Detailed Description

template<typename T, size_t Capacity, bool Exp2 = true>
class cds::opt::v::uninitialized_static_buffer< T, Capacity, Exp2 >

Static uninitialized buffer.

One of available type for opt::buffer option.

This buffer maintains static array of uninitialized elements. You should manually construct each element when needed. No dynamic memory allocation performed.

Template parameters:

T - item type the buffer stores
Capacity - the capacity of buffer. The value must be power of two if Exp2 is true
Exp2 - a boolean flag. If it is true the buffer capacity must be power of two. Otherwise it can be any positive number. Usually, it is required that the buffer has size of a power of two.

Constructor & Destructor Documentation

◆ uninitialized_static_buffer()

template<typename T , size_t Capacity, bool Exp2 = true>

cds::opt::v::uninitialized_static_buffer< T, Capacity, Exp2 >::uninitialized_static_buffer ( size_t nCapacity )

inlinenoexcept

Construct buffer of given capacity.

This ctor ignores nCapacity argument. The capacity of static buffer is defined by template argument Capacity

Member Function Documentation

◆ mod()

template<typename T , size_t Capacity, bool Exp2 = true>

size_t cds::opt::v::uninitialized_static_buffer< T, Capacity, Exp2 >::mod ( size_t idx )

inline

Returns idx % capacity()

If the buffer size is a power of two, binary arithmethics is used instead of modulo arithmetics
