values
public static DaemonType[] 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 (DaemonType c : DaemonType.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static DaemonType 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 nameNullPointerException
- if the argument is null
-

public List<org.apache.storm.shade.org.apache.zookeeper.data.ACL> getDefaultZkAcls(Map<String,Object> conf)
Get the default ZK ACLs that should be used for a given daemon type.- Parameters:
conf
- the config used to help get the correct ACLs.- Returns:
- the list of acls. null means no acls.
-
getZkSecretAcls
public List<org.apache.storm.shade.org.apache.zookeeper.data.ACL> getZkSecretAcls(WorkerTokenServiceType type, Map<String,Object> conf)
