详细描述

Dense, sorted multi-map used to wake O(watchers) rules on a fact change.

Rule ids are stored as dense integers assigned by RuleEngine. String ids are resolved by the engine; this index never owns string storage.

在文件 WatchIndex.h 第 23 行定义.

成员函数说明

addRule()

void eve::emergence::WatchIndex::addRule	(	std::uint32_t	ruleIndex,
		const std::vector< std::string > &	keys
	)

Index one rule under each of its watch keys.

参数

ruleIndex	Dense rule slot owned by the catalogue.
keys	Canonical fact keys; duplicates are ignored.

在文件 WatchIndex.cpp 第 9 行定义.

引用了 key.

clear()

void eve::emergence::WatchIndex::clear

(

)

Remove every subscription.

在文件 WatchIndex.cpp 第 7 行定义.

collect()

std::size_t eve::emergence::WatchIndex::collect	(	std::string_view	key,
		std::vector< std::uint32_t > &	out
	)		const

Collect unique rule indexes that watch a key into out.

参数

key	Canonical fact key.
out	Appended dense indexes; caller clears or uses a set for uniqueness.

返回

Number of subscribers appended (including duplicates across calls).

在文件 WatchIndex.cpp 第 18 行定义.

引用了 key.

keyCount()

std::size_t eve::emergence::WatchIndex::keyCount ( ) const

inlinenoexcept

Number of distinct keys with at least one subscriber.

在文件 WatchIndex.h 第 44 行定义.
