Detailed Description

Set of recovered servers.

This class maintains the set of proxy names of servers that have been recovered. It is used to ensure that a server does not inadvertently get recovered twice.

Constructor & Destructor Documentation

RecoveredServers::RecoveredServers ( )

Default constructor.

This constructor constructs an empty object.

Definition at line 38 of file RecoveredServers.cc.

RecoveredServers::RecoveredServers ( const MetaLog::EntityHeader & header )

Constructor with MetaLog header.

This constructor constructs an empty object to be populated by an MML entity.

Parameters

header MML entity header

Definition at line 42 of file RecoveredServers.cc.

virtual Hypertable::RecoveredServers::~RecoveredServers ( )

inlinevirtual

Destructor.

Definition at line 58 of file RecoveredServers.h.

Member Function Documentation

void RecoveredServers::add ( const std::string & location )

Adds proxy name to recovered servers set.

Parameters

location Proxy name of recovered server

Definition at line 46 of file RecoveredServers.cc.

bool RecoveredServers::contains ( const std::string & location )

Check to see if proxy name is in recovered servers set.

Parameters

location Proxy name of server to check

Returns: true if server identified by location is in the recovered servers set, false otherwise.

Definition at line 51 of file RecoveredServers.cc.

void RecoveredServers::decode	(	const uint8_t **	bufp,
		size_t *	remainp,
		uint16_t	definition_version
	)

overrideprivatevirtual

MetaLog entity decode method.

Reimplemented from Hypertable::MetaLog::Entity.

Definition at line 80 of file RecoveredServers.cc.

void RecoveredServers::decode_internal	(	uint8_t	version,
		const uint8_t **	bufp,
		size_t *	remainp
	)

overrideprivatevirtual

Reads serialized representation of object from a buffer.

Parameters

version	Encoding version
bufp	Address of destination buffer pointer (advanced by call)
remainp	Address of integer holding amount of serialized object remaining
