saved in the IDS and further workspaces that refer to the same instrument share the same definition.

Extracting an instrument from the Instrument Data Service

This is rarely something that a user or an algorithm writer would need to do as it is all handled by the framework internals. Normally you would access the instrument relating to a workspace directly though that workspace.

workspace->getInstrument();

However if you really did want to access the instrument from the IDS (as a Shared Pointer), although this would then lack any workspace specific alterations or properties.

boost::shared_ptr<Instrument> intrument = workspace->getInstrument();
