Method Detail

findRootByNodeId

OnmsHwEntity findRootByNodeId(Integer nodeId)

Find root by node id.

Parameters:

nodeId - the node id

Returns:

the OpenNMS hardware entity

findRootEntityByNodeId

OnmsHwEntity findRootEntityByNodeId(Integer nodeId)

Better performant than #findRootByNodeId. Useful when dealing with large trees. See NMS-13256 Find root by node id

Parameters:

nodeId - the node id

Returns:

the OpenNMS hardware entity

findEntityByIndex

OnmsHwEntity findEntityByIndex(Integer nodeId,
                               Integer entPhysicalIndex)

Find entity by index.

Parameters:

nodeId - the node id

entPhysicalIndex - the entity physical index

Returns:

the OpenNMS hardware entity

findEntityByName

OnmsHwEntity findEntityByName(Integer nodeId,
                              String entPhysicalName)

Find entity by name.

Parameters:

nodeId - the node id

entPhysicalName - the entity physical name

Returns:

the OpenNMS hardware entity

getAttributeValue

String getAttributeValue(Integer nodeId,
                         Integer entPhysicalIndex,
                         String attributeName)

Gets the attribute value.

Parameters:

nodeId - the node id

entPhysicalIndex - the entity physical index

attributeName - the name of the desired attribute

Returns:

the attribute value

getAttributeValue

String getAttributeValue(Integer nodeId,
                         String nameSource,
                         String attributeName)

Gets the attribute value.

Parameters:

nodeId - the node id

nameSource - either the value of entPhysicalName or a regular expression to be applied over the entPhysicalName (should start with '~')

attributeName - the name of the desired attribute

Returns:

the attribute value
