setEntry

public void setEntry(ClonedServerEntry entry)

Description copied from interface: OperationContext

Sets the server entry associated with the target DN of this OperationContext.

Specified by:

setEntry in interface OperationContext

Parameters:

entry - the entry to set

getEntry

public ClonedServerEntry getEntry()

Description copied from interface: OperationContext

Gets the server entry associated with the target DN of this OperationContext. The entry associated with the DN may be altered during the course of processing an LDAP operation through the InterceptorChain. This place holder is put here to prevent the need for repetitive lookups of the target entry. Furthermore the returned entry may be altered by any Interceptor in the chain and this is why a ClonedServerEntry is returned instead of a ServerEntry. A ClonedServerEntry has an immutable reference to the original state of the target entry. The original state can be accessed via a call to ClonedServerEntry.getOriginalEntry(). The return value may be null in which case any lookup performed to access it may set it to prevent the need for subsequent lookups. Also note that during the course of handling some operations such as those that rename, move or rename and move the entry, may alter the DN of this entry. Interceptor implementors should not presume the DN or the values contained in this entry are currently what is present in the DIT. The original entry contained in the ClonedServerEntry shoudl be used as the definitive source of information about the state of the entry in the DIT before returning from the Partition subsystem.

Specified by:

getEntry in interface OperationContext

Returns:

the entry

throwReferral

public void throwReferral()

Set the throwReferral flag to true

Specified by:
