SubjectAreaProjectHandler

public SubjectAreaProjectHandler(OMRSAPIHelper oMRSAPIHelper,
                                 int maxPageSize)

Construct the Subject Area Project Handler needed to operate within a single server instance.

Method Detail

createProject

public SubjectAreaOMASAPIResponse<Project> createProject(String userId,
                                                         Project suppliedProject)

Create a Project. There are specializations of projects that can also be created using this operation. To create a specialization, you should specify a nodeType other than Project in the supplied project.

Projects with the same name can be confusing. Best practise is to createProjects that have unique names. This Create call does not police that project names are unique. So it is possible to create Projects with the same name as each other.

Valid nodeTypes for this request are:

• Taxonomy to create a Taxonomy
• CanonicalProject to create a canonical project
• TaxonomyAndCanonicalProject to create a project that is both a taxonomy and a canonical project
• Project to create a project that is not a taxonomy or a canonical project

Parameters:

userId - unique identifier for requesting user, under which the request is performed

suppliedProject - Project to create

Returns:

response, when successful contains the created project. when not successful the following Exception responses can occur

• UserNotAuthorizedException the requesting user is not authorized to issue this request.
• MetadataServerUncontactableException not able to communicate with a Metadata respository service.
• InvalidParameterException one of the parameters is null or invalid.
• UnrecognizedGUIDException the supplied guid was not recognised.
• ClassificationException Error processing a classification.
• StatusNotSupportedException A status value is not supported.

public SubjectAreaOMASAPIResponse<Project> getProjectByGuid(String userId,
                                                            String guid)

Get a project by guid.

Parameters:

userId - unique identifier for requesting user, under which the request is performed

guid - guid of the project to get

Returns:

response which when successful contains the project with the requested guid when not successful the following Exception responses can occur

• UserNotAuthorizedException the requesting user is not authorized to issue this request.
• MetadataServerUncontactableException not able to communicate with a Metadata respository service.
• InvalidParameterException one of the parameters is null or invalid.
• UnrecognizedGUIDException the supplied guid was not recognised

public SubjectAreaOMASAPIResponse<Project> findProject(String userId,
                                                       FindRequest findRequest)

Find Project

Parameters:

userId - unique identifier for requesting user, under which the request is performed

findRequest - FindRequest

Returns:

A list of Projects meeting the search Criteria

• UserNotAuthorizedException the requesting user is not authorized to issue this request.
• MetadataServerUncontactableException not able to communicate with a Metadata respository service.
• InvalidParameterException one of the parameters is null or invalid.
• FunctionNotSupportedException Function not supported this indicates that a find was issued but the repository does not implement find functionality in some way.

getProjectRelationships

public SubjectAreaOMASAPIResponse<Line> getProjectRelationships(String userId,
                                                                String guid,

updateProject

public SubjectAreaOMASAPIResponse<Project> updateProject(String userId,
                                                         String guid,

Update a Project

If the caller has chosen to incorporate the project name in their Project Terms or Categories qualified name, renaming the project will cause those qualified names to mismatch the Project name. If the caller has chosen to incorporate the project qualifiedName in their Project Terms or Categories qualified name, changing the qualified name of the project will cause those qualified names to mismatch the Project name. Status is not updated using this call.

Parameters:

userId - unique identifier for requesting user, under which the request is performed

guid - guid of the project to update

suppliedProject - project to be updated

isReplace - flag to indicate that this update is a replace. When not set only the supplied (non null) fields are updated.

Returns:

a response which when successful contains the updated project when not successful the following Exception responses can occur

• UnrecognizedGUIDException the supplied guid was not recognised
• UserNotAuthorizedException the requesting user is not authorized to issue this request.
• FunctionNotSupportedException Function not supported

There are 2 types of deletion, a soft delete and a hard delete (also known as a purge). All repositories support hard deletes. Soft deletes support is optional. Soft delete is the default.

A soft delete means that the project instance will exist in a deleted state in the repository after the delete operation. This means that it is possible to undo the delete. A hard delete means that the project will not exist after the operation. when not successful the following Exceptions can occur

Parameters:

userId - unique identifier for requesting user, under which the request is performed

guid - guid of the project to be deleted.

isPurge - true indicates a hard delete, false is a soft delete.

Returns:

a void response when not successful the following Exception responses can occur

• UnrecognizedGUIDException the supplied guid was not recognised
• UserNotAuthorizedException the requesting user is not authorized to issue this request.
• FunctionNotSupportedException Function not supported
• InvalidParameterException one of the parameters is null or invalid.
• MetadataServerUncontactableException not able to communicate with a Metadata respository service. There is a problem retrieving properties from the metadata repository.
• EntityNotDeletedException a soft delete was issued but the project was not deleted.

restoreProject

public SubjectAreaOMASAPIResponse<Project> restoreProject(String userId,

userId - unique identifier for requesting user, under which the request is performed

guid - guid of the project to restore

Returns:

response which when successful contains the restored project when not successful the following Exception responses can occur

Get the terms in this project.

Parameters:

userId - unique identifier for requesting user, under which the request is performed

guid - guid of the Project

termHandler - Term handler

startingFrom - the starting element number for this set of results. This is used when retrieving elements beyond the first page of results. Zero means the results start from the first element.

pageSize - the maximum number of elements that can be returned on this request.

Returns:

a response which when successful contains the Project terms when not successful the following Exception responses can occur

• UnrecognizedGUIDException the supplied guid was not recognised
