构造及析构函数说明

TerrainBakedMaskCache() [1/3]

eve::procgen::TerrainBakedMaskCache::TerrainBakedMaskCache

(

)

Terrain baked mask cache.

在文件 TerrainBakedMaskCache.cpp 第 31 行定义.

~TerrainBakedMaskCache()

eve::procgen::TerrainBakedMaskCache::~TerrainBakedMaskCache ( )

default

Terrain baked mask cache.

TerrainBakedMaskCache() [2/3]

eve::procgen::TerrainBakedMaskCache::TerrainBakedMaskCache ( TerrainBakedMaskCache &&  )

defaultnoexcept

成员函数说明

clear()

void eve::procgen::TerrainBakedMaskCache::clear

(

)

Remove all entries.

在文件 TerrainBakedMaskCache.cpp 第 76 行定义.

copyMask()

Result< int > eve::procgen::TerrainBakedMaskCache::copyMask	(	const std::string &	terrainId,
		const std::string &	maskGuid,
		Heightmap &	output
	)		const

Copy one fresh entry into any positive output resolution using Clamp/Bilinear sampling.

返回

Changed output samples, or NotFound for missing/dirty data; failure never modifies output.

异常

std::bad_alloc

Output remains unchanged. @thread Synchronous owner-thread mutation; output is exclusively borrowed and no references escape.

引用了 eve::procgen::raster_detail::invalid(), output, eve::procgen::raster_detail::publish(), eve::procgen::raster_detail::textureSample(), eve::procgen::raster_detail::validRaster(), x , 以及 z.

erase()

Result< int > eve::procgen::TerrainBakedMaskCache::erase	(	const std::string &	terrainId,
		const std::string &	maskGuid
	)

Remove one exact entry.

在文件 TerrainBakedMaskCache.cpp 第 65 行定义.

引用了 eve::procgen::raster_detail::invalid() , 以及 eve::Result< T >::success().

getEntryCount()

int eve::procgen::TerrainBakedMaskCache::getEntryCount ( ) const

noexcept

Return the number of retained entries, including dirty entries.

markDirty()

Result< int > eve::procgen::TerrainBakedMaskCache::markDirty

(

const std::string &

maskGuid

)

Mark every matching GUID entry stale; stale reads fail until a provider stores a replacement.

在文件 TerrainBakedMaskCache.cpp 第 54 行定义.

引用了 eve::procgen::raster_detail::invalid() , 以及 eve::Result< T >::success().

operator=() [1/2]

TerrainBakedMaskCache & eve::procgen::TerrainBakedMaskCache::operator= ( const TerrainBakedMaskCache &  )

delete

operator=() [2/2]

TerrainBakedMaskCache & eve::procgen::TerrainBakedMaskCache::operator= ( TerrainBakedMaskCache &&  )

defaultnoexcept

Operator =.

store()

Result< int > eve::procgen::TerrainBakedMaskCache::store	(	const std::string &	terrainId,
		const std::string &	maskGuid,
		const Heightmap &	raster
	)

Copy or atomically replace one finite baked raster and mark it fresh.
