Package org.springframework.messaging.handler

Class CompositeMessageCondition

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(org.springframework.messaging.handler.CompositeMessageCondition) and compareTo(org.springframework.messaging.handler.CompositeMessageCondition, org.springframework.messaging.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

@Nullable
public 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

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
