## flytekit.models.core.condition.BooleanExpression

### Parameters

```python
class BooleanExpression(
    conjunction,
    comparison,
)
```
Defines a boolean expression tree. It can be a simple or a conjunction expression.
Multiple expressions can be combined using a conjunction or a disjunction to result in a final boolean result.

| Parameter | Type | Description |
|-|-|-|
| `conjunction` |  | |
| `comparison` |  | |

### Properties

| Property | Type | Description |
|-|-|-|
| `comparison` | `None` | Comparison expression or None if not set. |
| `conjunction` | `None` | Conjunction expression or None if not set. |
| `is_empty` | `None` |  |
