java.lang.Object

org.ginsim.service.tool.avatar.domain.ApproximateFinalPaths

All Implemented Interfaces:

FinalPaths

public class ApproximateFinalPaths
extends Object
implements FinalPaths

Approximate representation of the probabilities of the transitions within and going out of a cycle.
Useful when assuming that the transitions to the states out of a cycle are equiprobable (Uniform transitions).

Creates an empty cycle

Method Detail

addOutputPaths

public void addOutputPaths(Collection<String> states,
                           Collection<String> exits,
                           double prob)

Description copied from interface: FinalPaths

Creates transitions with uniform probability from a given cycle to its exits

Specified by:

addOutputPaths in interface FinalPaths

Parameters:

states - the states within the cycle

exits - the states accessible from the states within the cycle

prob - the uniform probability of the transitions between the all the cycle states and exit states

addOutputPaths

public void addOutputPaths(Collection<String> states,
                           Collection<String> exits,
                           double[][] prob)
                    throws AvatarLogicalModelException

Description copied from interface: FinalPaths

Inserts transitions from a given cycle to its exits

Specified by:

addOutputPaths in interface FinalPaths

Parameters:

states - the states within the cycle

exits - the states accessible from the states within the cycle

prob - a matrix specifying the probabilities of the transitions from the all the states of the cycle towards all the exit states

Throws:

AvatarLogicalModelException

getPaths

public Map<String,Double> getPaths(String state)

Description copied from interface: FinalPaths

Returns the transitions to reachable exit states from a given state in the cycle

Specified by:

getPaths in interface FinalPaths

Parameters:

state - the state in the cycle whose exits are to be computed

Returns:

the transitions to reachable exit states from a given state (the transitions maintain the keys of the exit states and the associated probability to reach them)
