Returns the alignment of "smaller" nodes within a level.

By default all nodes of one level are centered in the level. However one may also align them "towards the root" or "away from the root". When the root is located at the top this means the nodes are aligned "to the top of the level" or "to the bottom of the level".

Alignment in level when root is at the top

Center (Default)	TowardsRoot ("top of level")	AwayFromRoot ("bottom of level")

Alignment in level when root is at the left:

Table: Possible Alignments of Nodes (when root at left side)

Center (Default)	TowardsRoot ("left of level")	AwayFromRoot ("right of level")

Of cause the alignment also works when the root is at the bottom or at the right side.

Returns:Configuration.AlignmentInLevel

the alignment of "smaller" nodes within a level

Returns the size of the gap between subsequent levels.

Parameters

nextLevel:int

[nextLevel > 0]

Returns:double

the size of the gap between level (nextLevel-1) and nextLevel [result >= 0]

Returns the size of the minimal gap of nodes within a level.

In the layout there will be a gap of at least the returned size between both given nodes.

node1 and node2 are at the same level and are placed next to each other.

Parameters

node1:TreeNode

 

node2:TreeNode

 

Returns:double

the minimal size of the gap between node1 and node2 [result >= 0]

Returns the position of the root node in the diagram.

By default the root of the tree is located at the top of the diagram. However one may also put it at the left, right or bottom of the diagram.

Possible Root Positions

Top (Default)	Left	Right	Bottom

Returns:Configuration.Location

the position of the root node in the diagram
