unbounded_buffer Class

Other Versions

An unbounded_buffer messaging block is a multi-target, multi-source, ordered propagator_block capable of storing an unbounded number of messages.

Syntax

template<
   class _Type
>
class unbounded_buffer : public propagator_block<multi_link_registry<ITarget<_Type>>, multi_link_registry<ISource<_Type>>>;

Parameters

_Type: The payload type of the messages stored and propagated by the buffer.

Members

Public Constructors

Name	Description
unbounded_buffer::unbounded_buffer Constructor	Overloaded. Constructs an unbounded_buffer messaging block.
unbounded_buffer::~unbounded_buffer Destructor	Destroys the unbounded_buffer messaging block.

Public Methods

Name	Description
unbounded_buffer::dequeue Method	Removes an item from the unbounded_buffer messaging block.
unbounded_buffer::enqueue Method	Adds an item to the unbounded_buffer messaging block.

Protected Methods

Name	Description
unbounded_buffer::accept_message Method	Accepts a message that was offered by this unbounded_buffer messaging block, transferring ownership to the caller.
unbounded_buffer::consume_message Method	Consumes a message previously offered by the unbounded_buffer messaging block and reserved by the target, transferring ownership to the caller.
unbounded_buffer::link_target_notification Method	A callback that notifies that a new target has been linked to this unbounded_buffer messaging block.
unbounded_buffer::process_input_messages Method	Places the message_PMessage in this unbounded_buffer messaging block and tries to offer it to all of the linked targets.
unbounded_buffer::propagate_message Method	Asynchronously passes a message from an ISource block to this unbounded_buffer messaging block. It is invoked by the propagate method, when called by a source block.
unbounded_buffer::propagate_output_messages Method	Places the message_PMessage in this unbounded_buffer messaging block and tries to offer it to all of the linked targets. (Overrides source_block::propagate_output_messages.)
unbounded_buffer::release_message Method	Releases a previous message reservation. (Overrides source_block::release_message.)
unbounded_buffer::reserve_message Method	Reserves a message previously offered by this unbounded_buffer messaging block. (Overrides source_block::reserve_message.)
unbounded_buffer::resume_propagation Method	Resumes propagation after a reservation has been released. (Overrides source_block::resume_propagation.)
unbounded_buffer::send_message Method	Synchronously passes a message from an ISource block to this unbounded_buffer messaging block. It is invoked by the send method, when called by a source block.
unbounded_buffer::supports_anonymous_source Method	Overrides the supports_anonymous_source method to indicate that this block can accept messages offered to it by a source that is not linked. (Overrides ITarget::supports_anonymous_source.)
