Detailed Description

Interface for intercepting pre-composed layer creation.

Embedders can register interceptors with animation builders, to substitute target layers with arbitrary/externally-controlled content (see ExternalLayer above).

Member Function Documentation

onLoadPrecomp()

virtual sk_sp<ExternalLayer> skottie::PrecompInterceptor::onLoadPrecomp ( const char  id[], const char  name[], const SkSize &  size  )

pure virtual

Invoked at animation build time, for each precomp layer.

Parameters

id	The target composition ID (usually assigned automatically by BM: comp_0, ...)
name	The name of the precomp layer (by default it matches the target comp name, but can be changed in AE)
size	Lottie-specified precomp layer size

Returns

An ExternalLayer implementation (to be used instead of the actual Lottie file content), or nullptr (to use the Lottie file content).

ref()

void SkRefCntBase::ref ( ) const

inlineinherited

Increment the reference count.

Must be balanced by a call to unref().

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.
