Enum Constant Detail

NONE

public static final RebalanceType NONE

Used by local and invalidation cache modes. No state transfer is happening.

FOUR_PHASE

public static final RebalanceType FOUR_PHASE

Used by distributed and replicated caches. To guarantee consistent results and non-blocking reads, cache must undergo a series of 4 topology changes: STABLE → READ_OLD_WRITE_ALL → READ_ALL_WRITE_ALL → READ_NEW_WRITE_ALL → STABLE

TWO_PHASE

public static final RebalanceType TWO_PHASE

Used by scattered cache. In any topology, each segment has at most one owner and consistent results are achieved using extra synchronization of versions in ScatteredVersionManager. State transfer consists of two changes: STABLE → TRANSITORY → STABLE

Method Detail

values

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

Returns:

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

valueOf

public static RebalanceType 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

from

public static RebalanceType from(CacheMode cacheMode)
