com.apple.foundationdb.kmeans.PartitionEvaluator.Decision

All Implemented Interfaces:

Serializable, Comparable<PartitionEvaluator.Decision>, Constable

Enclosing class:

PartitionEvaluator

public static enum PartitionEvaluator.Decision
extends Enum<PartitionEvaluator.Decision>

The verdict PartitionEvaluator.evaluate(java.util.List<V>, com.apple.foundationdb.kmeans.PartitionEvaluator.Partition<?>, java.util.List<V>, com.apple.foundationdb.kmeans.PartitionEvaluator.Partition<?>, com.apple.foundationdb.util.Lens<V, com.apple.foundationdb.linear.RealVector>, com.apple.foundationdb.kmeans.PartitionEvaluator.Parameters) returns about a candidate partitioning relative to the current one.

Enum Constant Details

KEEP_CURRENT

public static final PartitionEvaluator.Decision KEEP_CURRENT

The candidate is admissible but not better than the current partition.

ACCEPT_CANDIDATE

public static final PartitionEvaluator.Decision ACCEPT_CANDIDATE

The candidate improves on the current partition by enough to justify replacement.

INVALID_CANDIDATE

public static final PartitionEvaluator.Decision INVALID_CANDIDATE

The candidate is structurally invalid (e.g. cluster too small relative to threshold).

Method Details

values

public static PartitionEvaluator.Decision[] 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 PartitionEvaluator.Decision 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
