Detailed Description

The Module class. The browser calls CreateInstance() to create an instance of your module on the web page. The browser creates a new instance for each <embed> tag with type="application/x-nacl"

Member Function Documentation

void pp::Module::AddPluginInterface	(	const std::string &	interface_name,
		const void *	vtable
	)

AddPluginInterface() adds a handler for a provided interface name. When the browser requests that interface name, the provided vtable will be returned.

In general, modules will not need to call this directly. Instead, the C++ wrappers for each interface will register themselves with this function.

This function may be called more than once with the same interface name and vtable with no effect. However, it may not be used to register a different vtable for an already-registered interface. It will assert for a different registration for an already-registered interface in debug mode, and just ignore the registration in release mode.

Parameters

[in]	interface_name	The interface name that will receive a handler.
[in,out]	vtable	The vtable to return for interface_name.

Core* pp::Module::core ( )

inline

The core() function returns the core interface for doing basic global operations. The return value is guaranteed to be non-NULL once the module has successfully initialized and during the Init() call.

It will be NULL before Init() has been called.

Returns

The core interface for doing basic global operations.

virtual Instance* pp::Module::CreateInstance ( PP_Instance  instance )

protectedpure virtual

CreateInstance() should be overridden to create your own module type.

Parameters

[in]

instance

A PP_Instance.

Returns

The resulting instance.

const InstanceMap& pp::Module::current_instances ( ) const

inline

The current_instances() function allows iteration over the current instances in the module.

Returns

An InstanceMap of all instances in the module.

static Module* pp::Module::Get ( )

static

Get() returns the global instance of this module object, or NULL if the module is not initialized yet.

Returns

The global instance of the module object.

PPB_GetInterface pp::Module::get_browser_interface ( ) const

inline

The get_browser_interface() function returns the internal get_browser_interface pointer.

Returns

A PPB_GetInterface internal pointer.

const void* pp::Module::GetBrowserInterface

(

const char *

interface_name

)

GetBrowserInterface() returns interfaces which the browser implements (i.e. PPB interfaces).

Parameters

[in]

interface_name

The browser interface for the module to get.

const void* pp::Module::GetPluginInterface

(

const char *

interface_name

)

GetPluginInterface() implements GetInterface for the browser to get module interfaces. If you need to provide your own implementations of new interfaces, use AddPluginInterface() which this function will use.

Parameters

[in]

interface_name

The module interface for the browser to get.

virtual bool pp::Module::Init ( )

virtual

Init() is automatically called after the object is created. This is where you can put functions that rely on other parts of the API, now that the module has been created.

Returns

true if successful, otherwise false.

Instance* pp::Module::InstanceForPPInstance

(

PP_Instance

instance

)

InstanceForPPInstance() returns the object associated with this PP_Instance, or NULL if one is not found. This should only be called from the main thread! This instance object may be destroyed at any time on the main thread, so using it on other threads may cause a crash.

Parameters

[in]

instance

This PP_Instance.

Returns

The object associated with this PP_Instance, or NULL if one is not found.

bool pp::Module::InternalInit	(	PP_Module	mod,
		PPB_GetInterface	get_browser_interface
	)

function that can be overridden by the base classes.

Parameters

[in]	mod	A PP_Module.
[in]	get_browser_interface	The browser interface to set.

Returns

true if successful, otherwise false.

PP_Module pp::Module::pp_module ( ) const

inline

The pp_module() function returns the internal module handle.

Returns

A PP_Module internal module handle.
