java.lang.Object

org.springframework.messaging.handler.CompositeMessageCondition

All Implemented Interfaces:

MessageCondition<CompositeMessageCondition>

public class CompositeMessageCondition
extends Object
implements MessageCondition<CompositeMessageCondition>

Composite MessageCondition that delegates to other message conditions.

For combine(CompositeMessageCondition) and compareTo(CompositeMessageCondition, Message) it is expected that the "other" composite contains the same number, type, and order of message conditions.

Since:

5.2

combine

public CompositeMessageCondition combine(CompositeMessageCondition other)

Description copied from interface: MessageCondition

Define the rules for combining this condition with another. For example combining type- and method-level conditions.

Specified by:

combine in interface MessageCondition<CompositeMessageCondition>

Parameters:

other - the condition to combine with

Returns:

the resulting message condition

getMatchingCondition

public @Nullable CompositeMessageCondition getMatchingCondition(Message<?> message)

Description copied from interface: MessageCondition

Check if this condition matches the given Message and returns a potentially new condition with content tailored to the current message. For example a condition with destination patterns might return a new condition with sorted, matching patterns only.

Specified by:

getMatchingCondition in interface MessageCondition<CompositeMessageCondition>

Returns:

a condition instance in case of a match; or null if there is no match.

compareTo

public int compareTo(CompositeMessageCondition other,
 Message<?> message)

Description copied from interface: MessageCondition

Compare this condition to another in the context of a specific message. It is assumed both instances have been obtained via MessageCondition.getMatchingCondition(Message) to ensure they have content relevant to current message only.

Specified by:

compareTo in interface MessageCondition<CompositeMessageCondition>

equals

public boolean equals(@Nullable Object other)

Overrides:

equals in class Object

hashCode
