Import/export of snapshots

[lochel]

Purpose

For proper text view/editing in OMEdit an extension of the snapshot functionality is required. It is necessary to handle complete and partial snapshots. It is also necessary to export/import descriptions of systems and components.

import snapshot

New function signature:

• oms_status_enu_t oms_importSnapshot(const char* ex_cref, const char* snapshot);

The import function can be used to import a complete snapshot (this is already implemented):

• > status = oms_importSnapshot("model", snapshot);

The import function can be used to import a partial snapshot, i.e. a given file:

• > status = oms_importSnapshot("model:resources/signalFilter.xml", snapshot);
• > status = oms_importSnapshot("model.system.component:SystemStructure.ssd", snapshot);

export snapshot

This function is returning the snapshot of the given model or just a partial snapshot, i.e. a specific resource file.

New function signature:

• oms_status_enu_t oms_exportSnapshot(const char* ex_cref, char** snapshot);

It can be used to query a specific file, e.g. resources/signalFilter.xml:

• > status = oms_exportSnapshot("model:resources/signalFilter.xml", &snapshot);

It can be used to query a complete snapshot (without the actual resources, e.g. FMUs) (this is already implemented):

• > status = oms_exportSnapshot("model", &snapshot);

list resources

This new function will return a xml file containing all the resources filename, e.g. ssd files, ssv files, signal filter. It will not contain the components themselves, e.g. no FMU paths.

• oms_status_enu_t listResources(const char* cref, char** contents);
