Member Function Documentation

template<typename T >
static impala::PrettyPrinter::ENABLE_IF_ARITHMETIC ( T  ,
std::string   
)
static

Prints the 'value' in a human friendly format depending on the data type. i.e. for bytes: 3145728 -> 3MB If verbose is true, this also prints the raw value (before unit conversion) for types where this is applicable.

template<typename T >

double   
) const
static
template<typename T >
static impala::PrettyPrinter::ENABLE_IF_INTEGRAL ( T  ,
int64_t   
) const
static

Utility to perform integer modulo if T is integral, otherwise to use fmod().
