getDomain()

long com.google.ortools.sat.IntegerVariableProtoOrBuilder.getDomain

(

int

index

)

The variable domain given as a sorted list of n disjoint intervals
[min, max] and encoded as [min_0, max_0,  ..., min_{n-1}, max_{n-1}].

The most common example being just [min, max].
If min == max, then this is a constant variable.

We have:
 - domain_size() is always even.
 - min == domain.front();
 - max == domain.back();
 - for all i < n   :      min_i <= max_i
 - for all i < n-1 :  max_i + 1 < min_{i+1}.

Note that we check at validation that a variable domain is small enough so
that we don't run into integer overflow in our algorithms. Because of that,
you cannot just have "unbounded" variable like [0, kint64max] and should
try to specify tighter domains.

repeated int64 domain = 2;

Parameters

index

The index of the element to return.

Returns

The domain at the given index.

Implemented in com.google.ortools.sat.IntegerVariableProto, and com.google.ortools.sat.IntegerVariableProto.Builder.

Returns

A list containing the domain.
