Enum AutomatonInitialPartitioning

java.lang.Object

java.lang.Enum<AutomatonInitialPartitioning>

net.automatalib.util.partitionrefinement.AutomatonInitialPartitioning

All Implemented Interfaces:

Serializable, Comparable<AutomatonInitialPartitioning>

public enum AutomatonInitialPartitioning
extends Enum<AutomatonInitialPartitioning>

This enum allows to conveniently specify how the states of a deterministic automaton are initially partitioned when initializing the partition refinement data structure.

Enum Constant Summary

Enum Constants

Enum Constant and Description
BY_FULL_SIGNATURE States are initially partitioned by both their state properties and their transition properties.
BY_STATE_PROPERTY States are initially partitioned by their state property, i.e., states with the same state property are initially placed in the same partition class.
BY_TRANSITION_PROPERTIES States are initially partitioned by all of their transition properties, i.e., states with the same input symbol/transition property combinations are initially placed in the same partition class.

Enum Constant Detail

BY_STATE_PROPERTY

public static final AutomatonInitialPartitioning BY_STATE_PROPERTY

States are initially partitioned by their state property, i.e., states with the same state property are initially placed in the same partition class.

BY_TRANSITION_PROPERTIES

public static final AutomatonInitialPartitioning BY_TRANSITION_PROPERTIES

States are initially partitioned by all of their transition properties, i.e., states with the same input symbol/transition property combinations are initially placed in the same partition class. Note that if transitions are missing, a null property is assumed.

For constructing custom sink classifications required by the partial PaigeTarjanInitializers, please refer to the StateSignature methods.

BY_FULL_SIGNATURE

public static final AutomatonInitialPartitioning BY_FULL_SIGNATURE

States are initially partitioned by both their state properties and their transition properties. This mode can be regarded as a combination of BY_STATE_PROPERTY and BY_TRANSITION_PROPERTIES, resulting in the coarsest initial partition that refines both partitions obtained using the other modes.

For constructing custom sink classifications required by the partial PaigeTarjanInitializers, please refer to the StateSignature methods.

Method Detail

values

public static AutomatonInitialPartitioning[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (AutomatonInitialPartitioning c : AutomatonInitialPartitioning.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static AutomatonInitialPartitioning valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

initialClassifier

public abstract IntFunction<?> initialClassifier(UniversalDeterministicAutomaton.FullIntAbstraction<?,?,?> automaton)
