public abstract class T1DictDelta
extends T1DictKey

Type 1 dict delta.

The length of array or delta types is determined by counting the operands preceding the operator. The second and subsequent numbers in a delta are encoded as the difference between successive values. For example, an array a0, a1, ..., an would be encoded as: a0 (a1-a0) (a2-a1) ..., (an-a(n-1)).

For calculation, you must use a0 (a1+a0) (a2+a1) ..., (an+a(n-1))
