org.evrete.api.spi.MemoryScope

All Implemented Interfaces:

Serializable, Comparable<MemoryScope>, Constable

public enum MemoryScope
extends Enum<MemoryScope>

Defines memory scopes for use with instances of ReteMemory and provides utilities for iterating over state combinations based on these scopes.

Enum Constant Details

MAIN

public static final MemoryScope MAIN

Identifies main memory

DELTA

public static final MemoryScope DELTA

Identifies delta memory

Method Details

values

public static MemoryScope[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static MemoryScope valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null

states

public static Iterator<MemoryScope[]> states(MemoryScope scope,
 MemoryScope[] sharedResult)

Returns all state combinations depending on the provided scope. An array of MemoryScope is considered as a delta state if at least one value inside the array is DELTA

Parameters:

sharedResult - shared array for the iteration results
