getPrimaryKey

protected Object getPrimaryKey(T object)

Return the domain object's primary key - typically an Integer. Pretty much all RHQ domain objects use 'id' as the field name for the primary key, so provide a default implementation that grabs the 'id' field to make things as easy as possible for subclasses.

Parameters:

object - a domain object

Returns:

U the domain object's primary key - typically an Integer
