expose_live_indexed()

template<typename T >

bool MayaFlux::expose_live_indexed ( std::string_view  prefix, const std::shared_ptr< T > &  obj  )

noexcept

Exposes obj under the first free key of the form "prefix_N".

N starts at 0 and advances past keys already in the arena, so every call site sharing a prefix, such as the overloads of one Creator factory, draws from one sequence and none of them collide.

Template Parameters

T	Type of the object.

Parameters

prefix	Key prefix.
obj	shared_ptr to the existing object.

Returns

true on success, false if the directory is full.
