Interface SerialPortOperationResult

All Superinterfaces:

OperationResult

public interface SerialPortOperationResult
extends OperationResult

The SerialPortOperationResult interface extends OperationResult to provide specific results for serial port operations.

It is used by the serial port device implementation to inform an application about the completion status of a requested operation.

The getResultCode() method, inherited from OperationResult, retrieves the result code of the operation. Standard result codes are defined in OperationResult.

This interface also provides additional functionalities specific to serial port operations, such as retrieving the data buffer and its length.
