详细描述

Owned scalar animation curves indexed by stable source and channel names.

Contains no skeleton, clip, filesystem or script references. Mutations are owner-thread only, with no callbacks or reentrancy. Concurrent const sampling is allowed while the owner guarantees no load/destruction. Samples use injected time.

构造及析构函数说明

AnimCurveLibrary() [1/2]

eve::animation::AnimCurveLibrary::AnimCurveLibrary

(

)

Construct an empty library with independent lifetime.

在文件 AnimCurveLibrary.cpp 第 62 行定义.

~AnimCurveLibrary()

eve::animation::AnimCurveLibrary::~AnimCurveLibrary ( )

default

Destroy owned curve data without accessing external objects.

AnimCurveLibrary() [2/2]

eve::animation::AnimCurveLibrary::AnimCurveLibrary ( const AnimCurveLibrary &  )

delete

成员函数说明

contains()

bool eve::animation::AnimCurveLibrary::contains

(

std::string_view

source

)

const

Query whether a source record exists, including records without channels.

在文件 AnimCurveLibrary.cpp 第 108 行定义.

引用了 source.

被这些函数引用 eve::animation::exposeAnimCurveLibraryBindings().

load()

eve::Result< void > eve::animation::AnimCurveLibrary::load

(

std::span< const std::byte >

bytes

)

Atomically replace data from little-endian eve.animation-curves/1 bytes.

参数

bytes

Borrowed for this synchronous call only; decoded values are owned.

返回

Applied, or InvalidArgument preserving all previous data. Rejects unknown versions, trailing bytes, invalid UTF-8, duplicates, nonfinite/unsorted keys and resource limits. Empty channels are absent; endpoints must span clip duration.

在文件 AnimCurveLibrary.cpp 第 64 行定义.

引用了 eve::Applied, bytes, clip, count, error, eve::Result< T >::failure(), key, name, source, eve::Status::success() , 以及 eve::Result< T >::success().

被这些函数引用 eve::animation::exposeAnimCurveLibraryBindings().

operator=()

AnimCurveLibrary & eve::animation::AnimCurveLibrary::operator= ( const AnimCurveLibrary &  )

delete

sample()

eve::Result< std::optional< float > > eve::animation::AnimCurveLibrary::sample	(	std::string_view	source,
		std::string_view	channel,
		double	seconds,
		bool	loop
	)		const

Evaluate one scalar channel with linear interpolation.

参数

source	Borrowed stable source name; never retained.
channel	Borrowed channel name; never retained.
seconds	Finite simulation time; looping wraps negative time too, otherwise clamps.
loop	Whether to wrap at the source duration. No external clip state is read.

返回

Owning optional value (empty for an absent channel), NotFound for an unknown source, or InvalidArgument for nonfinite time. No state is mutated; repeat calls are deterministic within float rounding tolerance.

在文件 AnimCurveLibrary.cpp 第 110 行定义.

引用了 a, b, clip, curve, end, eve::Diagnostic::error(), eve::Result< T >::failure(), found, key, loop, eve::NotFound, source, eve::Result< T >::success() , 以及 time.

被这些函数引用 eve::animation::exposeAnimCurveLibraryBindings().

size()

std::size_t eve::animation::AnimCurveLibrary::size ( ) const

noexcept

Return the number of source records currently owned.

在文件 AnimCurveLibrary.cpp 第 109 行定义.

被这些函数引用 eve::animation::exposeAnimCurveLibraryBindings().
