Method Detail

isCloser

public int isCloser(Object x,

    -1 is returned if the value of x is considered closer to this object than the value of y.
    +1 is returned if the value of y is considered closer to this object than the value of x.
     0 is returned if the values of x and y are equally close to this object.
