Return the Object at the given index.

Parameters:

i - the index of the Object

Returns:

return the requested Object.

getIndex

public int getIndex(java.lang.Object o)

Return the index for a given Object, indicating its order in the range.

Parameters:

o - the Object to lookup.

Returns:

the index of the Object in the range model, -1 if the Object is not found in the model.
