Detailed Description

Default scheduler use in Hedgehog graph.

By default, each node that needs a thread gets a thread and management of these threads is left to the OS.

Definition of virtual constructor.

Returns

New instance of DefaultScheduler

Implements hh::Scheduler.

Definition at line 57 of file default_scheduler.h.

joinAll()

void hh::DefaultScheduler::joinAll ( )

inlineoverridevirtual

Wait for all inside nodes to join and join the threads of all inside graphs.

Implements hh::Scheduler.

Definition at line 96 of file default_scheduler.h.

spawnThreads()

void hh::DefaultScheduler::spawnThreads ( std::set< core::abstraction::NodeAbstraction * > const &  cores, bool  waitForInitialization  )

inlineoverridevirtual

Spawn the threads for all graph's nodes.

Parameters

cores	Graph's inside nodes
waitForInitialization	Wait for internal nodes to be initialized flags

Exceptions

std::runtime_error

if a thread cannot be created, or if the core is malformed

If asked, wait for all internals to be initialized before returning

Implements hh::Scheduler.
