Enum FuseIOOperation

  • All Implemented Interfaces:

    • Enum Constant Summary

      Enum Constants 
      Enum Constant 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.

    • 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:

      • valueOf

        public static FuseIOOperation valueOf​(java.lang.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:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null

      • isRead

        public static boolean isRead​(FuseIOOperation operation)
        Parameters:
        operation - the operation

        Overrides:
        toString in class java.lang.Enum<FuseIOOperation>

      • fromString

        public static FuseIOOperation fromString​(java.lang.String text)
