Method Detail

getValue

void getValue(float[] col)

Write the value of the colour to the given array.

Parameters:

col - The array of colour values to be filled in where
value[0] = Red component [0-1]
value[1] = Green component [0-1]
value[2] = Blue component [0-1]
value[3] = Alpha component [0-1]

Throws:

java.lang.ArrayIndexOutOfBoundsException - The provided array was too small

setValue

void setValue(float[] value)

Set the colour value in the given eventIn. Colour values are required to be in the range [0-1].

The value array must contain at least three elements. If the array contains more than 4 values only the first three values will be used and the rest ignored.

If the array of values does not contain at least 3 elements an ArrayIndexOutOfBoundsException will be generated. If the colour values are out of range an IllegalArgumentException will be generated.

Parameters:

value - The array of colour values where
value[0] = Red component [0-1]
value[1] = Green component [0-1]
value[2] = Blue component [0-1]
value[3] = Alpha component [0-1]

Throws:

java.lang.IllegalArgumentException - A colour value(s) was out of range

java.lang.ArrayIndexOutOfBoundsException - A value did not contain at least three values for the colour component
