Member Function Documentation

BDM_CLASS_DEF_NV()

bdm::AgentUidGenerator::BDM_CLASS_DEF_NV ( AgentUidGenerator  , 1    )

private

GenerateUid()

AgentUid bdm::AgentUidGenerator::GenerateUid ( )

inline

Generates AgentUid with increasing index. In defragmentation mode it reuses index values from removed agents and increments the reused field. Thread-safe.

Definition at line 44 of file agent_uid_generator.h.

GetHighestIndex()

AgentUid::Index_t bdm::AgentUidGenerator::GetHighestIndex ( ) const

inline

Thread-safe.

Definition at line 56 of file agent_uid_generator.h.

ReuseAgentUid()

void bdm::AgentUidGenerator::ReuseAgentUid ( const AgentUid &  uid )

inline

Adds AgentUid that can be reused after AgentUid::reused_ is incremented. Thread-safe.

Definition at line 60 of file agent_uid_generator.h.

Update()

void bdm::AgentUidGenerator::Update ( )

inline

Resizes internal data structures to the number of threads. NB: If Update is called, calls to GenerateUid or ReuseAgentUid are not allowed!

Definition at line 67 of file agent_uid_generator.h.

Member Data Documentation

counter_

std::atomic<typename AgentUid::Index_t> bdm::AgentUidGenerator::counter_

private

Definition at line 70 of file agent_uid_generator.h.

root_counter_

AgentUid::Index_t bdm::AgentUidGenerator::root_counter_

private

ROOT can't persist std::atomic. Therefore this additional helper variable is needed.

Definition at line 73 of file agent_uid_generator.h.

tinfo_

ThreadInfo* bdm::AgentUidGenerator::tinfo_ = nullptr

private

Definition at line 77 of file agent_uid_generator.h.

tl_uids_

SharedData<std::vector<AgentUid> > bdm::AgentUidGenerator::tl_uids_

private

Thread local vector of AgentUids that can be reused.
