LeafNode.FloatLeafNode

public LeafNode.FloatLeafNode(float[] data)

Method Detail

getAllData

public java.lang.Object getAllData()

Get all data in this leaf

Specified by:

getAllData in class LeafNode

Returns:

the mean/standard deviation value contained in this leaf

fillData

protected void fillData(java.lang.Object target,
                        int pos,
                        int len)

Description copied from class: LeafNode

Write this node's data into the target object at pos, making sure that exactly len data are written. The type of data written depends on the type of nodes; for example, when IntArrayLeafNodes are used, target would be an int[].

Specified by:

fillData in class LeafNode

pos - the position in the target at which to start writing

len - the amount of data items to write, usually equals getNumberOfData().

getNumberOfData

public int getNumberOfData()

Description copied from class: LeafNode

Count all the data available at and below this node. The meaning of this depends on the type of nodes; for example, when IntArrayLeafNodes are used, it is the total number of ints that are saved in all leaf nodes below the current node.

Specified by:

getNumberOfData in class LeafNode

Returns:

an int counting the data below the current node, or -1 if such a concept is not meaningful.

toWagonFormat

public void toWagonFormat(java.io.DataOutputStream out,
                          java.lang.String extension,
                          java.io.PrintWriter pw)
                   throws java.io.IOException

Writes the Cart to the given DataOut in Wagon Format

Specified by:

toWagonFormat in class Node

Parameters:

out - the outputStream

extension - the extension that is added to the last daughter

Throws:

java.io.IOException

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
