Enum Constant Detail

ADDITION

public static final SequencedMultiSetState.StateChangeType ADDITION

An element was added or appended to the state. The result will not contain any elements.

REMOVAL_NOT_FOUND

public static final SequencedMultiSetState.StateChangeType REMOVAL_NOT_FOUND

Nothing was removed (e.g. as a result of TTL or not matching key), the result will not contain any elements.

REMOVAL_ALL

public static final SequencedMultiSetState.StateChangeType REMOVAL_ALL

All elements were removed. The result will contain the last removed element.

REMOVAL_LAST_ADDED

public static final SequencedMultiSetState.StateChangeType REMOVAL_LAST_ADDED

The most recently added element was removed. The result will contain the element added before it.

REMOVAL_OTHER

public static final SequencedMultiSetState.StateChangeType REMOVAL_OTHER

An element was removed, it was not the most recently added, there are more elements. The result will not contain any elements

Method Detail

values

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

Returns:

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

valueOf

public static SequencedMultiSetState.StateChangeType 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

validate

public abstract <T> void validate(long sizeBefore,
                                  long sizeAfter,
                                  T payload)
