Detailed Description

Integer domain classes for sparse data structures.

This file provides domain classes representing sets of values, primarily used as index domains for sparse matrices and vectors.

Features

• Hash-based set for O(1) membership testing
• Sorted key iteration
• Range-based domain construction

Usage Example

// Create domain [0, 9]
IntRange domain(0, 9);
 
// Create domain {0, 1, ..., n-1}
IntRange indices(100);
 
// Create domain with step: {0, 2, 4, 6, 8, 10}
IntRange even(0, 10, 2);
