Details |
MDG_PreMerge is called after a merge process has been initiated by the user and before Enterprise Architect performs the merge process. This event is called after a user has performed their interactions with the merge screen and has confirmed the merge with the OK button, but before Enterprise Architect performs the merge process using the data provided by the MDG_Merge call, before any changes have been made to the model or the connected project. This event is made available to provide the Add-In with the opportunity to generally set internal Add-In flags to augment the MDG_PreGenerate, MDG_PostGenerate and MDG_PreReverse events. File save checking should not be performed with this function, but should be handled by MDG_PreGenerate, MDG_PostGenerate and MDG_PreReverse.
