Detailed Description

template<class runtime_cfg_t>
class MHAPlugin::plugin_t< runtime_cfg_t >

The template class for C++ openMHA plugins.

Template Parameters

runtime_cfg_t run-time configuration.

This template class provides thread safe configuration handling and standard methods to be compatible to the C++ openMHA plugin wrapper macro MHAPLUGIN_CALLBACKS.

The template parameter runtime_cfg_t should be the runtime configuration of the plugin.

See MHAPlugin::config_t for details on the thread safe communication update mechanism.

Constructor & Destructor Documentation

◆ plugin_t()

template<class runtime_cfg_t >

MHAPlugin::plugin_t< runtime_cfg_t >::plugin_t	(	const std::string &	help,
		MHA_AC::algo_comm_t &	iac
	)

Constructor of plugin template base class.

Plugin classes inherit from MHAPlugin::plugin_t<> and will call this base class constructor in their constructor's initialization list.

The constructor of a plugin is called each time a plugin is loaded into MHA: Multiple instances of the same plugin can be loaded and for each plugin instance, a new instance of the plugin class will be created.

Parameters

help	Short help text that provides some general information about the plugin. This text is returned in response to configuration language query command "?help".
iac	AC space handle (will be stored into the member variable ac).

◆ ~plugin_t()

template<class runtime_cfg_t >

MHAPlugin::plugin_t< runtime_cfg_t >::~plugin_t

virtual

Destructor of plugin template base class.

Plugin class instances are deleted and the destructor of the instance is called when unloading a plugin instance from the MHA. Typically this happens just before the MHA process terminates, e.g. in response to cmd=quit, but some plugins also have the capability of replacing loaded plugins during runtime of the MHA, in which case the destructor of the active instances is called before the unloading.

In some exceptional cases, e.g. when an error occurs during initializing the MHA, the MHA process may terminate without ever calling the destructors of all existing plugin instances.

Member Data Documentation

◆ tftype

template<class runtime_cfg_t >

mhaconfig_t MHAPlugin::plugin_t< runtime_cfg_t >::tftype

protected

Member for storage of plugin interface configuration.

This member is defined for convenience of the developer. Typically, the actual contents of mhaconfig_t are stored in this member in the prepare() method.

Note: This member is likely to be removed in later versions, use input_cfg() and output_cfg() instead.

◆ ac

template<class runtime_cfg_t >

MHA_AC::algo_comm_t& MHAPlugin::plugin_t< runtime_cfg_t >::ac

protected

AC handle of the chain.

This variable is initialized in the constructor and can be used by derived plugins to access the AC space. Its contents should not be modified.
