Public Member Functions
	indexed_collector (std::size_t n)
	Construct an indexed_collector with n slots.
void	set (std::size_t i, const T &v)
	Set the value at index i to v. This function can be called concurrently as long as callers pass distinct i.
std::vector< T >	compact () const
	Get a compacted vector of all filled slots. This function is not thread-safe and should only be called after all writes are complete.

Detailed Description

template<typename T>
class wmtk::threading::indexed_collector< T >

A collector that is not thread-safe for concurrent writes to the same index, but is thread-safe for concurrent writes to distinct indices. This is useful when each thread knows a unique slot for its result, allowing for lock-free writes.

Constructor & Destructor Documentation

indexed_collector()

template<typename T >

wmtk::threading::indexed_collector< T >::indexed_collector ( std::size_t  n )

inlineexplicit

Construct an indexed_collector with n slots.

Parameters

n	The number of slots to allocate.

Member Function Documentation

compact()

template<typename T >

std::vector< T > wmtk::threading::indexed_collector< T >::compact ( ) const

inline

Get a compacted vector of all filled slots. This function is not thread-safe and should only be called after all writes are complete.

Returns

A vector containing all values that have been set, in the order of their indices.

set()

template<typename T >

void wmtk::threading::indexed_collector< T >::set ( std::size_t  i, const T &  v  )

inline

Set the value at index i to v. This function can be called concurrently as long as callers pass distinct i.

Parameters

i	The index to set.
v	The value to set.
