Enum Constant Detail

ServiceConfiguration

public static final ServiceConfigurationZNodeEnum ServiceConfiguration

A ServiceConfiguration znode.

LogicalService

public static final ServiceConfigurationZNodeEnum LogicalService

A logicalService.

PhysicalServicesContainer

public static final ServiceConfigurationZNodeEnum PhysicalServicesContainer

A container whose children are ephemeral znodes representing physical service instances.

MasterElection

public static final ServiceConfigurationZNodeEnum MasterElection

A container whose children are the physical services competing to become the master for a logical service.

MasterElectionLock

Method Detail

values

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

Returns:

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

valueOf

public static ServiceConfigurationZNodeEnum 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

getType

public static ServiceConfigurationZNodeEnum getType(String serviceConfigZPath,
                                                    String zpath)

Given the zpath of a ServiceConfiguration znode and another zpath, return the type of that other zpath.

Parameters:

serviceConfigZPath - The zpath of the ServiceConfiguration znode.

zpath - The other zpath.

Returns:

The type of the other znode.

Throws:

RuntimeException - if the other zpath can not be classified.
