Summary

Rename the Workspace.

Properties

Name	Direction	Type	Default	Description
InputWorkspace	Input	Workspace	Mandatory
OutputWorkspace	Output	Workspace	Mandatory
RenameMonitors	Input	boolean	False	If true, and monitor workspace found attached to the source workspace, the monitors workspace is renamed too. The monitor workspace name is created from the new workspace name: NewWSName by adding the _monitors suffix (e.g.: NewWSName_monitors)
OverwriteExisting	Input	boolean	True	If true any existing workspaces with the output name will be overwritten. Defaults to true to maintain backwards compatibility.

Description

Renames a workspace to a different name in the data service. If the same name is provided for input and output then the algorithm will fail with an error. The Renaming is implemented as a removal of the original workspace from the data service and re-addition under the new name.

If run on a group workspace, the members of the group will be renamed if their names follow the pattern groupName_1, groupName_2, etc. (they will be renamed to newName_1, newname_2, etc.). Otherwise, only the group itself will be renamed - the members will keep their previous names.

The new name can be the same as any existing workspaces if the overwrite flag is set to true. This will replace the existing workspace. If the Overwrite flag is set to false and any name is in use RenameWorkspace will not rename the workspace and log an error.

Warning

RenameWorkspace is set to overwrite by default to maintain backwards compatibility. Ensure the overwrite flag is set to false to prevent any existing workspaces being replaced with the renamed workspace.

Usage

Example

AnalysisDataService.clear()
myWs=CreateSampleWorkspace()
mon_ws = CreateSampleWorkspace()
myWs.setMonitorWorkspace(mon_ws)
print("*********************************************************************")
print("{0:20}|{1:>20}|{2:>20}|".format("Existing WS names: ",myWs.name(),mon_ws.name()))
obj_inADS = AnalysisDataService.getObjectNames()
obj_inADS.sort()
print("{0:20}|{1:>6}| With Names: |{2:>20}|{3:>20}|".format("Exist in ADS: ",len(obj_inADS),obj_inADS[0],obj_inADS[1]))

NameA = RenameWorkspace(myWs)

print("***** After simple rename:")
print("{0:20}|{1:>20}|{2:>20}|".format("Existing WS names: ",NameA.name(),mon_ws.name()))
obj_inADS = AnalysisDataService.getObjectNames()
obj_inADS.sort()
print("{0:20}|{1:>6}| With Names: |{2:>20}|{3:>20}|".format("Exist in ADS: ",len(obj_inADS),obj_inADS[0],obj_inADS[1]))

print("Old pointer to myWs refers to workspace with new name:  {}".format(myWs.name()))
print("*********************************************************************")
print("***** After renaming workspace and monitors workspace together:")

NameB = RenameWorkspace(myWs,RenameMonitors=True)

print("{0:20}|{1:>20}|{2:>20}|".format("Existing WS names: ",NameB.name(),mon_ws.name()))
obj_inADS = AnalysisDataService.getObjectNames()
obj_inADS.sort()
print("{0:20}|{1:>6}| With Names: |{2:>20}|{3:>20}|".format("Exist in ADS: ",len(obj_inADS),obj_inADS[0],obj_inADS[1]))

mon_ws1 = NameB.getMonitorWorkspace()
print("The name of the monitor workspace attached to workspace:{0:>6}| Is:  {1:>10}|".
         format(NameB.name(),mon_ws1.name()))
print("*********************************************************************")

Output:

*********************************************************************
Existing WS names:  |                myWs|              mon_ws|
Exist in ADS:       |     2| With Names: |              mon_ws|                myWs|
***** After simple rename:
Existing WS names:  |               NameA|              mon_ws|
Exist in ADS:       |     2| With Names: |               NameA|              mon_ws|
Old pointer to myWs refers to workspace with new name:  NameA
*********************************************************************
***** After renaming workspace and monitors workspace together:
Existing WS names:  |               NameB|      NameB_monitors|
Exist in ADS:       |     2| With Names: |               NameB|      NameB_monitors|
The name of the monitor workspace attached to workspace: NameB| Is:  NameB_monitors|
*********************************************************************

Example - Setting Overwrite on and off:

#Clear the ADS before starting
AnalysisDataService.clear()

#Create an existing workspace called 'wsOld'
CreateWorkspace([0], [0], OutputWorkspace="wsOld")

#Next create a workspace we are going to rename
CreateWorkspace([0], [0], OutputWorkspace="wsNew")

#This will fail telling us that 'wsOld' already exists
print('Trying to rename with OverwriteExisting set to false.')
try:
    RenameWorkspace(InputWorkspace="wsNew", OutputWorkspace="wsOld", OverwriteExisting=False)
except RuntimeError:
    print('RuntimeError: The workspace wsOld already exists')

#This will succeed in renaming and 'wsOld' will be replaced with 'wsNew'
print('Trying to rename with OverwriteExisting set to true.')
RenameWorkspace(InputWorkspace="wsNew", OutputWorkspace="wsOld", OverwriteExisting=True)
print('Succeeded')

Output:

Trying to rename with OverwriteExisting set to false.
RuntimeError: The workspace wsOld already exists
Trying to rename with OverwriteExisting set to true.
Succeeded
