Method Detail

values

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

Returns:

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

valueOf

public static ClientUtils 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

extractAndUploadJobGraphFiles

public static void extractAndUploadJobGraphFiles(JobGraph jobGraph,
                                                 org.apache.flink.util.function.SupplierWithException<BlobClient,IOException> clientSupplier)
                                          throws org.apache.flink.util.FlinkException

Extracts all files required for the execution from the given JobGraph and uploads them using the BlobClient from the given Supplier.

Parameters:

jobGraph - jobgraph requiring files

clientSupplier - supplier of blob client to upload files with

Throws:

org.apache.flink.util.FlinkException - if the upload fails

uploadJobGraphFiles

public static void uploadJobGraphFiles(JobGraph jobGraph,
