      • isUndefined

        public boolean isUndefined​(int pos)
        Returns true if the value at the given position is undefined. A value can be undefined in 4 cases:
        1. It is a double and its value is NaN (Not a Number).
        2. It is an integer or boolean with no valid value (arithmetic or out of bounds exception).
        3. It is an interval with at least one undefined bound.
        4. It is the result of any ill-defined operation (at with out of bounds index or operations on undefined values for instance).
        Parameters:
        pos - Position of the value to query.
        Returns:
        True if the value at the given position is undefined.
      • isUndefined

        public boolean isUndefined()
        Returns true if the array is undefined. An array can be undefined if it is the result of any ill-defined operation (at with out of bounds index or operations on undefined values for instance).
        Returns:
        True if the array is undefined.
      • getIntValue

        public long getIntValue​(int pos)

      • copyTo

        public void copyTo​(long[] values)

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

        The length of the array given in parameters can be different from the number of elements in this array. 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 this array, instead of the roughly equivalent, but less performant, following code:

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

        public void copyTo​(double[] values)

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

        The length of the array given in parameters can be different from the number of elements in this array. 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 this array, instead of the roughly equivalent, but less performant, following code:

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