Method Detail

values

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

Returns:

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

valueOf

public static ThrowingJobGraphWriter 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

putJobGraph

public void putJobGraph(JobGraph jobGraph)

Description copied from interface: JobGraphWriter

Adds the JobGraph instance.

If a job graph with the same JobID exists, it is replaced.

Specified by:

putJobGraph in interface JobGraphWriter

removeJobGraph

public void removeJobGraph(org.apache.flink.api.common.JobID jobId)

Description copied from interface: JobGraphWriter

Removes the JobGraph with the given JobID if it exists.

Specified by:

removeJobGraph in interface JobGraphWriter

releaseJobGraph

public void releaseJobGraph(org.apache.flink.api.common.JobID jobId)

Description copied from interface: JobGraphWriter

Releases the locks on the specified JobGraph.

Releasing the locks allows that another instance can delete the job from the JobGraphStore.

Specified by:

releaseJobGraph in interface JobGraphWriter

Parameters:

jobId - specifying the job to release the locks for
