There is not need to instantiate this class in your code. A client will emit an error state via QOpcUaClient::connectError in case an error has happened while establishing a connection.
The error can be caused by the backend itself or by the server rejecting the connection. If case of errors issued by the local backend, they can be ignored by calling the function setIgnoreError ().
Specifies at which step during the connection establishment the error occurred.

Default constructs an error state with no parameters set.
Constructs an error state from other .
Returns the connection step in which the error occurred.
另请参阅 setConnectionStep ().
Returns the OPC UA status code of the error occurred.
另请参阅 setErrorCode ().
Returns if this client side error should be ignored.
另请参阅 setIgnoreError ().
Returns if the occurred error is a client side error.
Sets if the occurred error is a client side error to clientSideError .
另请参阅 isClientSideError ().
Sets the connection step in which the error occurred to step .
另请参阅 connectionStep ().
Sets the OPC UA status code of the error occurred to error .
另请参阅 errorCode ().
Sets if this client side error should be ignored to ignore .
Setting this flag does only work if the error is actually a client side error.
另请参阅 ignoreError ().
Sets the values of rhs in this error state.
