Record Class SubscriptionQueryRequest

java.lang.Object
java.lang.Record
io.axoniq.framework.springcloud.query.SubscriptionQueryRequest
Record Components:
identifier - the identifier of the query being sent, which every response to it carries back
type - the MessageType of the query, as its string form
payload - the query's payload as its converter wrote it, or null when it carries none
metadata - the query's metadata
priority - the priority the query was dispatched with, or null when it carried none
updateBufferSize - how many updates the answering member may hold for this subscriber before failing it
public record SubscriptionQueryRequest(String identifier, String type, @Nullable String payload, Map<String,@Nullable String> metadata, @Nullable Integer priority, int updateBufferSize) extends Record
A subscription query as one member sends it to another.

Carries the same fields as a QueryDispatchRequest, plus the one thing only a subscription needs: how many updates the answering member may hold for this subscriber.

Nothing here says anything about the initial result. That is a query like any other, asked for over the query endpoint once every member has registered its subscription.

  • Constructor Details

    • SubscriptionQueryRequest

      public SubscriptionQueryRequest(String identifier, String type, @Nullable String payload, Map<String,@Nullable String> metadata, @Nullable Integer priority, int updateBufferSize)
      Compact constructor requiring an identifier and type, and defaulting null metadata to empty so a request from a member that omits the field still reads.

  • Method Details

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with '=='.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.
