java.lang.Object

java.lang.Enum<ErrorTypes>

org.apache.nifi.processor.util.pattern.ErrorTypes

All Implemented Interfaces:

Serializable, Comparable<ErrorTypes>

public enum ErrorTypes
extends Enum<ErrorTypes>

Represents general error types and how it should be treated.

Nested Class Summary

Nested Classes

Modifier and Type	Class and Description
static class	ErrorTypes.Destination Represents the destination of input.
static class	ErrorTypes.Penalty Indicating yield or penalize the processing when transfer the input.
static class	ErrorTypes.Result Result represents a result of a procedure.

Enum Constant Summary

Enum Constants

Enum Constant and Description
Defer The input was not ready for being processed.
InvalidInput The input will be sent to the failure route for recovery without penalizing.
PersistentFailure Procedure setting has to be fixed, otherwise the same error would occur irrelevant to the input.
TemporalFailure The procedure is temporarily unavailable, usually due to the external service unavailability.
TemporalInputFailure The input was not processed successfully due to some temporal error related to the specifics of the input.
UnknownFailure It is unknown whether the error is persistent or temporal, related to the input or not.

Enum Constant Detail

PersistentFailure

public static final ErrorTypes PersistentFailure

Procedure setting has to be fixed, otherwise the same error would occur irrelevant to the input. In order to NOT call failing process frequently, this should be yielded.

UnknownFailure

public static final ErrorTypes UnknownFailure

It is unknown whether the error is persistent or temporal, related to the input or not.

InvalidInput

public static final ErrorTypes InvalidInput

The input will be sent to the failure route for recovery without penalizing. Basically, the input should not be sent to the same procedure again unless the issue has been solved.

TemporalFailure

public static final ErrorTypes TemporalFailure

The procedure is temporarily unavailable, usually due to the external service unavailability. Retrying maybe successful, but it should be yielded for a while.

TemporalInputFailure

public static final ErrorTypes TemporalInputFailure

The input was not processed successfully due to some temporal error related to the specifics of the input. Retrying maybe successful, but it should be penalized for a while.

Defer

public static final ErrorTypes Defer

The input was not ready for being processed. It will be kept in the incoming queue and also be penalized.

destination

private final ErrorTypes.Destination destination

penalty

private final ErrorTypes.Penalty penalty

Method Detail

values

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

Returns:

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

valueOf

public static ErrorTypes 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

result

public ErrorTypes.Result result()

destination

public ErrorTypes.Destination destination()

penalty

public ErrorTypes.Penalty penalty()
