Enum PartialReadException.CauseType

java.lang.Object

java.lang.Enum<PartialReadException.CauseType>

alluxio.client.file.dora.netty.PartialReadException.CauseType

All Implemented Interfaces:

Serializable, Comparable<PartialReadException.CauseType>

Enclosing class:

PartialReadException

public static enum PartialReadException.CauseType
extends Enum<PartialReadException.CauseType>

Possible causes of PartialReadException.

1. InterruptedException: client is waiting for the next packet but the thread is interrupted
2. TimeoutException: no new packets have been delivered in a long time, but the channel is considered still alive
3. AlluxioStatusException: server side error, channel is intact
4. Throwable (unknown exception): the channel is closed, or an unhandled exception in channel handler, etc., the channel is probably in a bad state to do any further I/O
5. IOException: exception when trying to write data into the output channel
6. EOFException: early eof, i.e. fewer bytes actually than expected

Except for 5, all the exceptions can be tried within the same channel.

Method Detail

values

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

Returns:

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

valueOf

public static PartialReadException.CauseType 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

getType

public Class<? extends Throwable> getType()

Returns:

the exception type
