Detailed Description

Description of a node in a cluster.

This class holds the basic description of a node. It tells the name of the node and which file systems it has access to.

Currently the information is made persistent in a LOFAR .parset file. In the future it needs to use the Central Processor Resource Manager.

Member Enumeration Documentation

NodeType

enum dp3::common::NodeDesc::NodeType

Define the node types.

Constructor & Destructor Documentation

NodeDesc() [1/2]

dp3::common::NodeDesc::NodeDesc ( )

inline

Construct an empty object. By default its type is Any.

NodeDesc() [2/2]

dp3::common::NodeDesc::NodeDesc ( const ParameterSet &  )

explicit

Construct from the given parameterset.

Member Function Documentation

addFileSys()

void dp3::common::NodeDesc::addFileSys	(	const std::string &	fsName,
		const std::string &	mountPoint
	)

Add a file system the node has access to. A possible leading /auto is removed from the mountPoint.

findFileSys()

std::string dp3::common::NodeDesc::findFileSys

(

const std::string &

fileName

)

const

Find the file system a file is on. The file must be given with its absolute file name. It does it by comparing the mount points with the leading part of the file name.

getFileSys()

const std::vector<std::string>& dp3::common::NodeDesc::getFileSys ( ) const

inline

Get the file systems it has access to.

getMountPoints()

const std::vector<std::string>& dp3::common::NodeDesc::getMountPoints ( ) const

inline

Get the mount points of the file systems.

getName()

const std::string& dp3::common::NodeDesc::getName ( ) const

inline

Get the name.

getType()

NodeType dp3::common::NodeDesc::getType ( ) const

inline

Get the type.

setName()

void dp3::common::NodeDesc::setName ( const std::string &  name )

inline

Set node name.

setType()

void dp3::common::NodeDesc::setType ( NodeType  type )

inline

Set node type.

write()

void dp3::common::NodeDesc::write	(	std::ostream &	os,
		const std::string &	prefix
	)		const

Write it in parset format.
