                                        java.io.Serializable id)

Return a clone of the persistent instance with the given identifier, assuming that the instance exists.

Parameters:

theClass - class of the persistent object

id - a valid identifier of an existing persistent instance of the class

Returns:

the cloned object

findByProperty

protected java.util.List findByProperty(java.lang.Class c,
                                        java.lang.String propertyName,
                                        java.lang.Object value,
                                        int firstElement,
                                        int maxElements)

Find objects by property value

Parameters:

c - class of the hibernated object

propertyName - name of the property

value - value to find

firstElement - the first result, numbered from 0

maxElements - the maximum number of results

Returns:

findByPropertyContent

protected java.util.List findByPropertyContent(java.lang.Class c,
                                               java.lang.String propertyName,
                                               java.lang.String value,
                                               int firstElement,
                                               int maxElements)

Find objects by property value where the property contains the value

Parameters:

c - class of the hibernated object

propertyName - name of the property

value - value to find

firstElement - the first result, numbered from 0

maxElements - the maximum number of results

Returns:

filter

protected java.util.Collection filter(java.util.Collection collection,
                                      java.lang.String filter)

Apply a filter to a persistent collection. A filter is a Hibernate query that may refer to this, the collection element. Filters allow efficient access to very large lazy collections. (Executing the filter does not initialize the collection.)

Parameters:

collection - a persistent collection to filter

filter - a filter query string

Returns:

Collection the resulting collection
