Component Manager
Application Framework

The Component Manager API provides functions to get information about installed or running components and manage the components.

Required Header

#include <component_manager.h>

Overview

The Component Manager API provides functions to retrieve components information and to manager components. There are two iterator functions that retrieve components. One is component_manager_foreach_component_context(), which gets the information of running components, the other is component_manager_foreach_component_info(), which gets the information of installed components. The registered callback function is called as much as components exist in the list. An application can get the component's properties such as a name, a type, an icon path in the callback function. Resuming components or terminating background components are also supported to handle components.

Functions

int component_manager_foreach_component_context (component_manager_component_context_cb callback, void *user_data)
 Retrieves all component contexts of running components.
int component_manager_foreach_component_info (component_manager_component_info_cb callback, void *user_data)
 Retrieves all installed components information.
int component_manager_get_component_context (const char *comp_id, component_context_h *handle)
 Gets the component context for the given component ID.
int component_manager_get_component_info (const char *comp_id, component_info_h *handle)
 Gets the component information for the given component ID.
int component_manager_is_running (const char *comp_id, bool *running)
 Checks whether the component is running or not.
int component_manager_resume_component (component_context_h handle)
 Resumes the component.
int component_manager_terminate_bg_component (component_context_h handle)
 Terminates the background component.

Typedefs

typedef bool(* component_manager_component_context_cb )(component_context_h handle, void *user_data)
 Called whenever the application retrieves the context of running components.
typedef bool(* component_manager_component_info_cb )(component_info_h handle, void *user_data)
 Called whenever the application retrieves the information of installed components.

Typedef Documentation

typedef bool(* component_manager_component_context_cb)(component_context_h handle, void *user_data)

Called whenever the application retrieves the context of running components.

Since :
5.5
Remarks:
The handle should not be released. The handle can be used only in the callback. To use outside, make a copy using component_context_clone().
Parameters:
[in]handleThe component context of each running component
[in]user_dataThe user data passed from the foreach function
Returns:
true to continue with the next iteration of the loop,
otherwise false to break out of the loop
Precondition:
component_manager_foreach_component_context() will invoke this callback.
See also:
component_manager_foreach_component_context()
typedef bool(* component_manager_component_info_cb)(component_info_h handle, void *user_data)

Since :
5.5
Remarks:
The handle should not be released. The handle can be used only in the callback. To use outside, make a copy using component_info_clone().
Parameters:

[in]user_dataThe user data passed from the foreach function
Returns:
true to continue with the next iteration of the loop,
otherwise false to break out of the loop
