SimpMessageTypeMessageCondition
public SimpMessageTypeMessageCondition(SimpMessageType messageType)
A constructor accepting a message type.- 参数:
messageType- the message type to match messages to
方法详细资料
getMessageType
public SimpMessageType getMessageType()
getContent
protected Collection<?> getContent()
从类复制的说明:AbstractMessageConditionReturn the collection of objects the message condition is composed of (e.g. destination patterns), nevernull.
getToStringInfix
protected String getToStringInfix()
从类复制的说明:AbstractMessageConditionThe notation to use when printing discrete items of content. For example " || " for URL patterns or " && " for param expressions.
combine
public SimpMessageTypeMessageCondition combine(SimpMessageTypeMessageCondition other)
从接口复制的说明:MessageConditionDefine the rules for combining this condition with another. For example combining type- and method-level conditions.- 参数:
other- the condition to combine with- 返回:
- the resulting message condition
getMatchingCondition
public SimpMessageTypeMessageCondition getMatchingCondition(Message<?> message)
从接口复制的说明:MessageConditionCheck 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.- 返回:
- a condition instance in case of a match; or
nullif there is no match.
compareTo
public int compareTo(SimpMessageTypeMessageCondition other, Message<?> message)
从接口复制的说明:MessageConditionCompare this condition to another in the context of a specific message. It is assumed both instances have been obtained viaMessageCondition.getMatchingCondition(Message)to ensure they have content relevant to current message only.
