compareCustom(java.nio.ByteBuffer o1,

Implement IFF ComparisonType is CUSTOM
Compares the ByteBuffer representation of two instances of this class,
for types where this cannot be done by simple in-order comparison of the
unsigned bytes
Standard Java compare semantics

freezeNestedMulticellTypes()
Returns an AbstractType instance that is equivalent to this one, but with all nested UDTs and collections
explicitly frozen.
