  +--ostore.oil.HMM.Segment

All Implemented Interfaces:

QueueElementIF, QuickSerializable, SegmentedModel.Segment

Enclosing class:

HMM

public static class HMM.Segment

extends Object

implements SegmentedModel.Segment

A Segment object contains the internal model state associated with a single state. It can be used to swap the information to/from an HMM.

Field Detail

state

public QuickSerializable state

The ID for the state whose information is stored in Segment.

marginal

public double marginal

Estimated marginal count for this state

transitions

public Array transitions

Estimated count of transitions out of this state.

emissions

public Array emissions

Estimated count of output emissions from this state.

Constructor Detail

HMM.Segment

public HMM.Segment(QuickSerializable state,
                   double marginal,
                   Array transitions,
                   Array emissions)

Create a new Segment.

Parameters:

state - The ID for the state whose information is stored in this Segment.

marginal - Estimated marginal count for this state

transitions - Estimated count of transitions out of this state.

emissions - Estimated count of output emissions from this state.

HMM.Segment

public HMM.Segment(InputBuffer buffer)
            throws QSException

Constructs a Segment from its serialized form.

Method Detail

id

public QuickSerializable id()

Description copied from interface: SegmentedModel.Segment

Returns the unique ID for this Segment. This ID serves as the only key identifying a Segment - Segment.equals should never be called. (Segment.id()).equals and (Segment.id()).hashCode, however, may be called quite often. Avoid using QuickSerializable IDs for which those methods are expensive.

Specified by:

id in interface SegmentedModel.Segment

Returns:

the unique ID for this Segment.

serialize

public void serialize(OutputBuffer buffer)

Description copied from interface: QuickSerializable

Add the object to the buffer.

Specified by:

serialize in interface QuickSerializable

Parameters:

buffer - the output buffer to add the object to
