Macro Definition Documentation

SKGPU_DECLARE_STATIC_UNIQUE_KEY

#define SKGPU_DECLARE_STATIC_UNIQUE_KEY

(

name

)

static SkOnce name##_once

It is common to need a frequently reused UniqueKey where the only requirement is that the key is unique. These macros create such a key in a thread safe manner so the key can be truly global and only constructed once. Place outside of function/class definitions.

SKGPU_DEFINE_STATIC_UNIQUE_KEY

#define SKGPU_DEFINE_STATIC_UNIQUE_KEY

(

Value:

    static SkAlignedSTStorage<1, skgpu::UniqueKey> name##_storage;          \
    name##_once(skgpu::skgpu_init_static_unique_key_once, &name##_storage); \
    static const skgpu::UniqueKey& name =                                   \
        *reinterpret_cast<skgpu::UniqueKey*>(name##_storage.get())

Place inside function where the key is used.
