  org.javasimon.callback.calltree.CallTreeNode

public class CallTreeNode
extends Object

Call tree node is one Simon one for one call level, all splits for this Simon+Level(+Thread) tuple are kept for later analysis. Simon name is unique within parent tree node. Said differently a tree node can not have two children with same name.

Field Detail

name

private final String name

Name, used as a key.

splits

private final List<Split> splits

Splits. Size defaults to 1, because most of the time there are no loops.

children

private Map<String,CallTreeNode> children

Child tree nodes.

parent

private CallTreeNode parent

Parent tree node. null for root tree node.

Constructor Detail

CallTreeNode

Main constructor.

Parameters:

name - Simon name

Method Detail

getName

public String getName()

Returns Simon name.

Returns:

total time of splits

getPercent

public Integer getPercent()

Returns the part of time spent in this node compared to parent.

Returns:

Percent time

addChild

public CallTreeNode addChild(String name)

Adds a child to this tree node.

Parameters:

name - Child Simon name

Returns:

Created child node

getChild

public CallTreeNode getChild(String name)

getOrAddChild

public CallTreeNode getOrAddChild(String name)

Returns a child node with given name or creates it if it does not exists.

Parameters:

name - Simon name

Returns:

Child node

getParent

public CallTreeNode getParent()

Returns parent tree node.

Returns:

Parent tree node

print

private void print(PrintWriter printWriter,
                   String prefix,
                   Long parentTotal)

Recursively prints this tree node to given print writer.

Parameters:

printWriter - Output print writer

prefix - Line prefix (used internally for indentation)

parentTotal - Duration of parent node (used to compute duration ratio for child nodes), null for root nodes

print
