Method Detail

hasValue

boolean hasValue()

 Scalar values are represented using floating point. To reduce
 the chance of unpredictable floating point behavior due to
 roundoff error, Mesos only supports three decimal digits of
 precision for scalar resource values. That is, floating point
 values are converted to a fixed point format that supports
 three decimal digits of precision, and then converted back to
 floating point on output. Any additional precision in scalar
 resource values is discarded (via rounding).
 

required double value = 1;
