Detailed Description

template<typename T>
class stapl::runtime::broadcast_object< T >

Performs a broadcast over all locations of the current gang.

Template Parameters

T	Object type.

Member Function Documentation

wait() [1/2]

void stapl::runtime::value_handle< T >::wait ( void  ) const

finalvirtualinherited

Waits for the result to be received.

Blocks until valid() const returns true.

Implements stapl::runtime::future_base< T >.

wait() [2/2]

void stapl::runtime::value_handle< T >::wait ( context &  ctx ) const

inherited

Waits for the result to be received.

Blocks until valid() const returns true.

get() [1/2]

T stapl::runtime::value_handle< T >::get ( void  )

finalvirtualinherited

Returns the received result.

This function waits until the result has been received and returns it.

Calling valid() const returns false after a call to this function.

The lock ensures that set_value() has finished before the get() continues, to avoid calling schedule_continuation() on an object that has been destroyed.

Implements stapl::runtime::future_base< T >.

get() [2/2]

T stapl::runtime::value_handle< T >::get ( context &  ctx )

inherited

Returns the received result.

This function waits until the result has been received and returns it.

Calling valid() const returns false after a call to this function.

The lock ensures that set_value() has finished before the get() continues, to avoid calling schedule_continuation() on an object that has been destroyed.

set_value() [1/3]

void stapl::runtime::value_handle< T >::set_value ( storage_type *const  p, void *const  base, message_shared_ptr &  m  )

inherited

Sets the result.

This function keeps a pointer to the buffer where the result remains packed until get() is called.

Parameters

p	Pointer to the stapl::runtime::arg_storage in the buffer.
base	Address in the buffer that the stapl::runtime::arg_storage is stored in.
m	Buffer that contains the stapl::runtime::arg_storage.

arg_storage, message

set_value() [2/3]

void stapl::runtime::value_handle< T >::set_value ( T const &  value )

inherited

Sets the result.

Parameters

value

Value to be set.

set_value() [3/3]

void stapl::runtime::value_handle< T >::set_value ( T &&  value )

inherited
