void pp::Core::AddRefResource ( PP_Resource resource )

inline

AddRefResource() increments the reference count for the provided resource.

Parameters

[in] resource A PP_Resource corresponding to a resource.

void pp::Core::CallOnMainThread	(	int32_t	delay_in_milliseconds,
		const CompletionCallback &	callback,
		int32_t	result = `0`
	)

CallOnMainThread() schedules work to be executed on the main pepper thread after the specified delay. The delay may be 0 to specify a call back as soon as possible.

The |result| parameter will just be passed as the second argument to the callback. Many applications won't need this, but it allows a module to emulate calls of some callbacks which do use this value.

Note: CallOnMainThread(), even when used from the main thread with a delay of 0 milliseconds, will never directly invoke the callback. Even in this case, the callback will be scheduled asynchronously.

Note: If the browser is shutting down or if the module has no instances, then the callback function may not be called.

Parameters

[in]	delay_in_milliseconds	An int32_t delay in milliseconds.
[in]	callback	A `CompletionCallback` callback function that the browser will call after the specified delay.
[in]	result	An int32_t that the browser will pass to the given `CompletionCallback`.

PP_Time pp::Core::GetTime ( )

inline

GetTime() returns the "wall clock time" according to the browser.

Returns: A PP_Time containing the "wall clock time" according to the browser.

PP_TimeTicks pp::Core::GetTimeTicks ( )

inline

GetTimeTicks() returns the "tick time" according to the browser. This clock is used by the browser when passing some event times to the module (for example, using the PP_InputEvent::time_stamp_seconds field). It is not correlated to any actual wall clock time (like GetTime()). Because of this, it will not change if the user changes their computer clock.

Returns: A PP_TimeTicks containing the "tick time" according to the browser.

bool pp::Core::IsMainThread ( )

IsMainThread() returns true if the current thread is the main pepper thread.

This function is useful for implementing sanity checks, and deciding if dispatching using CallOnMainThread() is required.

Returns: true if the current thread is the main pepper thread, otherwise false.

void pp::Core::ReleaseResource ( PP_Resource resource )

inline

ReleaseResource() decrements the reference count for the provided resource. The resource will be deallocated if the reference count reaches zero.

Parameters

[in] resource A PP_Resource corresponding to a resource.
