In NSEntityMigrationPolicy Class Reference, I read: beginEntityMapping:manager:error: Invoked by the migration manager at the start of a given entity mapping.
endEntityMapping:manager:error: Invoked by the migration manager at the end of a given entity mapping. Simple enough. However, I find that in mysubclass, beginEntityMapping:manager:error: is sent to a certain instance, then createDestinationInstancesForSourceInstance:::: is sent to the same instance, once for each object in the store. So far, so good. But then endEntityMapping:manager:error: is sent to a *different instance*! Makes it difficult to log a summary based on instance variables. What could be the logic of this? Jerry Krinock Following is an abridged console log when I log the method name, 'self', the 'mapping' parameter and the 'manager' parameter in each of the three methods. The middle method is invoked once for each of three objects in the store, so there are 5 lines. Note that 'mapping' and 'manager' are always the same but 'self' is different in the last line. -beginEntityMapping::: self:0x176d3070 mapping:0x176d2ef0 manager:0x1eb02680 -createDestinationInstancesForSourceInstance:::: self:0x176d3070 mapping:0x176d2ef0 manager:0x1eb02680 -createDestinationInstancesForSourceInstance:::: self:0x176d3070 mapping:0x176d2ef0 manager:0x1eb02680 -createDestinationInstancesForSourceInstance:::: self:0x176d3070 mapping:0x176d2ef0 manager:0x1eb02680 -endEntityMapping::: self:0x1eb67880 mapping:0x176d2ef0 manager:0x1eb02680 _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
