sc::ThreadGrp(3) MPQC sc::ThreadGrp(3) NAME sc::ThreadGrp - The ThreadGrp abstract class provides a means to manage separate threads of control. SYNOPSIS #include <thread.h> Inherits sc::DescribedClass. Inherited by sc::ProcThreadGrp, sc::PthreadThreadGrp, and sc::PumaThread- Grp. Public Member Functions ThreadGrp (const Ref< KeyVal > &) ThreadGrp (const ThreadGrp &, int nthread=-1) virtual void add_thread (int threadnum, Thread *thread) Assigns a Thread object to each thread. virtual void add_thread (int threadnum, Thread *thread, int priority) Like add_thread(threadnum, thread), but assign a priority that the thread is to use. int nthread () const The number of threads that will be run by start_thread. void delete_threads () virtual int start_threads ()=0 Starts the threads running. virtual int wait_threads ()=0 Wait for all the threads to complete. virtual Ref< ThreadLock > new_lock ()=0 Return a local object. virtual ThreadGrp * clone (int nthread=-1) Create a ThreadGrp like the current one. Public Member Functions inherited from sc::DescribedClass DescribedClass (const DescribedClass &) DescribedClass & operator= (const DescribedClass &) ClassDesc * class_desc () const throw () This returns the unique pointer to the ClassDesc corresponding to the given type_info object. const char * class_name () const Return the name of the object's exact type. int class_version () const Return the version of the class. virtual void print (std::ostream &=ExEnv::out0()) const Print the object. Public Member Functions inherited from sc::RefCount int lock_ptr () const Lock this object. int unlock_ptr () const Unlock this object. void use_locks (bool inVal) start and stop using locks on this object refcount_t nreference () const Return the reference count. refcount_t reference () Increment the reference count and return the new count. refcount_t dereference () Decrement the reference count and return the new count. int managed () const void unmanage () Turn off the reference counting mechanism for this object. int managed () const Return 1 if the object is managed. Otherwise return 0. Public Member Functions inherited from sc::Identity Identifier identifier () Return the Identifier for this argument. Static Public Member Functions static void set_default_threadgrp (const Ref< ThreadGrp > &) static ThreadGrp * get_default_threadgrp () static ThreadGrp * initial_threadgrp (int &argc, char **argv) Protected Attributes Thread ** threads_ int nthread_ Additional Inherited Members Protected Member Functions inherited from sc::RefCount RefCount (const RefCount &) RefCount & operator= (const RefCount &) Detailed Description The ThreadGrp abstract class provides a means to manage separate threads of control. Member Function Documentation virtual void sc::ThreadGrp::add_thread (int threadnum, Thread * thread) [vir- tual] Assigns a Thread object to each thread. If 0 is assigned to a thread, then that thread will be skipped. Reimplemented in sc::PthreadThreadGrp. Referenced by sc::PthreadThreadGrp::add_thread(). virtual void sc::ThreadGrp::add_thread (int threadnum, Thread * thread, int priority) [virtual] Like add_thread(threadnum, thread), but assign a priority that the thread is to use. The member is primarily for experimentation, the priority argu- ment is currently not well defined and ignored. Reimplemented in sc::PthreadThreadGrp. virtual ThreadGrp * sc::ThreadGrp::clone (int nthread = -1) [virtual] Create a ThreadGrp like the current one. If nthread is given, the new ThreadGrp will attempt to support that number of threads, but the actual number supported may be less. If nthread is -1, the number of threads in the current group will be used. Reimplemented in sc::PthreadThreadGrp, and sc::ProcThreadGrp. virtual Ref< ThreadLock > sc::ThreadGrp::new_lock () [pure virtual] Return a local object. Implemented in sc::PthreadThreadGrp, sc::PumaThreadGrp, and sc::ProcThread- Grp. virtual int sc::ThreadGrp::start_threads () [pure virtual] Starts the threads running. Thread 0 will be run by the thread that calls start_threads. Implemented in sc::PthreadThreadGrp, sc::PumaThreadGrp, and sc::ProcThread- Grp. virtual int sc::ThreadGrp::wait_threads () [pure virtual] Wait for all the threads to complete. This must be called before start_threads is called again or the object is destroyed. Implemented in sc::PthreadThreadGrp, sc::PumaThreadGrp, and sc::ProcThread- Grp.
