## API
|
||
|
|
|
||
|
|
### cleanYamlObject(input, [filterFn])
|
||
|
|
|
||
|
|
Returns a deep copy of `input` that is suitable for serialization.
|
||
|
|
|
||
|
|
#### input
|
||
|
|
|
||
|
|
Type: `*`
|
||
|
|
|
||
|
|
Any object.
|
||
|
|
|
||
|
|
#### filterFn
|
||
|
|
|
||
|
|
Type: `callback(propertyName, isRoot, source, target)`
|
||
|
|
|
||
|
|
Optional filter callback. Returning `true` will cause the property to be copied. Otherwise it will be skipped
|
||
|
|
|
||
|
|
- `propertyName`: The property being copied.
|
||
|
|
- `isRoot`: `true` only if `source` is the top level object passed to `copyYamlObject`
|
||
|
|
- `source`: The source from which `source[propertyName]` will be copied.
|
||
|
|
- `target`: The target object.
