FileTransferType (Alluxio Core - Common Utilities 295 API)

java.lang.Object
- java.lang.Enum<FileTransferType>
- - alluxio.network.netty.FileTransferType

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<FileTransferType>
```
@ThreadSafe
public enum FileTransferType
extends java.lang.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 Constants
Enum Constant	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.

Method Summary

- 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(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
