DITWriteStrategy
enum DITWriteStrategy : NSUInteger {}
Defines the various strategies available when inserting a document into a collection.
-
The existing document will be merged with the document being inserted, if there is a pre-existing document.
Declaration
Objective-C
DITWriteStrategyMerge = 1
-
An existing document will be overwritten. This can be thought of as first removing the existing document completely and then inserting the new document in its place, if there is a pre-existing document.
Declaration
Objective-C
DITWriteStrategyOverwrite = 2
-
Insert the document only if there is not already a document with the same ID in the store. If there is already a document in the store with the same ID then this will be a no-op.
Declaration
Objective-C
DITWriteStrategyInsertIfAbsent = 3
-
Insert the document, with its contents treated as default data, only if there is not already a document with the same ID in the store. If there is already a document in the store with the same ID then this will be a no-op. Use this strategy if you want to insert default data for a given document ID, which you want to treat as common initial data amongst all peers and that you expect to be mutated or overwritten in due course.
Declaration
Objective-C
DITWriteStrategyInsertDefaultIfAbsent = 4
