Class FTPosData

java.lang.Object
  org.basex.data.FTPosData

public final class FTPosData
extends java.lang.Object

This class provides a container for query fulltext positions for any visualization. The data is stored as follows: prepos[i][pre, pos0, ..., posn] poi[i][poiMax, poi0, ..., poin] For each pos values, theres a poi value stored. poiMax is the max value of all pos0, ..., poin

Method Detail

addFTAndCol

public void addFTAndCol(byte[] c)

Add a ftand color result.

Parameters:

c - int[] ftand color result

add

public void add(int[] pp,
                int[] p)

Adds a node. pp : [pre, pos0, ..., posn] p : [poiMax, poi0, ..., poin]

Parameters:

pp - int[] pre and positions

p - int[] pointer

get

public int[][] get(int pre)

Gets fulltext data from the container. If no data is stored for a pre value, null is returned. int[0] : [pos0, ..., posn] int[1] : [poi0, ..., poin]

Parameters:

pre - int pre value

Returns:

int[2][n] fulltext data or null

remove

public void remove(int pre)

Removes ftdata for this node.

Parameters:

pre - int pre value

addConvSeqData

public void addConvSeqData(IntList[] d,
                           int pre,
                           int div)

Converts data from sequential ftcontains processing.

Parameters:

d - IntList[] ftcontains data

pre - int pre value

div - int div to add for each pointer
