Member Function Documentation

int64_t impala::ParseUtil::ParseMemSpec ( const std::string &  mem_spec_str, bool *  is_percent, int64_t  relative_reference  )

static

Parses mem_spec_str and returns the memory size in bytes. Sets *is_percent to indicate whether the given spec is in percent. Accepted formats: '<int>[bB]?' -> bytes (default if no unit given) '<float>[mM(bB)]' -> megabytes '<float>[gG(bB)]' -> in gigabytes '<int>' -> in percent of relative_reference 'relative_reference' -> value used to compute the percentage value, typically MemInfo::physical_mem() Requires MemInfo to be initialized for the '' spec to work. Returns 0 if mem_spec_str is empty or '-1'. Returns -1 if parsing failed.
