DataTreeModification (yangtools-docs 8.0.0 API)

All Superinterfaces:

DataTreeSnapshot, EffectiveModelContextProvider

All Known Subinterfaces:

CursorAwareDataTreeModification
```
public interface DataTreeModification
extends DataTreeSnapshot
```
Class encapsulation of set of modifications to a base tree. This tree is backed by a read-only snapshot and tracks modifications on top of that. The modification has the ability to rebase itself to a new snapshot.

- Method Detail
  - delete
```
void delete(YangInstanceIdentifier path)
```
    Delete the node at specified path.
    
    Parameters:
    
    path - Node path
  - merge
```
void merge(YangInstanceIdentifier path,
           NormalizedNode data)
```
    Merge the specified data with the currently-present data at specified path.
    
    Parameters:
    
    path - Node path
    
    data - Data to be merged
  - write
```
void write(YangInstanceIdentifier path,
           NormalizedNode data)
```
    Replace the data at specified path with supplied data.
    
    Parameters:
    
    path - Node path
    
    data - New node data
  - ready
```
void ready()
```
    Finish creation of a modification, making it ready for application to the data tree. Any calls to this object's methods except applyToCursor(DataTreeModificationCursor) will result in undefined behavior, possibly with an IllegalStateException being thrown.
  - applyToCursor
```
void applyToCursor(@NonNull DataTreeModificationCursor cursor)
```
    Apply the contents of this modification to a cursor. This can be used to replicate this modification onto another one. The cursor's position must match the root of this modification, otherwise performing this operation will result in undefined behavior.
    
    Parameters:
    
    cursor - cursor to which this modification
