Thread::Isolate::Map - Map/link packages of one thread to many other threads.

The idea of this module is to map a package of one thread to many other threads, saving memory through many threads.

Thread::Isolate::Map supports map for SCALAR, ARRAY, HASH, HANDLE (IO) and CODE symbols.

  use Thread::Isolate ; ## Is recomended to load it before to save memory.
  use Thread::Isolate::Map ;

  my $thi = Thread::Isolate->new() ;

  $thi->eval(q`
    package Foo ;
      $FOOVAL = 0 ;
  `) ;

  my $thi1 = Thread::Isolate->new() ;
  my $thi2 = Thread::Isolate->new() ;

  $thi1->map_package('Foo',$thi) ;
  $thi2->map_package('Foo',$thi) ;

  $thi1->eval('$Foo::FOOVAL = 10 ;');  ## $FOOVAL is 10 now. (thi1)

  $thi2->eval('$Foo::FOOVAL += 10 ;'); ## $FOOVAL is 20 now. (thi2)

  $thi->eval('return $Foo::FOOVAL'); ## returns 20. (thi)

As you can see in the code above all the 3 threads share the same package, and the package symbols like $FOOVAL.

Maps a local package to a thread package.

PACKAGE

The package to map.

THREAD

The Thread::Isolate object that has the real package.

Scan the symbol table entries of a package.

THREAD?

If defined will scan the package inside the thread.

PACKAGE

The package to scan.

RECURSIVE

If TRUE will do a recursive scan, getting symbols of sub-packages.

All the mapped HANDLEs (IO) will be automatically flushed ($| = 1), since is not possible to flush from an external thread, also will avoid lose of output data when the HANDLE is not closed explicity when the process goes out.

Thread::Isolate, Thread::Isolate::Pool.
