ResultSet

public class ResultSet

Represents a query result set. The rows are accessable either in a blocking fashion using a RowSequence or in a non-blocking fashion using nextRow() function.

  • Instantiate an instance of ResultSet.

    Declaration

    Swift

    public init(_ resultFetcher: ResultFetcher, connection: Connection)

    Parameters

    resultFetcher

    An implementation of ResultFetcher protocol to fetch the query results.

  • Fetch the next row of the query result. This function is non-blocking.

    Declaration

    Swift

    public func nextRow(callback: @escaping (([Any?]?, Error?)) -> ())

    Parameters

    callback

    A callback to call when the next row of the query result is ready.

  • Fetch the column titles of the query result. This function is non-blocking

    Declaration

    Swift

    public func getColumnTitles(callback: @escaping (([String]?, Error?)) -> ())

  • Called to indicate no further operations will be called on the result set. A ResultSet will keep a connection alive until this method is called. When called this method enables the underlying connection to be released and in the case where a connection pool is used, returned to the pool for reuse.

    Declaration

    Swift

    public func done()

  • Type alias for closures to be passed to the forEach method

    Declaration

    Swift

    public typealias RowOperation = ([Any?]?, Error?) -> Void

  • Type alias for closures to be passed to the forEach method which allows asynchronous opertions.

    Declaration

    Swift

    public typealias RowOperationWithNext = ([Any?]?, Error?, () -> Void) -> Void

  • Execute the supplied RowOperation against each row returned from the database

    Declaration

    Swift

    public func forEach(operation: @escaping RowOperation)

    Parameters

    operation

    A callback to be executed against each row in the result set.

  • Execute the supplied RowOperation against each row returned from the database

    Declaration

    Swift

    public func forEach(operation: @escaping RowOperationWithNext)

    Parameters

    operation

    A callback to be executed against each row in the result set.
