Detailed Description

template<class Impl>
class net_instaweb::VarTemplate< Impl >

Helper class to create Variable interface implementations given a helper implementation class Impl. Note that the same Impl class can be used for UpDownTemplate, but Variable will not provide a Set method, and will DCHECK-fail on negative increments.

class Impl must define methods: Impl(StringPiece name, Statistics* stats); int64 Get(); StringPiece GetName(); int64 AddHelper(int64 delta); void Clear(); See ../util/simple_stats.h, class SimpleStatsVariable, for an example of an Impl class.
