ICriteria
in

Criteria pattern interface for entity filtering and selection.

The ICriteria interface defines the contract for implementing the Criteria pattern, which provides a flexible way to define and combine filtering conditions for collections of entities. This pattern enables dynamic query construction and complex filtering logic through composable criteria objects.

Key benefits of the Criteria pattern:

  • Encapsulates filtering logic in reusable objects
  • Supports dynamic query construction at runtime
  • Enables complex criteria composition (AND, OR, NOT operations)
  • Provides type-safe filtering without string-based queries
  • Allows for criteria caching and optimization
  • Supports both in-memory and database filtering strategies

Common criteria implementations:

  • KeyValue: Filter by exact key-value matches
  • AndCriteria: Logical AND combination of multiple criteria
  • OrCriteria: Logical OR combination of multiple criteria
  • NotCriteria: Logical negation of another criteria
  • Range criteria: Filter by numeric or date ranges
  • Pattern criteria: Filter by regular expression patterns

example 
// Simple criteria implementation
class ActiveUserCriteria implements ICriteria
{
    public function meetCriteria(array $entities): array
    {
        return array_filter($entities, function($user) {
            return $user->isActive();
        });
    }
}

// Complex criteria composition
$activeCriteria = new KeyValue('status', 'active');
$adminCriteria = new KeyValue('role', 'admin');
$activeAdmins = new AndCriteria($activeCriteria, $adminCriteria);

$filteredUsers = $activeAdmins->meetCriteria($allUsers);
