public class MOMutableColumn<V extends org.snmp4j.smi.Variable>
extends MOColumn<V>

The MOMutableColumn class represents mutable columnar SMI objects. It represents all instances of a table's column not only a single instance (cell).

Objects represented by MOMutableColumn can be modified via SNMP, thus MOColumn supports read-only, read-write, and read-create maximum access.

public boolean isMutableInService()

isMandatory

public boolean isMandatory()

Returns true if this column must be specified in a SET request which creates a row.

Returns:

true if this row has a maximum access of READ-CREATE and has a null default value, false otherwise.

setMandatory

public void setMandatory(boolean mandatory)

Sets a flag that determines if this column must be specified in a SET request which creates a row. The default is true.

Parameters:

mandatory - if true and a row has a maximum access of READ-CREATE and has a null default value, then it must be provided in order to activate the row.
