fun limit(limit: Int): DittoWriteTransactionPendingCursorOperation

Limit the number of documents that get returned when querying a collection for matching documents.

fun offset(offset: Int): DittoWriteTransactionPendingCursorOperation

Offset the resulting set of matching documents. This is useful if you aren't interested in the first N matching documents for one reason or another. For example, you might already have queried the collection and obtained the first 20 matching documents and so you might want to run the same query as you did previously but ignore the first 20 matching documents, and that is where you would use offset.

fun remove(): List<DittoDocumentId>

Remove all documents that match the query generated by the preceding function chaining.

fun sort(query: String, direction: DittoSortDirection): DittoWriteTransactionPendingCursorOperation

Sort the documents that match the query provided in the preceding find-like function call.
