Detailed Description

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.

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 SkPath2DPathEffect, SkLayerDrawLooper, SkLine2DPathEffect, SkPath1DPathEffect, SkDiscretePathEffect, Sk2DPathEffect, and SkCornerPathEffect.

◆ 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

◆ 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.
