public BlockFieldDocumentTreeNode(java.lang.String newTerm,
                                  int blockId,
                                  java.lang.String field)

field - the field containing the term.

BlockFieldDocumentTreeNode

public BlockFieldDocumentTreeNode(java.lang.String newTerm,
                                  int blockId,
                                  java.util.Set<java.lang.String> fields)

Deprecated.

Constructs a tree node for the given term, block id and the html tag.

Parameters:

newTerm - the term.

blockId - the block id.

fields - the fields that contain the term.

Method Detail

insertBlock

public boolean insertBlock(int blockId)

Deprecated.

Adds a block to the hashset of blocks already saved for this node

Parameters:

blockId - The id of the new block

Returns:

True if the blockid hasn't been seen before, false if we already had something at that block

getBlockIds

public int[] getBlockIds()

Deprecated.

Returns an array of the blocksids stored in this object. Sorted using Arrays.sort()

Returns:

integer array of sorted ascending blockids

getBlockCount

public int getBlockCount()

Deprecated.

Returns how many separate blocks does this term occur in. This should be the same as the term frequency if the block size == 1.

Returns:

integer of how many different blocks this terms occurs in.
