Detailed Description
This class represents a Phidget Weight Sensor. All methods to read weight data from the weight sensor are implemented in this class.
The Phidget Weight Sensor is simply an electronic scale with a USB interface. It provides one weight value, in kg.

Member Function Documentation
| final void com.phidgets.WeightSensorPhidget.addWeightChangeListener | ( | WeightChangeListener | l | ) | [inline] |
Adds a weight change listener. The weight change handler is a method that will be called when the weight has changed by at least the Trigger that has been set.
There is no limit on the number of weight change handlers that can be registered for a particular Phidget.
- Parameters:
-
l An implemetation of the WeightChangeListener interface

| native double com.phidgets.WeightSensorPhidget.getWeight | ( | ) | throws PhidgetException |
Returns the sensed weight in kg. This weight is in kg (kilograms), but can easily be converted into other units. The accuracy, sesitivity and range depends on the scale and version.
- Returns:
- The sensed weight
- Exceptions:
-
PhidgetException If this Phidget is not opened and attached. See open for information on determining if a device is attached.
| native double com.phidgets.WeightSensorPhidget.getWeightChangeTrigger | ( | ) | throws PhidgetException |
Returns the weight change trigger. This is the ammount by which the sensed weight must change between WeightChangeEvents. By default this is set to 5.
- Returns:
- The trigger value
- Exceptions:
-
PhidgetException If this Phidget is not opened and attached. See open for information on determining if a device is attached.
| final void com.phidgets.WeightSensorPhidget.removeWeightChangeListener | ( | WeightChangeListener | l | ) | [inline] |
Definition at line 74 of file WeightSensorPhidget.java.
| native void com.phidgets.WeightSensorPhidget.setWeightChangeTrigger | ( | double | newVal | ) | throws PhidgetException |
Sets the weight change trigger. This is the ammount by which the sensed weight must change between WeightChangeEvents. By default this is set to 5.
- Parameters:
-
newVal The new trigger value
- Exceptions:
-
PhidgetException If this Phidget is not opened and attached. See open for information on determining if a device is attached.
