Method Detail

copyDictionary

public static <K> java.util.Dictionary<K,java.lang.Object> copyDictionary(java.util.Dictionary<K,java.lang.Object> in)

Copy a dictionary. Deep copy where values aren't immutable. I.e. Vector and arrays.

Parameters:

in - The Dictionary to create a copy of.

Returns:

A copy of the Dictionary.

dictionariesAreEqual

public static <K> boolean dictionariesAreEqual(java.util.Dictionary<K,java.lang.Object> first,
                                               java.util.Dictionary<K,java.lang.Object> second)

Recursive comparison of two dictionaries for equality. Equality is defined as (o1 == null && 02 == null) || o1.equals(o2).

Parameters:

first - The first Dictionary to compare.

second - The second Dictionary to compare.

Returns:

true if both dictionaries are either null or recursively equal.

dictionariesAreNotEqual

public static <K> boolean dictionariesAreNotEqual(java.util.Dictionary<K,java.lang.Object> first,
                                                  java.util.Dictionary<K,java.lang.Object> second)
