Beautiful binary tree drawing

This piece of code helps you to draw the binary tree beautifully.

DrawFactory provides the drawer, which displays your tree in following formats :

Tree Format

By set Mode to DrawMode.TREE

• Displaying the binary tree in tree-format. The logic would take into account the length of your value in the tree node.

  Besides, you can also modify the distance between 2 stages as well as the minimal indent-distance between 2 tree nodes.

• Here is the demo

Directory Format

By set Mode to DrawMode.DIRECTORY

• Displaying the binary tree in directory-format.

  You can modyfy the distance between 2 stages as well as the horizontal indent-distance

• Here is the demo

Hierarchy Format

By set Mode to DrawMode.HIERARCHY

• Displaying the binary tree in hierarchy-format

  You can modify minimal indent-distance between tree nodes.

• Here is the demo

Parsing tree from file

In addition: If you are tired of constructing the tree node-instances by hand. You can provide your tree as following rules to get the tree

• Line format:   {position} , {node's value} with position :=

  • t (root)
  • r (right)
  • l (left)

  You can look into this Example

• Just read text file (.txt-format)

• One node information per line
