Detailed Description

This class contains information on the configuration, i.e set of nodes or simply site definition.

Users are responsible for guaranteeing that information encapsulated by different Gcs_xcom_nodes is properly defined. In the sense that the member identifier, the unique identifier and the address uniquely identify a node and the same holds for any combination of those three.

Nodes inserted in this set are copied and stored in a vector object. Currently, we don't check whether the same node is inserted twice or not and as such duplicated entries are allowed. Users are responsible for guaranteeing that duplicated entries are not inserted.

Gcs_xcom_nodes::Gcs_xcom_nodes ( const site_def site,
node_set &  nodes 
)
explicit

Constructor that reads the site definition and whether a node is considered dead or alive to build a list of addresses and statuses.

◆ ~Gcs_xcom_nodes()

Clear up the current set and add a new set of nodes.

Parameters
xcom_nodesSet of nodes.

◆ clear_nodes()

void Gcs_xcom_nodes::clear_nodes ( )

Clear the set of nodes.

◆ empty()

bool Gcs_xcom_nodes::empty ( ) const

Whether the set of nodes is empty or not.

◆ encode()

bool Gcs_xcom_nodes::encode ( unsigned int *  ptr_size,
char ***  ptr_addrs,
blob **  ptr_uuids

◆ get_node() [3/4]

const Gcs_xcom_node_information * Gcs_xcom_nodes::get_node ( const std::string &  member_id) const

Return a pointer to a node if it exists, otherwise NULL.

◆ get_node() [4/4]

const Gcs_xcom_node_information * Gcs_xcom_nodes::get_node ( unsigned int  node_no) const

Return a pointer to a node if it exists, otherwise NULL.

unsigned int Gcs_xcom_nodes::get_node_no ( ) const

Return the index of the current node (i.e.

member).

◆ get_nodes()

const std::vector< Gcs_xcom_node_information > & Gcs_xcom_nodes::get_nodes ( ) const

Return a reference to the addresses' vector.

unsigned int Gcs_xcom_nodes::get_size ( ) const

Return the number of nodes in the set.

◆ is_valid()

bool Gcs_xcom_nodes::is_valid ( ) const
inline

Return with the configuration is valid or not.
