Method Detail

toString

public java.lang.String toString()

toString.

Overrides:

toString in class java.lang.Object

equals

public boolean equals(java.lang.Object ob)

equals.

Overrides:

equals in class java.lang.Object

Parameters:

ob - an Object.

Returns:

true if this is equal to o, else false.

compareTo

public int compareTo(SigPair<C> p)
