Method Detail

getDraftWorkflow

public JiraWorkflow getDraftWorkflow(JiraServiceContext jiraServiceContext,
                                     String parentWorkflowName)

Description copied from interface: WorkflowService

Given a parentWorkflowName, this methods will retrieved the relevant draft workflow linked to that parent.
If the parentWorkflow doesn't exist, this method returns null and will log an error in the servicecontext errorcollection. If no DraftWorkflow exists, then this method will simply return null.

Specified by:

getDraftWorkflow in interface WorkflowService

Parameters:

jiraServiceContext - service context with user and error collection

parentWorkflowName - The parent workflow name to create an draft copy of.

Returns:

A draft workflow or null if no draft workflow is found

createDraftWorkflow

public JiraWorkflow createDraftWorkflow(JiraServiceContext jiraServiceContext,
                                        String parentWorkflowName)

Description copied from interface: WorkflowService

Creates a copy of an active workflow for editing. This will not overwrite the current active workflow

Specified by:

createDraftWorkflow in interface WorkflowService

Parameters:

jiraServiceContext - service context with user and error collection

parentWorkflowName - The parent workflow name to create an draft copy of.

Returns:

A copy of the active workflow

deleteDraftWorkflow

public boolean deleteDraftWorkflow(JiraServiceContext jiraServiceContext,
                                   String parentWorkflowName)

Description copied from interface: WorkflowService

Deletes draft workflows (there should only be one) that are associated with the given parent workflow name.

Specified by:

deleteDraftWorkflow in interface WorkflowService

Parameters:

jiraServiceContext - service context with user and error collection

parentWorkflowName - The parent workflow name that the draft workflow to be deleted is associated with

Returns:

true if an draft workflow was deleted, false otherwise

overwriteActiveWorkflow

public void overwriteActiveWorkflow(JiraServiceContext jiraServiceContext,
                                    String parentWorkflowName)

Description copied from interface: WorkflowService

This method will overwrite the parentWorkflow with a draft Workflow if it exists. If it doesn't exist, this method will add an error to the errorcollection in the service context. The method will also check for the existance of the parent, and call WorkflowService.validateOverwriteWorkflow(com.atlassian.jira.bc.JiraServiceContext, String) to ensure the active workflow isn't being overwritten with an invalid draft workflow.

Specified by:

overwriteActiveWorkflow in interface WorkflowService

Parameters:

jiraServiceContext - service context with user and error collection

parentWorkflowName - The parent workflow name that will be overwritten with its draft workflow

validateOverwriteWorkflow

public void validateOverwriteWorkflow(JiraServiceContext jiraServiceContext,
                                      String workflowName)

Description copied from interface: WorkflowService

Validates that the draft workflow with the given name is allowed to be saved into the corresponding active workflow. Basically you are allowed to add new Steps and change the transitions, but you are not allowed to remove any steps/statuses, or change an existing association between a step ID and an Issue status.

Specified by:

validateOverwriteWorkflow in interface WorkflowService

Parameters:

jiraServiceContext - JiraServiceContext

workflowName - Name of the workflow to be validated.

updateWorkflow

public void updateWorkflow(JiraServiceContext jiraServiceContext,
                           JiraWorkflow workflow)

Description copied from interface: WorkflowService

Updates the workflow descriptor provided in the persistance mechanism implemented. This method can be used for draft workflows, as well as for copies of active workflows. This method does not save the changes to the active workflow. Instead, this is meant to be used to make persistent changes to your working edit. Once all changes have been made you can over write the active workflow by calling WorkflowService.overwriteActiveWorkflow(com.atlassian.jira.bc.JiraServiceContext, String) }

Specified by:

updateWorkflow in interface WorkflowService

Parameters:

jiraServiceContext - service context with user and error collection

workflow - contains the descriptor that the workflow will be updated to.
