Member Function Documentation

asUint8()

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

inline

Returns prefix length as uint8_t value.

asUnsigned()

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

inline

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.
