Method Summary
`abstract GrouperAPI`	`clone()` deep clone the fields in this object
`Object`	`dbVersion()` version of this object in the database
`void`	`dbVersionClear()` set to null (e.g.
`Set<String>`	`dbVersionDifferentFields()` see which fields have changed compared to the DB state (last known) note that attributes will print out: attribute__attributeName

Method Detail

fieldValue

public Object fieldValue(String fieldName)

call this method to get the field value (e.g. from dbVersionDifferentFields). some objects have different interpretations (e.g. Group will process attribute__whatever)

Specified by:: fieldValue in interface GrouperUtil.FieldValuable

Parameters:: fieldName -
Returns:: the value

dbVersion

public Object dbVersion()

version of this object in the database

Returns:: the db version

dbVersionIsDifferent

public boolean dbVersionIsDifferent()

see if the state of this object has changed compared to the DB state (last known)

Returns:: true if changed, false if not

dbVersionDifferentFields

public Set<String> dbVersionDifferentFields()

see which fields have changed compared to the DB state (last known) note that attributes will print out: attribute__attributeName

Returns:: a set of attributes changed, or empty set if none

dbVersionReset

public void dbVersionReset()

take a snapshot of the data since this is what is in the db

dbVersionClear

public void dbVersionClear()

set to null (e.g. on delete)

onDelete

public boolean onDelete(org.hibernate.Session s)
                 throws org.hibernate.CallbackException

Specified by:: onDelete in interface org.hibernate.classic.Lifecycle

Throws:: org.hibernate.CallbackException
See Also:: Lifecycle.onDelete(org.hibernate.Session)
