Method Detail

values

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

Returns:

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

valueOf

public static PackagedProgramUtils 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

createJobGraph

public static JobGraph createJobGraph(PackagedProgram packagedProgram,
                                      Configuration configuration,
                                      int defaultParallelism,
                                      @Nullable
                                      JobID jobID,
                                      boolean suppressOutput)
                               throws ProgramInvocationException

Creates a JobGraph with a specified JobID from the given PackagedProgram.

Parameters:

packagedProgram - to extract the JobGraph from

configuration - to use for the optimizer and job graph generator

defaultParallelism - for the JobGraph

jobID - the pre-generated job id

Returns:

JobGraph extracted from the PackagedProgram

Throws:

ProgramInvocationException - if the JobGraph generation failed

createJobGraph

public static JobGraph createJobGraph(PackagedProgram packagedProgram,
                                      Configuration configuration,
                                      int defaultParallelism,
                                      boolean suppressOutput)
                               throws ProgramInvocationException

Creates a JobGraph with a random JobID from the given PackagedProgram.

Parameters:

packagedProgram - to extract the JobGraph from

configuration - to use for the optimizer and job graph generator

defaultParallelism - for the JobGraph

suppressOutput - Whether to suppress stdout/stderr during interactive JobGraph creation.

Returns:

JobGraph extracted from the PackagedProgram

Throws:

ProgramInvocationException - if the JobGraph generation failed
