# LayoutAnalyzer

The `LayoutAnalyzer` class provides a high-performance layout analysis engine. It analyzes the spatial distribution of quadrilaterals to detect and map structural patterns (Lines or Matrix), with logical grid position mapping and gap-filling inference.

## Definition

*Module:* utility

```python
class LayoutAnalyzer:
```

## Methods

| Method | Description |
|--------|-------------|
| [`analyze`](#analyze) | Performs layout analysis on an array of quadrilaterals and returns a result set. |

## analyze

Performs layout analysis and returns a result set.

```python
@staticmethod
def analyze(inputQuads: List[Quadrilateral], param: LayoutAnalysisParameter = None) -> LayoutAnalysisResult:
```

**Parameters**

`inputQuads` Array of input quadrilaterals.

`param` Optional parameters to constrain the analysis.

**Return Value**

Returns a `LayoutAnalysisResult` object, or `None` on failure.
