## Code Conventions

### Class Structure

- **Utility classes**: `abstract` class + `protected` constructor
- **Constants classes**: Same pattern

### Argument Validation

Use `AssertionUtil` at method entry:
- `AssertionUtil.assertArgumentNotNull("argName", value)`
- `AssertionUtil.assertArgumentNotEmpty("argName", value)`

### Exception Handling

  public boolean isEmpty() {
    return delegateCollection().isEmpty();
  }

  @Override
  boolean isPartialView() {
    return delegateCollection().isPartialView();
  }

  /** Serialized form that leads to the same performance as the original list. */
