Enum FileTransferType

java.lang.Object

java.lang.Enum<FileTransferType>

alluxio.network.netty.FileTransferType

All Implemented Interfaces:

Serializable, Comparable<FileTransferType>

@ThreadSafe
public enum FileTransferType
extends Enum<FileTransferType>

How a read response will transfer block data over the network. There is a difference in speed and memory consumption between the two. MAPPED is the default since at larger sizes it outperforms TRANSFER.

Enum Constant Summary

Enum Constant and Description
MAPPED Uses a MappedByteBuffer to transfer data over the network.
TRANSFER Uses FileChannel.transferTo(long, long, java.nio.channels.WritableByteChannel) to transfer data over the network.

Enum Constant Detail

MAPPED

public static final FileTransferType MAPPED

Uses a MappedByteBuffer to transfer data over the network.

TRANSFER

public static final FileTransferType TRANSFER

Uses FileChannel.transferTo(long, long, java.nio.channels.WritableByteChannel) to transfer data over the network.

Method Detail

values

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

Returns:

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

valueOf

public static FileTransferType 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
