Detailed Description

A FreeTypeFace wraps an FT_Face object of the FreeType library together with a mutex in a reference counted object.

The threading model for the FreeType appears to be:

Create an FT_Library object
When creating or releasing FT_Face objects, lock a mutex around the FT_Library when doing so
If an FT_Face is accessed from multiple threads, the FT_Face (but not the FT_Library) needs to be mutex locked

Constructor & Destructor Documentation

fastuidraw::FreeTypeFace::FreeTypeFace	(	FT_Face	pFace,
		const reference_counted_ptr< FreeTypeLib > &	pLib
	)

Ctor.

Parameters

pFace	the underlying FT_Face; the created FreeTypeFace takes ownership of pFace and pFace will be deleted when the created FreeTypeFace is deleted.
pLib	the FreeTypeLib that was used to create pFace

FT_Face fastuidraw::FreeTypeFace::face ( void )

Returns the FT_Face object about which this object wraps.

const reference_counted_ptr<FreeTypeLib>& fastuidraw::FreeTypeFace::lib ( void ) const

Returns the FreeTypeLib that was used to create the FT_Face face().

void fastuidraw::FreeTypeFace::lock ( void )

Aquire the lock of the mutex used to access/use the FT_Face return by face() safely across multiple threads.

bool fastuidraw::FreeTypeFace::try_lock ( void )

Try to aquire the lock of the mutex. Return true on success.

void fastuidraw::FreeTypeFace::unlock ( void )

Release the lock of the mutex used to access/use the FT_Face return by face() safely across multiple threads.
