target_block Class

2012-07-10

The target_block class is an abstract base class that provides basic link management functionality and error checking for target only blocks.

template<
   class _SourceLinkRegistry,
   class _MessageProcessorType = ordered_message_processor<typename _SourceLinkRegistry::type::source_type>
>
class target_block : public ITarget<typename _SourceLinkRegistry::type::source_type>;

Parameters

_SourceLinkRegistry
The link registry to be used for holding the source links.
_MessageProcessorType
The processor type for message processing.

Members

Public Typedefs

Name	Description
source_iterator	The type of the iterator for the source_link_manager for this target_block object.

Public Constructors

Name	Description
target_block::target_block Constructor	Constructs a target_block object.
target_block::~target_block Destructor	Destroys the target_block object.

Public Methods

Name	Description
target_block::propagate Method	Asynchronously passes a message from a source block to this target block.
target_block::send Method	Synchronously passes a message from a source block to this target block.

Protected Methods

Name	Description
target_block::async_send Method	Asynchronously sends a message for processing.
target_block::decline_incoming_messages Method	Indicates to the block that new messages should be declined.
target_block::enable_batched_processing Method	Enables batched processing for this block.
target_block::initialize_target Method	Initializes the base object. Specifically, the message_processor object needs to be initialized.
target_block::link_source Method	Links a specified source block to this target_block object.
target_block::process_input_messages Method	Processes messages that are received as inputs.
target_block::process_message Method	When overridden in a derived class, processes a message that was accepted by this target_block object.
target_block::propagate_message Method	When overridden in a derived class, this method asynchronously passes a message from an ISource block to this target_block object. It is invoked by the propagate method, when called by a source block.
target_block::register_filter Method	Registers a filter method that will be invoked on every message received.
target_block::remove_sources Method	Unlinks all sources after waiting for outstanding asynchronous send operations to complete.
target_block::send_message Method	When overridden in a derived class, this method synchronously passes a message from an ISource block to this target_block object. It is invoked by the send method, when called by a source block.
target_block::sync_send Method	Synchronously send a message for processing.
target_block::unlink_source Method	Unlinks a specified source block from this target_block object.
target_block::unlink_sources Method	Unlinks all source blocks from this target_block object. (Overrides ITarget::unlink_sources.)
target_block::wait_for_async_sends Method	Waits for all asynchronous propagations to complete.
