Method Detail

values

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

Returns:

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

valueOf

public static JobCreator 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

submissionMillis - At what time submission of this simulated job be done

jobdesc - JobStory obtained from trace

outRoot - gridmix output directory

ugi - UGI of job submitter of this simulated job

seq - job sequence number

Returns:

the created simulated job

Throws:

IOException
