Detailed Description

template<typename EnumType, size_t NumEnums>
class net_instaweb::EnumSet< EnumType, NumEnums >

Represents a set of values – implemented via a bitset.

Member Function Documentation

template<typename EnumType, size_t NumEnums>

void net_instaweb::EnumSet< EnumType, NumEnums >::insert ( EnumType  value )

inline

Inserts a value; no return value.

Todo:

TODO(jmarantz): change call-sites to Insert and remove this one.

template<typename EnumType, size_t NumEnums>

bool net_instaweb::EnumSet< EnumType, NumEnums >::Merge ( const EnumSet< EnumType, NumEnums > &  src )

inline

Merges src into this, returning whether this resulted in a change.

We save the current version of the set in order to see whether the merge resulted in a change. Note that copying and comparing the bits is very cheap; probably cheaper than calling count().

template<typename EnumType, size_t NumEnums>

bool net_instaweb::EnumSet< EnumType, NumEnums >::MergeInverted ( const EnumSet< EnumType, NumEnums > &  src )

inline

Merges the entries not set in src into this, returning whether this resulted in a change.
