validateID

public static void validateID(int oldID,
 int newID)
                       throws IllegalArgumentException,

Parameters:

oldID - the old database ID

newID - the new database ID

Throws:

IllegalArgumentException - if the database ID is negative or zero

IllegalStateException - if we are attempting to change the database ID

 int newID,
 boolean allowZero)
                       throws IllegalArgumentException,

Validates a database ID. Used to enforce database ID behavior - that the ID cannot be zero or negative, and it cannot be updated once set.

Parameters:

oldID - the old database ID

newID - the new database ID

allowZero - TRUE to allow setting the ID to zero, otherwise FALSE

Throws:

IllegalArgumentException - if the database ID is negative (or zero if allowZero is FALSE)

IllegalStateException - if we are attempting to change the database ID

compareTo

public int compareTo(Object o)

Specified by:

compareTo in interface Comparable<Object>

cacheKey
