Package jebl.evolution.trees
Class CompactRootedTree
java.lang.Object
jebl.evolution.trees.CompactRootedTree
- All Implemented Interfaces:
Graph
,RootedTree
,Tree
,Attributable
A memory efficient rooted tree.
- Uses a compact representation for the tree structure based primarily on indices instead of pointers
and objects
- Minimize penalty for unused features. Trees not using attributes or edges do not require additional
per node/edge memory.
Limitations:
- Maximun of 2^16 nodes and 2^15 external nodes. This should not be a problem with the current
sizes of phlogenetic trees we currently handle.
- Some of the accessors are slower, typically the ones getting all nodes, all edges, all internal
nodes etc. Traversing the tree and handling attributes speed should be fine (compared to SimpkeRootedTree)

Method Details
-
getChildren
- Specified by:
getChildren
in interfaceRootedTree
- Parameters:
node
- the node whose children are being requested.- Returns:
- the list of nodes that are the children of the given node. The set may be empty for a terminal node (a tip).
-
hasHeights
public boolean hasHeights()- Specified by:
hasHeights
in interfaceRootedTree
- Returns:
- Whether this tree has node heights available
-
getHeight
- Specified by:
getHeight
in interfaceRootedTree
- Parameters:
node
- the node whose height is being requested.- Returns:
- the height of the given node. The height will be less than the parent's height and greater than it children's heights.
-
hasLengths
public boolean hasLengths()- Specified by:
hasLengths
in interfaceRootedTree
- Returns:
- Whether this tree has branch lengths available
-
getLength
- Specified by:
getLength
in interfaceRootedTree
- Parameters:
node
- the node whose branch length (to its parent) is being requested.- Returns:
- the length of the branch to the parent node (0.0 if the node is the root).
-
getParent
- Specified by:
getParent
in interfaceRootedTree
- Parameters:
node
- the node whose parent is requested- Returns:
- the parent node of the given node, or null if the node is the root node.
-
getParentEdge
-
getRootNode
Description copied from interface:RootedTree
The root of the tree has the largest node height of all nodes in the tree.- Specified by:
getRootNode
in interfaceRootedTree
- Returns:
- the root of the tree.
-
conceptuallyUnrooted
public boolean conceptuallyUnrooted()Description copied from interface:RootedTree
Due to current implementation limitations, trees store "branch" information in nodes. So, internally rooted trees are genetrated when un-rooted would be more natural. This should be removed. If this is a rooted tree then it is rooted. This can really only confuse things. Trees are unrooted, RootedTrees are rooted. This is not an implementation limitation. It may be that a RootedTree has an arbitrary root but it is still rooted. With a rooted tree, it is convenient to store branch information at the node (i.e., for the branch above the node) because there is no "branch" object. Andrew. This function will probably become deprecated once the "development" tree viewer becomes in sync with the main tree viewer branch and some method of handling this concept has been introduced. Until then, this method remains.- Specified by:
conceptuallyUnrooted
in interfaceRootedTree
- Returns:
- true if tree(s) are to be viewed as unrooted
