Method Detail

keys

public java.util.Enumeration<java.lang.Object> keys()

Overriden to be able to write properties sorted by keys to the disk

Overrides:

keys in class java.util.Hashtable<java.lang.Object,java.lang.Object>

See Also:

Hashtable.keys()

sortKeys

public static java.util.Enumeration<?> sortKeys(java.util.Set<java.lang.String> keySet)

To be compatible with version control systems, we need to sort properties before storing them to disk. Otherwise each change may lead to problems by diff against previous version - because Property entries are randomly distributed (it's a map).

Parameters:

keySet - non null set instance to sort

Returns:

non null list wich contains all given keys, sorted lexicographically. The list may be empty if given set was empty
