Constructor Detail

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 Detail

set

public void set(Transform3D t1)

Set the SensorRead's transform to the value specified

Parameters:

t1 - this sensor's reading

get

public void get(Transform3D result)

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:

java.lang.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
