Class GenericDeviceConfig

java.lang.Object

jdk.dio.generic.GenericDeviceConfig

All Implemented Interfaces:

DeviceConfig<GenericDevice>, DeviceConfig.HardwareAddressing

public final class GenericDeviceConfig
extends java.lang.Object
implements DeviceConfig<GenericDevice>, DeviceConfig.HardwareAddressing

The GenericDeviceConfig class encapsulates the hardware addressing information of generic device.

Note that it does not encapsulates static or dynamic configuration parameters; and that configuration parameters should be set using the GenericDevice.setControl method.

An instance of GenericDeviceConfig can be passed to the DeviceManager.open(DeviceConfig) or DeviceManager.open(Class, DeviceConfig) method to open the designated generic device with the specified configuration. A InvalidDeviceConfigException is thrown when attempting to open a device with an invalid or unsupported configuration.

Constructor Detail

GenericDeviceConfig

public GenericDeviceConfig(int controllerNumber,
                   int channelNumber)

Creates a new GenericDeviceConfig with the specified hardware addressing information .

Parameters:

controllerNumber - the hardware controller's number (a positive or zero integer) or DeviceConfig.DEFAULT.

channelNumber - the hardware device's number (a positive or zero integer) or DeviceConfig.DEFAULT.

Throws:

java.lang.IllegalArgumentException - if any of the following is true:

• controllerNumber is not in the defined range;
• channelNumber is not in the defined range.

GenericDeviceConfig

public GenericDeviceConfig(java.lang.String controllerName)

Creates a new GenericDeviceConfig with the specified hardware addressing information.

Parameters:

controllerName - the controller name (such as its device file name on UNIX systems).

Throws:

java.lang.NullPointerException - if controllerName is null.

Method Detail

getChannelNumber

public int getChannelNumber()

Gets the configured channel number.

Returns:

the hardware device channel's number (a positive or zero integer) or DeviceConfig.DEFAULT .

getControllerNumber

public int getControllerNumber()

Gets the configured controller number.

Specified by:

getControllerNumber in interface DeviceConfig.HardwareAddressing

Returns:

the hardware device controller's number (a positive or zero integer) or DeviceConfig.DEFAULT.

getControllerName

public java.lang.String getControllerName()

Gets the configured controller name (such as its device file name on UNIX systems).

Specified by:

getControllerName in interface DeviceConfig.HardwareAddressing

Returns:

the controller name or null.

hashCode

public int hashCode()

Returns the hash code value for this object.

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code value for this object.

equals

public boolean equals(java.lang.Object obj)

Checks two GenericDeviceConfig objects for equality.

Overrides:

equals in class java.lang.Object

Parameters:

obj - the object to test for equality with this object.

Returns:

true if obj is a GenericDeviceConfig and has the same hardware addressing information and configuration parameter values as this GenericDeviceConfig object.
