      • count

        public int count()
        Returns the number of values in the current argument values. Values are indexed from 0 to count() - 1.

        Number of values.

      • copyTo

        public void copyTo​(long[] values)

        Copy all the integer values of the argument values to the given array. Only the integer values are copied to their corresponding position in the array. Cells of the array that correspond to positions of non-integer values in the argument values remain unchanged.

        The length of the array can be different from the number of elements in the argument values. In that case, only the elements that fit in the array are copied.

        This method is recommended if you need to access all the values of the argument values, instead of the roughly equivalent, but less performant, following code:

         
 for(int i = 0; i < Math.min(values.length, argumentValues.count()); ++i) {
     if(!argumentValues.isInt(i)) continue;
     values[i] = argumentValues.getIntValue(i);
 }
        Parameters:
        values - array that will receive the integer values of the argument values.

      • copyTo

        public void copyTo​(double[] values)

        Copy all the double values of the argument values to the given array. Only the double values are copied to their corresponding position in the array. Cells of the array that correspond to positions of non-double values in the argument values remain unchanged.

        The length of the array can be different from the number of elements in the argument values. In that case, only the elements that fit in the array are copied.

        This method is recommended if you need to access all the values of the argument values, instead of the roughly equivalent, but less performant, following code:

         
 for(int i = 0; i < Math.min(values.length, argumentValues.count()); ++i) {
     if(!argumentValues.isDouble(i)) continue;
     values[i] = argumentValues.getDouble(i);
 }
        Parameters:
        values - array that will receive the double values of the argument values.
