java.lang.Object

java.lang.Enum<InputStreamType>

org.apache.hadoop.fs.s3a.impl.streams.InputStreamType

All Implemented Interfaces:

Serializable, Comparable<InputStreamType>

public enum InputStreamType
extends Enum<InputStreamType>

Enum of input stream types.

Each enum value contains the factory function actually used to create the factory.

Enum Constant Detail

Classic

public static final InputStreamType Classic

The classic input stream.

Prefetch

public static final InputStreamType Prefetch

The prefetching input stream.

Analytics

public static final InputStreamType Analytics

The analytics input stream.

Custom

public static final InputStreamType Custom

The a custom input stream.

Method Detail

values

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

Returns:

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

valueOf

public static InputStreamType 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

getName

public String getName()

String name.

Returns:

the name

streamID

public int streamID()

Get the ID of this stream. Isolated from the enum ID in case it ever needs to be tuned.

Returns:

the numeric ID of the stream.

capability

public String capability()

Get the capability string for this stream type.

Returns:

the name of a string to probe for.

factory

public Function<org.apache.hadoop.conf.Configuration,ObjectInputStreamFactory> factory()

Factory constructor.

Returns:

the factory function associated with this stream type.
