Method Detail

compareTo

public static int compareTo(com.mhhe.clrs2e.DynamicSetElement e,
                            java.lang.Object o)

Compares a DynamicSetElement to another object. If the other object is also a DynamicSetElement, the keys of both are compared. If the other object is not a DynamicSetElement object but does implement Comparable, then the key of of the DynamicSetElement is compared to the other object. Otherwise, the other object does not implement Comparable, and a ClassCastException is thrown.

Parameters:

e - The DynamicSetElement.

o - The other object.

Returns:

A negative integer if e is less; 0 if the objects are equal; a positive integer if e is greater.

Throws:

java.lang.ClassCastException - if o does not implement Comparable.

cast

public static com.mhhe.clrs2e.DynamicSetElement cast(java.lang.Object o)

Casts an object to DynamicSetElement, throwing a ClassCastException if the object fails to implement the DynamicSetElement interface.

Parameters:

o - The object.

Returns:

The object o, but cast as a DynamicSetElement.

Throws:

java.lang.ClassCastException - if o does not implement the DynamicSetElement interface.
