Creates a new instance of Node.

Specified by:

create in class BaseEntityFactory<Node>

Parameters:

dataSet - The data set whose node list the node is contained within.

index - The offset to the start of the node within the string data structure.

reader - Binary reader positioned at the start of the Node.

Returns:

A new instance of a Node.

Throws:

IOException - if there was a problem accessing data file.

getBaseLength

public int getBaseLength()

Returns:

the basic length of a node for all supported versions.

getNodeNumericIndexLength

public int getNodeNumericIndexLength()

Returns:

The length of a numeric node index.

construct

protected abstract Node construct(Dataset dataSet,
                                  int index,
                                  BinaryReader reader)
