Enum Constant Detail

PERSISTENT

public static final CreateMode PERSISTENT
The znode will not be automatically deleted upon client's disconnect.


PERSISTENT_SEQUENTIAL

public static final CreateMode PERSISTENT_SEQUENTIAL
The znode will not be automatically deleted upon client's disconnect, and its name will be appended with a monotonically increasing number.


EPHEMERAL

public static final CreateMode EPHEMERAL
The znode will be deleted upon the client's disconnect.

Method Detail

values

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

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

valueOf

public static CreateMode 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

isEphemeral

public boolean isEphemeral()

isSequential

public boolean isSequential()

toFlag

public int toFlag()

fromFlag

public static CreateMode fromFlag(int flag)
                           throws KeeperException
Map an integer value to a CreateMode value

Throws:
KeeperException
