SkFlattenable Class Reference

SkFlattenable is the base class for objects that need to be flattened into a data stream for either transport or as part of the key to the font cache. More...

Member Function Documentation

Deserialize()

static sk_sp<SkFlattenable> SkFlattenable::Deserialize ( Type  , const void *  data, size_t  length, const SkDeserialProcs *  procs = nullptr  )

static

FactoryToName()

static const char* SkFlattenable::FactoryToName ( Factory  )

static

flatten()

virtual void SkFlattenable::flatten ( SkWriteBuffer &  ) const

inlinevirtual

Override this if your subclass needs to record data that it will need to recreate itself from its CreateProc (returned by getFactory()).

DEPRECATED public : will move to protected ... use serialize() instead

Reimplemented in SkLayerDrawLooper.

getFactory()

virtual Factory SkFlattenable::getFactory ( ) const

pure virtual

Implement this to return a factory function pointer that can be called to recreate your class given a buffer (previously written to by your override of flatten().

Implemented in SkDrawable.

getFlattenableType()

virtual Type SkFlattenable::getFlattenableType ( ) const

pure virtual

Implemented in SkDrawLooper, and SkDrawable.

getTypeName()

virtual const char* SkFlattenable::getTypeName ( ) const

pure virtual

Returns the name of the object's class.

Implemented in SkDrawable.

NameToFactory()

static Factory SkFlattenable::NameToFactory ( const char  name[] )

static

ref()

void SkRefCntBase::ref ( ) const

inlineinherited

Increment the reference count.

Must be balanced by a call to unref().

Register()

static void SkFlattenable::Register ( const char  name[], Factory    )

static

serialize() [1/2]

sk_sp<SkData> SkFlattenable::serialize

(

const SkSerialProcs *

= nullptr

)

const

serialize() [2/2]

size_t SkFlattenable::serialize	(	void *	memory,
		size_t	memory_size,
		const SkSerialProcs *	= nullptr
	)		const

unique()

bool SkRefCntBase::unique ( ) const

inlineinherited

May return true if the caller is the only owner.

Ensures that all previous owner's actions are complete.

unref()

void SkRefCntBase::unref ( ) const

inlineinherited

Decrement the reference count.

If the reference count is 1 before the decrement, then delete the object. Note that if this is the case, then the object needs to have been allocated via new, and not on the stack.
