Enum Constant Detail

WRITE

public static final FuseIOOperation WRITE

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

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.

READ

public static final FuseIOOperation READ

Now only streaming reading is supported, that is, sequentially read the written files.

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(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

Returns:

true if the operation is a read

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<FuseIOOperation>

fromString

public static FuseIOOperation fromString(java.lang.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
