ramkrishna.s.vasudevan commented on PHOENIX-777:
------------------------------------------------
I checked the code, though we can allow the Integer ARRAY to use the Integer
(the object array[]) to represent the array elements the PInteger data type as
such does not allow the element to be a null.
{code}
if (object == null) {
throw newIllegalDataException(this + " may not be null");
}
{code}
> Support null value for fixed length ARRAY

> A null value for a fixed length array can be handled with a bitset tacked on
> the end of the array. If an element is set to null, then the bit at that
> index is set. Trailing nulls are not stored and an attempt to access an array
> past the current size returns null.
> Current behavior,
> PBinaryArray - Throws an exception when a null is inserted.
> PBooleanArray - null is considered as false when a null is inserted.
> PCharArray - Throws an exception when a null is inserted.
> PDateArray - Throws an exception when a null is inserted.
> PDoubleArray - null is considered as 0.0 when a null is inserted.
> PFloatArray - null is considered as 0.0 when a null is inserted.
> PIntegerArray - null is considered as 0 when a null is inserted.
> PLongArray - null is considered as 0 when a null is inserted.
> PSmallIntArray - null is considered as 0 when a null is inserted.
> PTimeArray - Throws an exception when a null is inserted.
> PTimeStampArray - Throws an exception when a null is inserted.
> PTinyIntArray - null is considered as 0 when a null is inserted.
