using comms::option::def::BitmaskReservedBits = typedef ContentsValidator<details::BitmaskReservedBitsValidator<TMask, TValue> >

Alias to ContentsValidator, it defines validator class that checks that reserved bits of the field have expected values.

It is usually used with comms::field::BitmaskValue field to specify values of the unused/reserved bits. The custom validator will return true if

(field.value() & TMask) == TValue

Template Parameters

TMask	Mask that specifies reserved bits.
TValue	Expected value of the reserved bits. Defaults to 0.

◆ DefaultBigUnsignedNumValue

template<std::uintmax_t TVal>

using comms::option::def::DefaultBigUnsignedNumValue = typedef DefaultValueInitialiser< details::DefaultNumValueInitialiser<std::uintmax_t, TVal> >

Alias to DefaultValueInitialiser, it defines initialiser class that assigns big unsigned numeric value provided as the template argument to this option.

If the required numeric value is small enough to fit into std::intmax_t type, it is recommended to use DefaultNumValue option class instead.

Template Parameters

TVal	Numeric value is to be assigned to the field in default constructor.

See also: DefaultBigUnsignedNumValue

◆ DefaultNumValue

template<std::intmax_t TVal>

using comms::option::def::DefaultNumValue = typedef DefaultValueInitialiser< details::DefaultNumValueInitialiser<std::intmax_t, TVal> >

Alias to DefaultValueInitialiser, it defines initialiser class that assigns numeric value provided as the template argument to this option.

If the required numeric value is too big (doesn't fit into std::intmax_t type), please use DefaultBigUnsignedNumValue option class instead.

Template Parameters

TVal	Numeric value is to be assigned to the field in default constructor.

See also: DefaultBigUnsignedNumValue

◆ DefaultOptionalMode

template<comms::field::OptionalMode TVal>

using comms::option::def::DefaultOptionalMode = typedef DefaultValueInitialiser<details::DefaultOptModeInitialiser<TVal> >
