public function BeginTransaction(
    name : String, 
    isSerializing : boolean, 
    context : TransactionContext
) : Transaction

Parameters

  • isSerializing
    Type: System.Boolean
    Determines the value of transaction.IsSerializing. true indicates that the model is being read from file.

Return Value

Type: Microsoft.VisualStudio.Modeling.Transaction
A Transaction object.

Remarks

Use this version if you have written rules and event handlers that use information passed in a transaction context object. Because rules are called in an arbitrary order at the end of a transaction, it is not possible to pass information to or between them directly. The transaction context is a dictionary in which any kind of information can be passed.

Examples

// In a rule:
UsefulInfo info = this.Store.TransactionManager.CurrentTransaction
    .TopLevelTransaction.Context.ContextInfo["akey"] as UsefulInfo;
