java.lang.Object

java.lang.Enum<FuseIOOperation>

alluxio.stress.fuse.FuseIOOperation

All Implemented Interfaces:

Serializable, Comparable<FuseIOOperation>

public enum FuseIOOperation
extends Enum<FuseIOOperation>

Enum Constant Summary

Enum Constants

Enum Constant and Description
CLUSTER_READ Read <numAllFiles>/<numJobWorker> number of files evenly from all directories created by all job workers through local Fuse mount point.
LIST_FILE List the files before reading can help cache the metadata and gain more accurate reading performance, if client-side metadata cache is enabled.
LOCAL_READ Each job worker, or client, will read the files it wrote through local Fuse mount point.
REMOTE_READ Each job worker will evenly read the files written by other job workers via local Fuse mount point.
WRITE Write operation to test the write throughput or prepare data for reading.

Enum Constant Detail

CLUSTER_READ

public static final FuseIOOperation CLUSTER_READ

Read <numAllFiles>/<numJobWorker> number of files evenly from all directories created by all job workers through local Fuse mount point.

LIST_FILE

public static final FuseIOOperation LIST_FILE

List the files before reading can help cache the metadata and gain more accurate reading performance, if client-side metadata cache is enabled.

LOCAL_READ

public static final FuseIOOperation LOCAL_READ

Each job worker, or client, will read the files it wrote through local Fuse mount point.

REMOTE_READ

public static final FuseIOOperation REMOTE_READ

Each job worker will evenly read the files written by other job workers via local Fuse mount point.

WRITE

public static final FuseIOOperation WRITE

Write operation to test the write throughput or prepare data for reading.

Method Detail

values

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

Returns:

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

valueOf

public static FuseIOOperation 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

isRead

public static boolean isRead(FuseIOOperation operation)

Parameters:

operation - the operation

Returns:

true if the operation is a read

toString

public String toString()

Overrides:

toString in class Enum<FuseIOOperation>

fromString

public static FuseIOOperation fromString(String text)

Creates an instance type from the string. This method is case insensitive.

Parameters:

text - the instance type in string

Returns:

the created instance
