Method Detail

connect

public void connect()
             throws com.smartgridready.driver.api.common.GenDriverException

Description copied from interface: GenDeviceApi

Connect the device.

Specified by:

connect in interface GenDeviceApi

Throws:

com.smartgridready.driver.api.common.GenDriverException - Generic error while reading from the device

disconnect

public void disconnect()
                throws com.smartgridready.driver.api.common.GenDriverException

Description copied from interface: GenDeviceApi

Disconnect the device.

Specified by:

disconnect in interface GenDeviceApi

com.smartgridready.driver.api.common.GenDriverException - Generic error while reading from the device

isConnected

public boolean isConnected()

Description copied from interface: GenDeviceApi

Checks if the device is connected.

Specified by:

isConnected in interface GenDeviceApi

Returns:

true if connected, false otherwise

authenticate

public void authenticate()
                  throws RestApiAuthenticationException,

                         RestApiServiceCallException,
                         RestApiResponseParseException

Description copied from interface: GenDeviceApi4Rest

Authenticates the REST API client. Authenticate uses the authentication method and credentials given within the external interface description XML of the device. The credentials may be given as parameters when loading the SGrRestApiDevice using the properties parameter of the DeviceDescriptionLoader.

Specified by:

authenticate in interface GenDeviceApi4Rest

Throws:

RestApiAuthenticationException - If the authentication failed.

java.io.IOException - If the communication with the server failed.

RestApiServiceCallException - If the service call could not be executed on the remote side.

RestApiResponseParseException - If parsing of the service response failed.
