Enum InequalVersionComparisonResult

java.lang.Object

java.lang.Enum<InequalVersionComparisonResult>

org.infinispan.container.versioning.InequalVersionComparisonResult

All Implemented Interfaces:

Serializable, Comparable<InequalVersionComparisonResult>

public enum InequalVersionComparisonResult
extends Enum<InequalVersionComparisonResult>

Versions can be compared to each other to result in one version being before, after or at the same time as another version. This is different from the JDK's Comparable interface, which is much more simplistic in that it doesn't differentiate between something that is the same versus equal-but-different.

5.1

Enum Constant Summary

Enum Constants

Enum Constant	Description
AFTER	Denotes a version that was created temporally after another version.
BEFORE	Denotes a version that was created temporally before another version.
CONFLICTING	Denotes a version that was created at the same time as another version, but is not equal.
EQUAL	Denotes that the two versions being compared are equal.

Method Summary

Modifier and Type	Method	Description
static InequalVersionComparisonResult	valueOf(String name)	Returns the enum constant of this type with the specified name.
static InequalVersionComparisonResult[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

BEFORE

public static final InequalVersionComparisonResult BEFORE

Denotes a version that was created temporally before another version.

AFTER

public static final InequalVersionComparisonResult AFTER

Denotes a version that was created temporally after another version.

EQUAL

public static final InequalVersionComparisonResult EQUAL

Denotes that the two versions being compared are equal.

CONFLICTING

public static final InequalVersionComparisonResult CONFLICTING

Denotes a version that was created at the same time as another version, but is not equal. This is only really useful when using a partition-aware versioning scheme, such as vector or Lamport clocks.

Method Detail

values

public static InequalVersionComparisonResult[] 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 (InequalVersionComparisonResult c : InequalVersionComparisonResult.values())
    System.out.println(c);

Returns:

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

valueOf

public static InequalVersionComparisonResult 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
