  • Returns a hash representing the current version of the given queries. When a document matching such queries gets mutated, the hash will change as well.

    Please note that the hash depends on how queries are constructed, so you should make sure to always compare hashes generated with the same set of queries.

    Declaration

    Swift

    public func queriesHash(queries: [DittoLiveQuery]) -> UInt

    Parameters

    queries

    A list of DittoLiveQuery objects that you want to get the hash for.

    Return Value

    A hash representing the current version of the given queries.

  • Returns a sequence of English words representing the current version of the given queries. When a document matching such queries gets mutated, the words will change as well.

    Please note that the resulting sequence of words depends on how queries are constructed, so you should make sure to always compare hashes generated with the same set of queries.

    Declaration

    Swift

    public func queriesHashMnemonic(queries: [DittoLiveQuery]) -> String

    Parameters

    queries

    A list of DittoLiveQuery objects that you want to get the mnemonic hash for.

    @discardableResult
    public func write(
        _ block: @escaping (DittoWriteTransaction) -> Void
    ) -> [DittoWriteTransactionResult]
