Detailed Description

Framework to define template options.

There are two kind of options:

• type-option - option that determines a data type. The template argument Type of the option is a type.
• value-option - option that determines a value. The template argument Value of the option is a value.

Enumeration Type Documentation

special_alignment

enum cds::opt::special_alignment

Special alignment constants for cds::opt::alignment option.

Enumerator
no_special_alignment	no special alignment
cache_line_alignment	use cache line size defined in cds/user_setup/cache_line.h

special_padding

enum cds::opt::special_padding

Special padding constants for cds::opt::padding option.

Enumerator
no_special_padding	no special padding
cache_line_padding	use cache line size defined in cds/user_setup/cache_line.h
padding_tiny_data_only	Apply padding only for tiny data when data size is less than required padding. The flag means that if your data size is less than the cacheline size, the padding is applyed. Otherwise no padding will be applyed. This flag is applyed for padding value: cds::opt::padding< cds::opt::cache_line_padding | cds::opt::padding_tiny_data_only >; cds::opt::padding< 256 | cds::opt::padding_tiny_data_only >;
