Interface ModelManager

All Superinterfaces:

FeatureManager, FeatureManagerEdge, FeatureManagerEdgeExplicitLength, FeatureManagerNode, FeatureManagerNodeExplicitLength, java.io.Serializable

All Known Implementing Classes:

BeanModel, Interval13Model, Interval29Model, ZeroOrderManager, ZeroOrderModel

public interface ModelManager
extends FeatureManagerEdge, FeatureManagerNode, FeatureManagerEdgeExplicitLength, FeatureManagerNodeExplicitLength

overall itnerface for an entire model. The model contains the hidden state defintions and transitions as well as all of the features.

Method Summary

DenseBooleanMatrix2D	getLegalTransitions() returns a boolean matrix where each (row, column) entry contains true if the model has a legal transition between state row and state column.
int	getNumStates() the number of hidden states.
int	getStateIndex(java.lang.String name) looks up a hidden state's index given it's human readable name.
java.lang.String	getStateName(int state) looks up the human readable name of a hidden state given it's index.

Method Detail

getNumStates

int getNumStates()

the number of hidden states.

Returns:

the number of hidden states

getStateName

java.lang.String getStateName(int state)

looks up the human readable name of a hidden state given it's index.

Returns:

string name of the state with this index.

getStateIndex

int getStateIndex(java.lang.String name)

looks up a hidden state's index given it's human readable name.

Returns:

index of the state with this name.

getLegalTransitions

DenseBooleanMatrix2D getLegalTransitions()

returns a boolean matrix where each (row, column) entry contains true if the model has a legal transition between state row and state column. A ModelManager may safely return null if all transitions are legal.

Returns:

a boolean matrix containing the legal transitions.
