TreeNode (tree-printer 2.0.0 API)

All Known Implementing Classes:

AbstractTreeNodeDecorator, BorderTreeNodeDecorator, DefaultFsTreeNodeDecorator, FsTreeNode, JustifyTreeNodeDecorator, PadTreeNodeDecorator, PlaceholderNode, ShadowTreeNodeDecorator, SimpleTreeNode, TrackingTreeNodeDecorator
```
public interface TreeNode
```
Main interface for trees and tree nodes. Any tree is given by its root node. Nodes provide their content as a string (via content()), and list their children (via children()). The other methods provide metadata, each has a default implementation.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`java.util.List<TreeNode>`	`children()`	Gets the list of child nodes of this node.
`java.lang.String`	`content()`	Gets the content of this node.
`default Insets`	`insets()`	Gets the content insets.
`default boolean`	`isDecorable()`	Checks if this node can be decorated.
`default boolean`	`isPlaceholder()`	Checks if this node is a placeholder.
`default TreeNode`	`originalNode()`	Gets the original node object.

- Method Detail
  - content
```
java.lang.String content()
```
    Gets the content of this node.
  - children
```
java.util.List<TreeNode> children()
```
    Gets the list of child nodes of this node.
  - originalNode
```
default TreeNode originalNode()
```
    Gets the original node object. By default, returns with this. Decorators should return with the most inner decorated node.
  - insets
```
default Insets insets()
```
    Gets the content insets. Returns with the sizes of the visual decoration around the main content. By default, this is fully zero. Visually extending decorators (border, shadow etc.) should extend the insets with the sizes of the visual extension.
  - isDecorable
```
default boolean isDecorable()
```
    Checks if this node can be decorated. By default, decorators should keep non-decorable nodes untouched.
  - isPlaceholder
```
default boolean isPlaceholder()
```
    Checks if this node is a placeholder. By default, generic TreePrinter implementations hide placeholder nodes. Some types of implementation (e. g. n-ary trees) should take these into account anyway.
