expect fun delete()

Deletes a database. Deleting a database will stop all replicators, live queries and all listeners attached to it. Although attempting to close a closed database is not an error, attempting to delete a closed database is.

expect fun delete(document: Document)

Deletes a document from the default collection. When write operations are executed concurrently, the last writer will overwrite all other written values. Calling this function is the same as calling delete(Document, ConcurrencyControl.LAST_WRITE_WINS)

expect fun delete(document: Document, concurrencyControl: ConcurrencyControl): Boolean

Deletes a document from the default collection. When used with lastWriteWins concurrency control, the last write operation will win if there is a conflict. When used with FAIL_ON_CONFLICT concurrency control, delete will fail and the method will return false.

Delete a collection by name in the specified scope. If the collection doesn't exist, the operation will be no-ops. Note: the default collection cannot be deleted.

expect fun getScope(name: String): Scope?

Get a scope object by name. As the scope cannot exist by itself without having a collection, the null value will be returned if there are no collections under the given scope’s name. Note: The default scope is exceptional, and it will always be returned.
