getStorageType
public static org.snmp4j.smi.Integer32 getStorageType(MOTableRow row, MOTable<?,?,?> table)
Gets the value of the StorageType column (if it exists) in the specified row and table. It starts searching for theStorageType
column from the last column and then proceeds down to the first until it finds it. If noStorageType
column can be found,null
is returned.- Parameters:
row
- a row with aStorageType
column (otherwisenull
is returned).table
- the table of the givenrow
.- Returns:
- the
Integer32
value of theStorageType
column in the givenrow
ornull
if the table has noStorageType
column or the value of that column isnull
. - Since:
- 3.3.1
-
validate
public int validate(org.snmp4j.smi.Integer32 newValue, org.snmp4j.smi.Integer32 oldValue)
- Overrides:
validate
in classMOMutableColumn<org.snmp4j.smi.Integer32>
-
prepareRow
public void prepareRow(SubRequest<?> subRequest, MOMutableTableRow currentRow, MOTableRow changeSet)
Prepares a row for changes described by the supplied change set. If the modification cannot be successfully prepared, the error status of the suppliedsubRequest
should be set to the appropriate error status value. This method is called only once per modified row.- Specified by:
prepareRow
in interfaceRowModificationControlColumn
- Parameters:
subRequest
- the sub-request that triggered the row change and that can be used to deny the commit phase by setting its error status.currentRow
- the current row (yet unmodified).changeSet
- a MOTableRow instance that represents the state of the row if all changes have been applied successfully.
-
isVolatile
public boolean isVolatile(MOTableRow row, int column)
Checks if the row is volatile (i.e. must not be stored in stable storage) or not. Note: In SNMP4J-Agent before 3.0, this method returned alsotrue
for rows with storage typereadOnly
which did not follow the SMI definition ofStorageType
. See alsoImportMode
for details about restore data from stable storage.- Overrides:
isVolatile
in classMOColumn<org.snmp4j.smi.Integer32>
- Parameters:
row
- a row of the table where this column is part of.column
- the column index of this column inrow
.- Returns:
true
if the storage type of this row isother
orvolatile_
.
