What is the globals object good for?
Hi all
What is the globals object good for we are seeing in all the business rules?
With the globals variable, you can store data or objects globally and transfer it from one process steps to another.
- For the runtime of a consolidation
With the globals you can populate a variable or create an object in the first entity you calculate and store it for all other entities of a consolidation so that you don't need to calculate it again. - For a cubeview/report
With the globals you can populate a variable or create an object in a dynamic calc when calculating the first cell and store it for all other cells of the cubeview so that you don't need to calculate it again.
This is a sample how to count process steps
Dim aSimpleCounter As Integer 'lock the process to avoid overrides SyncLock Globals.LockObjectForInitialization 'Initialize aSimpleCounter with the stored variable, or initialize it with 0 simpleCounter = globals.GetInt32Value("SimpleCounter", 0) 'Count it up by 1 simpleCounter +=1 'Save it to globals globals.SetInt32Value("SimpleCounter", simpleCounter) End SyncLock
You can also store objects like list or dictionaries in globals
Dim nameToStore As String = "MyObjectName" 'Definition of a list Dim anyObject As list(of string) 'lock the process to avoid multiple initialisations SyncLock Globals.LockObjectForInitialization 'Check if the object is already stored in globals anyObject = globals.GetObject(nameToStore) 'If not initialize it If anyObject Is Nothing Then 'create and populate the list anyObject = New list(of string) anyObject.add("One") anyObject.add("Stream") anyObject.add("Software") globals.SetObject(nameToStore , anyObject) End If End SyncLock 'Continue working
Be careful, many object like list and dictionaries are not supporting mutithreaded (support working in parallel), so you can not use them to add members to the list during a report or a consolidation.
But there are multithreaded versions you can use for this purpose
'Additional Imports for concurent list and dictionary Imports System.Collections.Concurrent 'create a concurrent dictionary Dim concDict As New ConcurrentDictionary()
