Method Detail

values

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

Returns:

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

valueOf

public static KubernetesJobGraphStoreUtil 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

nameToJobID

public JobID nameToJobID(String key)

Convert a key in ConfigMap to JobID. The key is stored with prefix Constants.JOB_GRAPH_STORE_KEY_PREFIX.

Specified by:

nameToJobID in interface JobGraphStoreUtil

Parameters:

key - job graph key in ConfigMap.

Returns:

the parsed JobID.

jobIDToName

public String jobIDToName(JobID jobID)

Convert a JobID to config map key. We will add prefix Constants.JOB_GRAPH_STORE_KEY_PREFIX.

Specified by:

jobIDToName in interface JobGraphStoreUtil

Parameters:

jobID - job id

Returns:

a key to store job graph in the ConfigMap
