clone

public java.lang.Object clone(java.lang.Object object)

Clone and store the Hibernate POJO(s)

clone

public java.lang.Object clone(java.lang.Object object,
                              boolean assignable)

Clone and store the Hibernate POJO

Parameters:

object - the object to store

assignable - if the assignation from source to target class (via ClassMapper) must be checked

Returns:

the clone

merge

public java.lang.Object merge(java.lang.Object object)

Merge the clone POJO to its Hibernate counterpart

merge

public java.lang.Object merge(java.lang.Object object,
                              boolean assignable)

Merge the clone POJO to its Hibernate counterpart

clonePojo

                                     boolean assignable)

Clone and store the Hibernate POJO

Parameters:

pojo - the pojo to store

assignable - does the source and target class must be assignable?

Throws:

NotAssignableException - if source and target class are not assignable

cloneMap

protected java.util.Map<?,?> cloneMap(java.util.Map<?,?> hibernatePojoMap,
                                      boolean assignable)

Clone and store a map of Hibernate POJO
