equals

public boolean equals(java.lang.Object o)

Compare the given details to this one to see if they are equal. Equality is defined as pointing to the same light source, with the same transformation value.

Parameters:

o - The object to compare against

Returns:

true if these represent identical objects

hashCode

public int hashCode()

Calculate the hashcode for this object.

update

public void update(Light l,
                   float[] tx)

Update the details with a new set of values.

Parameters:

l - The light instance to be used

tx - The transform array to copy

getTransform

public float[] getTransform()

Return the current transform array. Don't play with the return value.

Returns:

The current transform matrix array

getLight

public Light getLight()

Get the current light instance in use.

Returns:

A reference to the current light
