函数说明

addListener()

template<class I >

void eve::cap::addListener	(	I *	impl,
		int	priority = 0
	)

Adds listener.

Add one of possibly many implementations. Lower priority runs first.

Adds listener raw.

在文件 Capability.h 第 151 行定义.

引用了 eve::cap::detail::addListenerRaw(), impl , 以及 priority.

forEach()

template<class I , class F >

void eve::cap::forEach

(

F &&

fn

)

Call fn for every implementation of I in priority order.

Dispatch uses a snapshot of the listener pointers taken before the first callback. Registrations and withdrawals made by a callback affect later dispatches, but not the dispatch already in progress. A withdrawn listener must therefore remain alive until the current dispatch returns.

For each.

在文件 Capability.h 第 186 行定义.

引用了 fn, impl, eve::cap::detail::listenerAtRaw(), eve::cap::detail::listenerCountRaw() , 以及 n.

forEachUntil()

template<class I , class F >

bool eve::cap::forEachUntil

(

F &&

fn

)

Call fn for each snapshotted implementation until one returns true.

Listener mutations have the same next-dispatch semantics as forEach().

返回

Whether any implementation returned true.

For each until.

在文件 Capability.h 第 205 行定义.

引用了 fn, impl, eve::cap::detail::listenerAtRaw(), eve::cap::detail::listenerCountRaw() , 以及 n.

listenerAt()

template<class I >

I * eve::cap::listenerAt

(

size_t

index

)

Listener at.

在文件 Capability.h 第 172 行定义.

引用了 index , 以及 eve::cap::detail::listenerAtRaw().

listenerCount()

template<class I >

size_t eve::cap::listenerCount

(

)

Listener count.

Listener count raw.

在文件 Capability.h 第 165 行定义.

引用了 eve::cap::detail::listenerCountRaw().

provide()

template<class I >

void eve::cap::provide

(

I *

impl

)

Provides .

Register the single implementation of I, replacing any previous one.

Provides raw.

在文件 Capability.h 第 80 行定义.

引用了 impl , 以及 eve::cap::detail::provideRaw().

query()

template<class I >

I * eve::cap::query

(

)

Queries .

The implementation of I, or nullptr when no module provides it.

在文件 Capability.h 第 88 行定义.

引用了 eve::cap::detail::queryRaw().

removeListener()

template<class I >

void eve::cap::removeListener

(

I *

impl

)

Removes listener.

Removes listener raw.

在文件 Capability.h 第 158 行定义.

引用了 impl , 以及 eve::cap::detail::removeListenerRaw().

revoke()

template<class I >

void eve::cap::revoke

(

I *

impl

)

Revoke.

Withdraw impl; a no-op when something else has since taken the slot.

Revoke raw.

在文件 Capability.h 第 143 行定义.

引用了 impl , 以及 eve::cap::detail::revokeRaw().
