Enum Constant Detail

MOVING

public static final GridDhtPartitionState MOVING

Partition is being loaded from another node.

OWNING

public static final GridDhtPartitionState OWNING

This node is either a primary or backup owner.

RENTING

public static final GridDhtPartitionState RENTING

This node is neither primary or back up owner.

EVICTED

public static final GridDhtPartitionState EVICTED

Partition has been evicted from cache.

Method Detail

values

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

Returns:

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

valueOf

public static GridDhtPartitionState 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

fromOrdinal

@Nullable
public static @Nullable GridDhtPartitionState fromOrdinal(int ord)

Parameters:

ord - Ordinal value.

Returns:

Enum value.

active

public boolean active()

Returns:

True if state is active or owning.
