Detailed Description

Singleton that caches per-node incoming/outgoing ExecPinConnection lists.

Typical usage:

auto& lc = LinkCache::Get();
lc.Rebuild(myTemplate.ExecConnections);
const auto& out = lc.GetOutgoing(nodeId);
const auto& in  = lc.GetIncoming(nodeId);

GetConnectionCount()

int Olympe::LinkCache::GetConnectionCount

(

)

const

Returns the total number of connections stored in the cache.

GetIncoming()

const std::vector< ExecPinConnection > & Olympe::LinkCache::GetIncoming

(

int

nodeId

)

const

Returns the list of connections that terminate at nodeId.

Returns an empty vector if the node has no incoming connections.

GetOutgoing()

const std::vector< ExecPinConnection > & Olympe::LinkCache::GetOutgoing

(

int

nodeId

)

const

Returns the list of connections that originate from nodeId.

Returns an empty vector if the node has no outgoing connections.

Invalidate()

void Olympe::LinkCache::Invalidate

IsValid()

bool Olympe::LinkCache::IsValid

(

)

const

Returns true if the cache has been built and is not stale.

Rebuild()

void Olympe::LinkCache::Rebuild

(

const std::vector< ExecPinConnection > &

connections

)

Rebuilds both outgoing and incoming maps from the supplied list.

Parameters

connections

Flat list of exec-pin connections (e.g. from a TaskGraphTemplate).
