Member Function Documentation

◆ asUint8()

uint8_t isc::dhcp::PrefixLen::asUint8 ( ) const

Returns prefix length as uint8_t value.

Definition at line 295 of file option_data_types.h.

Referenced by isc::dhcp::OptionDataTypeUtil::writePrefix().

◆ asUnsigned()

unsigned int isc::dhcp::PrefixLen::asUnsigned ( ) const

Returns prefix length as unsigned int.

This is useful to convert the value to a numeric type which can be logged directly. See PSIDLen::asUnsigned for the use cases of this accessor.
