Constructor Details

FetchChangelogUpdatesControl

public FetchChangelogUpdatesControl(boolean isCritical,
 ReplicaId replicaId,
 Set<FetchChangelogUpdatesControl.FetchChangelogUpdatesInfo> info)

Creates a new instance of ReplicationRequestControl.

Parameters:

isCritical - Specifies whether the control is critical.

replicaId - The replica id.

info - The ReplicationRequestInfo object containing the necessary information for replication request.

Method Details

getOid

public String getOid()

Description copied from interface: Control

Returns the numeric OID associated with this control.

Specified by:

getOid in interface Control

Returns:

the numeric OID associated with this control

getReplicaStateOrEmpty

public ReplicaState getReplicaStateOrEmpty(Dn domain)

Returns the replica state of the replication request control.

Parameters:

domain - the domain for which to return the replica state.

Returns:

the replica state of the replication request control

getPurgePointOrOldestCsn

public CSN getPurgePointOrOldestCsn(Dn domain)

Returns the purge point of the replication request control.

Parameters:

domain - the domain for which to return the purge point.

Returns:

the purge point of the replication request control

getScpOrOldestCsn

public CSN getScpOrOldestCsn(Dn domain)

Returns the stable consistency point of the replication request control.

Parameters:

domain - the domain for which to return the stable consistency point.

Returns:

the stable consistency point of the replication request control

isCritical

public boolean isCritical()

Description copied from interface: Control

Returns true if it is unacceptable to perform the operation without applying the semantics of this control.

The criticality field only has meaning in controls attached to request messages (except UnbindRequest). For controls attached to response messages and the UnbindRequest, the criticality field SHOULD be false, and MUST be ignored by the receiving protocol peer. A value of true indicates that it is unacceptable to perform the operation without applying the semantics of the control.

Specified by:

isCritical in interface Control

Returns:

true if this control must be processed by the Directory Server, or false if it can be ignored.

getAlias

public String getAlias()

Description copied from interface: Control

Returns the control "friendly name" alias for the control.

Specified by:

getAlias in interface Control

Returns:

"Friendly name" alias for the control.

hasValue

public boolean hasValue()

Description copied from interface: Control

Returns true if this control has a value. In some circumstances it may be useful to determine if a control has a value, without actually calculating the value and incurring any performance costs.

Specified by:

hasValue in interface Control

Returns:

true if this control has a value, or false if there is no value.

getValue

public ByteString getValue()

Description copied from interface: Control

Returns the value, if any, associated with this control. Its format is defined by the specification of this control.

Specified by:

getValue in interface Control

Returns:

The value associated with this control, or null if there is no value.

toString

public String toString()

Overrides:

toString in class Object
