# `GSFont.kerningContext`

*Instance Property*

Contextual kerning data.

## Declaration

```swift
var kerningContext: MGOrderedDictionary<NSString, MGOrderedDictionary<AnyObject, AnyObject>> { get set }
```

```objc
@property (nonatomic, strong) MGOrderedDictionary<NSString *,MGOrderedDictionary *> * kerningContext;
```

```python
kerningContext() -> MGOrderedDictionary<NSString *,MGOrderedDictionary *>
setKerningContext_(kerningContext: MGOrderedDictionary<NSString *,MGOrderedDictionary *>)
```

## Discussion

The outer dictionary is keyed by context key. Each context dictionary maps master identifiers to kerning values.
