Method Detail

mapToIndex

public org.snmp4j.smi.OID mapToIndex(java.lang.Object rowIdentifier)

Description copied from interface: JMXIndexSupport

Maps a row identifier (i.e., an Object returned by JMXIndexSupport.getRowIdentifier(java.lang.Object, int)) to a row index.

Specified by:

mapToIndex in interface JMXIndexSupport

Parameters:

rowIdentifier - an Object describing a row index.

Returns:

a row index OID.

allocateNewIndex

protected org.snmp4j.smi.OID allocateNewIndex(java.lang.Object rowIdentifier)

mapToRowMBean

public abstract javax.management.ObjectName mapToRowMBean(java.lang.Object rowIdentifier)

Description copied from interface: JMXIndexSupport

Maps a row identifier to a MBean object name. If a row cannot be accessed directly via an index, for example, because the rows are mapped from a list or array, then null is returned.

Specified by:

mapToRowMBean in interface JMXIndexSupport

Parameters:

rowIdentifier - the row identifier which may be also a native index value into an array or list of MBean attribute values.

Returns:

ObjectName the object name of the MBean representing the row identified by rowIdentifier. If rowIdentifier is a Integer and null is returned, the caller should use the rowIdentifier value as index into the value list.

mapToRowIdentifier

public java.lang.Object mapToRowIdentifier(org.snmp4j.smi.OID rowIndex)

Description copied from interface: JMXIndexSupport

Maps a row index OID to an object describing a row index internally.

Specified by:

mapToRowIdentifier in interface JMXIndexSupport

Parameters:

rowIndex - a row index OID.

Returns:

an Object describing a row index.

getRowIdentifier

public java.lang.Object getRowIdentifier(java.lang.Object nativeRowId,
                                         int nativeRowIndex)

Description copied from interface: JMXIndexSupport

Maps a native object identifying a row or alternatively the row's index into an internal array (e.g., an array returned by a MBean method).

Specified by:

getRowIdentifier in interface JMXIndexSupport

Parameters:

nativeRowId - an Object identifying a row.

nativeRowIndex - optionally the index of the row into an internal array.

Returns:

a key Object that can be directly mapped to a row index OID.
