Enum OutboundCorrelationStrategy

java.lang.Object

java.lang.Enum<OutboundCorrelationStrategy>

org.mule.runtime.extension.api.runtime.parameter.OutboundCorrelationStrategy

All Implemented Interfaces:

Serializable, Comparable<OutboundCorrelationStrategy>

public enum OutboundCorrelationStrategy
extends Enum<OutboundCorrelationStrategy>

Lists the possible strategies to determine the correlation id that should be sent on an outbound operation which supports correlation.

Operations should invoke the getOutboundCorrelationId(CorrelationInfo, String) method to obtain the actual value. If empty, then no correlation id should be sent.

Since:

1.1

Enum Constant Summary

Enum Constants

Enum Constant and Description
ALWAYS This strategy always yields a correlation id, regardless of CorrelationInfo.isOutboundCorrelationEnabled()
AUTO Whether to send a correlation id or not is defined by checking the CorrelationInfo.isOutboundCorrelationEnabled() method.
NEVER This strategy always returns Optional.empty()

Method Summary

Modifier and Type	Method and Description
abstract Optional<String>	getOutboundCorrelationId(CorrelationInfo correlationInfo, String customCorrelationId) Determines the correlation id that should be sent through an outbound operation (if any).
static OutboundCorrelationStrategy	valueOf(String name) Returns the enum constant of this type with the specified name.
static OutboundCorrelationStrategy[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

AUTO

public static final OutboundCorrelationStrategy AUTO

Whether to send a correlation id or not is defined by checking the CorrelationInfo.isOutboundCorrelationEnabled() method. If that method returns false, then an Optional.empty() value is returned. Otherwise, the same behavior as ALWAYS will be used

ALWAYS

public static final OutboundCorrelationStrategy ALWAYS

This strategy always yields a correlation id, regardless of CorrelationInfo.isOutboundCorrelationEnabled()

NEVER

public static final OutboundCorrelationStrategy NEVER

This strategy always returns Optional.empty()

Method Detail

values

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

Returns:

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

valueOf

public static OutboundCorrelationStrategy 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

getOutboundCorrelationId

public abstract Optional<String> getOutboundCorrelationId(CorrelationInfo correlationInfo,
                                                          String customCorrelationId)

Determines the correlation id that should be sent through an outbound operation (if any).

Depending on each strategy implementation, this method might return a customCorrelationId, the value of CorrelationInfo.getCorrelationId() or an Optional.empty() value.

Parameters:

correlationInfo - the current correlation info

customCorrelationId - a custom correlation id set at the operation level. Use null if no custom value defined

Returns:

an optioanl correlation id value
