Record Class ExternalSummary

java.lang.Object
java.lang.Record
org.hyperledger.besu.plugin.services.metrics.ExternalSummary
Record Components:
count - the number of observations
sum - the sum of all the observations
quantiles - a list of quantiles with values

public record ExternalSummary(long count, double sum, List<ExternalSummary.Quantile> quantiles) extends Record
Record of summary data the is kept outside the metric system. Useful when existing libraries calculate the summary data on their own, and we want to export that summary via the configured metric system. A notable example are RocksDB statistics.
  • Constructor Details

    • ExternalSummary

      public ExternalSummary(long count, double sum, List<ExternalSummary.Quantile> quantiles)
      Creates an instance of a ExternalSummary record class.
      Parameters:
      count - the value for the count record component
      sum - the value for the sum record component
      quantiles - the value for the quantiles record component
  • 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 the compare method from their corresponding wrapper classes.
      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.
    • count

      public long count()
      Returns the value of the count record component.
      Returns:
      the value of the count record component
    • sum

      public double sum()
      Returns the value of the sum record component.
      Returns:
      the value of the sum record component
    • quantiles

      public List<ExternalSummary.Quantile> quantiles()
      Returns the value of the quantiles record component.
      Returns:
      the value of the quantiles record component
