Member Function Documentation

◆ as_mbox()

mbox_t so_5::abstract_message_chain_t::as_mbox ( )

Cast message chain to message box.

◆ close()

virtual void so_5::abstract_message_chain_t::close ( mchain_props::close_mode_t mode )

pure virtual

Close the chain.

Parameters

mode	What to do with chain's content.

Implemented in so_5::mchain_props::mchain_template< Queue, Tracing_Base >.

◆ empty()

virtual bool so_5::abstract_message_chain_t::empty ( ) const

pure virtual

Is message chain empty?

Implemented in so_5::mchain_props::mchain_template< Queue, Tracing_Base >.

Examples:: so_5/producer_consumer_mchain/main.cpp.

◆ environment()

virtual so_5::environment_t& so_5::abstract_message_box_t::environment

noexcept

SObjectizer Environment for which the mbox is created.

Since: v.5.6.0

◆ extract() [1/2]

virtual mchain_props::extraction_status_t so_5::abstract_message_chain_t::extract	(	mchain_props::demand_t &	dest,
		mchain_props::duration_t	empty_queue_timeout
	)

pure virtual

Parameters

dest	Destination for extracted messages.
empty_queue_timeout	Max time to wait on empty queue.

Implemented in so_5::mchain_props::mchain_template< Queue, Tracing_Base >.

◆ extract() [2/2]

mchain_props::extraction_status_t so_5::abstract_message_chain_t::extract	(	mchain_props::demand_t &	dest,
		mchain_props::select_case_t &	select_case
	)

protectedvirtual

An extraction attempt as a part of multi chain select.

Note: In v.5.5.16 this method has an implementation. It is done to keep compatibility with previous version. This implementation throws an exception.; This method is intended to be used by select_case_t.

Since: v.5.5.16

Parameters

dest	Destination for extracted messages.
select_case	Select case to be stored for notification if mchain is empty.

Reimplemented in so_5::mchain_props::mchain_template< Queue, Tracing_Base >.

◆ id()

virtual mbox_id_t so_5::abstract_message_box_t::id

Unique ID of this mbox.

Since: v.5.4.0

◆ operator=()

abstract_message_chain_t& so_5::abstract_message_chain_t::operator= ( const abstract_message_chain_t & )

privatedelete

◆ remove_from_select()

void so_5::abstract_message_chain_t::remove_from_select ( mchain_props::select_case_t & select_case )

protectedvirtual

Removement of mchain from multi chain select.

Note: In v.5.5.16 this method has an implementation. It is done to keep compatibility with previous version. This implementation throws an exception.; This method is intended to be used by select_case_t.

Attention: This method will be declared as pure virtual and noexcept in v.5.6.0.

Since: v.5.5.16

Parameters

select_case Select case to be removed from notification queue.

Reimplemented in so_5::mchain_props::mchain_template< Queue, Tracing_Base >.

◆ size()

virtual std::size_t so_5::abstract_message_chain_t::size ( ) const

pure virtual

Count of messages in the chain.

Implemented in so_5::mchain_props::mchain_template< Queue, Tracing_Base >.
