Uses of PPMNode in pt.tumba.ngram.compression

Fields in pt.tumba.ngram.compression declared as PPMNode

private PPMNode	PPMModel._contextNode Current context node.
private PPMNode[]	PPMModel._contexts Nodes at depth 1 in the model.
(package private) PPMNode	PPMNode._firstChild The first child of this node.
(package private) PPMNode	PPMNode._nextSibling The next sibling of this node.
private PPMNode	PPMModel._rootNode Root of the trie structure of counts.

Methods in pt.tumba.ngram.compression that return PPMNode

private static PPMNode	PPMModel.lookup(PPMNode node, byte[] bytes, int offset, int length) Looks up a node from the given bytes, offset and length starting from the specified node.
private PPMNode	PPMModel.lookupNode(int contextLength) Returns node from the current byte buffer of the specified context length, or null if there isn't one.
PPMNode	PPMNode.prune() Prunes this node and its children, returning null if the node's count is too low and pruning all children with counts too low.
private PPMNode	PPMNode.pruneSiblings() Prunes the siblings of this node, returning the next sibling or null if there aren't any.
private PPMNode	PPMNode.rescaleSiblings() Rescale the counts on this node and the siblings of this node.

Methods in pt.tumba.ngram.compression with parameters of type PPMNode

private static PPMNode

PPMModel.lookup(PPMNode node, byte[] bytes, int offset, int length) Looks up a node from the given bytes, offset and length starting from the specified node.

Constructors in pt.tumba.ngram.compression with parameters of type PPMNode
