opencv_core.FileNode (JavaCPP Presets for OpenCV 2.4.9-0.8 API)

java.lang.Object
- org.bytedeco.javacpp.Pointer
- - org.bytedeco.javacpp.opencv_core.FileNode

Enclosing class:

opencv_core
```
public static class opencv_core.FileNode
extends Pointer
```
File Storage Node class The node is used to store each and every element of the file storage opened for reading - from the primitive objects, such as numbers and text strings, to the complex nodes: sequences, mappings and the registered objects. Note that file nodes are only used for navigating file storages opened for reading. When a file storage is opened for writing, no data is stored in memory after it is written.
