ModuleDependencyRefset

public ModuleDependencyRefset(Set<ModuleDependencyRow> members,
                      boolean validate)
                       throws ValidationException

Creates a new module dependency reference set.

Requirements:

• All MDRS rows are available (actives and inactives)
• Result is a map of every valid "Version" defined by the supplied rows
• There is a valid Version for every unique combination of moduleId and sourceEffectiveTime
• As per the TIG, sourceEffectiveTime and effectiveTime must be equal in every row
• The sourceEffectiveTime is used to identify the Version-specific set of modules
• targetEffectiveTime is always less-than or equal to (<=) sourceEffectiveTime

Note, while module dependencies are not explicitly required to be transitively consistent by the IHTSDO Specifications (as documented in the TIG), it is implicitly required (at least for Core) by the requirements that the Core is not "changed" by an Extension.

Strategy for loading:

• Gather all (active and inactive) rows
• For each unique (active or inactive) moduleId and sourceEffectiveTime pair:
  • The set of associated referencedComponentId module and targetEffectiveTime pairs makes up the required modules
• Compute the completion (transitive closure) of the dependency relationship

Parameters:

members -

Throws:

ValidationException

Method Detail

getModuleDependencies

public Map<String,Map<String,ModuleDependency>> getModuleDependencies()

Description copied from interface: IModuleDependencyRefset

Returns a Map of root module ids and a Map of IModules indexed by version. Each ModuleDependency represents a versioned module and its dependencies.

Specified by:

getModuleDependencies in interface IModuleDependencyRefset

Returns:
