Constructor Detail

MBeanAttributeMOTableSupport

public MBeanAttributeMOTableSupport(MBeanServerConnection server)

Method Detail

add

public void add(org.snmp4j.smi.OID tableOID,
       MBeanAttributeMOTableInfo mBeanInfo)

Adds a table to MBean attributes mapping.

Parameters:

tableOID - the entry OID of the table (including the .1).

mBeanInfo - a MBeanAttributeMOTableInfo instance describing the actual mapping.

addAll

public void addAll(Object[][] tableDescriptions)

Adds a list of table to MBean attributes mappings.

Parameters:

tableDescriptions - an two dimensional array of table descriptions. Each description contains two elements:

1. the OID of the table entry (thus including the .1),
2. a MBeanAttributeMOTableInfo instance.

getLastIndex

public org.snmp4j.smi.OID getLastIndex(org.snmp4j.smi.OID tableOID)

Description copied from interface: JMXTableSupport

Gets the last SNMP index currently supported by the specified table.

Specified by:

getLastIndex in interface JMXTableSupport

Parameters:

tableOID - the OID of the table ManagedObject (including the .1 of the entry object) for which indexes are mapped.

Returns:

the last SNMP row index of the specified table.

getRow

public int getRow(org.snmp4j.smi.OID tableOID,
         org.snmp4j.agent.mo.MOTableRow row)

Description copied from interface: JMXTableSupport

Gets the row values for the specified row.

Specified by:

getRow in interface JMXTableSupport

Parameters:

tableOID - the OID of the table ManagedObject (including the .1 of the entry object) for which indexes are mapped.

row - a MOTableRow instance which will be modified to hold the SNMP values of the row specified by row's index value.

Returns:

a SNMP error status that indicates whether to operation succeeded or not.

setRow

public int setRow(org.snmp4j.smi.OID tableOID,
         org.snmp4j.agent.mo.MOTableRow row,
         int column)

Description copied from interface: JMXTableSupport

Sets the value of a column (cell) of a row from the corresponding SNMP conceptual row.

Specified by:

setRow in interface JMXTableSupport

Parameters:

tableOID - the OID of the table ManagedObject (including the .1 of the entry object) for which indexes are mapped.

row - a MOTableRow instance that identifies the target row by its row index (indirectly) and that contains the SNMP values that replace the corresponding native values.

column - the zero-based column index to set.

Returns:

a SNMP error status that indicates whether to operation succeeded or not.

isEmpty

public boolean isEmpty(org.snmp4j.smi.OID tableOID)

Description copied from interface: JMXTableSupport

Checks if the table is empty or not.

Specified by:

isEmpty in interface JMXTableSupport

Returns:

true if the table is empty (has no rows), false/code> otherwise.

getRowCount

public int getRowCount(org.snmp4j.smi.OID tableOID)

Description copied from interface: JMXTableSupport

Returns the number of rows of the specified table.

Specified by:

getRowCount in interface JMXTableSupport

Parameters:

tableOID - the OID of the table ManagedObject (including the .1 of the entry object) for which indexes are mapped.

Returns:

the number of rows in the table.

rowIdIterator

public Iterator rowIdIterator(org.snmp4j.smi.OID tableOID)

Description copied from interface: JMXTableSupport

Returns an Iterator over the row identifiers of the table.

Specified by:

rowIdIterator in interface JMXTableSupport

Parameters:

tableOID - the OID of the table ManagedObject (including the .1 of the entry object) for which indexes are mapped.

Returns:

an Iterator of row identifiers.

mapToIndex

public org.snmp4j.smi.OID mapToIndex(org.snmp4j.smi.OID tableOID,
                            Object nativeRowId,
                            int nativeIndex)

Description copied from interface: JMXTableSupport

Maps a native MBean row identifier object or index to a SNMP table index OID.

Specified by:

mapToIndex in interface JMXTableSupport

Parameters:

tableOID - the OID of the table ManagedObject (including the .1 of the entry object) for which indexes are mapped.

nativeRowId - the native row ID object which identifies the row. If null then nativeIndex identifies the row.

nativeIndex - the native enumerating index if rows are not identified by an object.

Returns:

the SNMP row index OID (suffix).

mapToRowId

public Object mapToRowId(org.snmp4j.smi.OID tableOID,
                org.snmp4j.smi.OID rowIndex)

Specified by:

mapToRowId in interface JMXTableSupport

Parameters:

tableOID - the OID of the table ManagedObject (including the .1 of the entry object) for which indexes are mapped.

rowIndex - a SNMP row index of the table specified by tableOID.

Returns:

a native row identifier.

rowIdTailIterator

public Iterator rowIdTailIterator(org.snmp4j.smi.OID tableOID,
                         Object firstRowId)

Description copied from interface: JMXTableSupport

Specified by:

rowIdTailIterator in interface JMXTableSupport

Parameters:

tableOID - the OID of the table ManagedObject (including the .1 of the entry object) for which indexes are mapped.

firstRowId - the lower bound (including) of the row identifiers to return.

Returns:

an Iterator of row identifiers.
