SensorRead
public SensorRead()Constructs a SensorRead object with default parameters. The default values are as follows:-
number of buttons : 0
button values : 0 (for all array elements)
transform : identity
time : current time
-
SensorRead
public SensorRead(int numButtons) Constructs a SensorRead object with the specified number of buttons.- Parameters:
numButtons
- the number of buttons for this SensorRead
-
-
Method Details
-
set
Set the SensorRead's transform to the value specified- Parameters:
t1
- this sensor's reading
-
get
Retrieve the SensorRead's transform and place it in result- Parameters:
result
- the recipient of the this sensor's reading
-
setTime
public void setTime(long time) Sets this SensorRead's time stamp to the specified argument- Parameters:
time
- the time to associate with this reading
-
getTime
public long getTime()Retrieve this SensorRead's associated time stamp- Returns:
- the SensorRead's time as a long
-
setButtons
public void setButtons(int[] values) Sets the values of all buttons for this SensorRead object.- Parameters:
values
- array contining the new buttons for this SensorRead- Throws:
ArrayIndexOutOfBoundsException
- if this object has 0 buttons or if values.length is less than the number of buttons in this object.
-
getButtons
public void getButtons(int[] values) Copies the array of button values for this SensorRead object into the specified array. This method has no effect if this SensorRead object has 0 buttons. The array must be large enough to hold all of the buttons.- Parameters:
values
- array that will receive the values of all buttons for this SensorRead
-
getNumButtons
public int getNumButtons()Returns the number of buttons associated with this SensorRead object.- Returns:
- the number of buttons associated with this SensorRead object
