Record Class TtlPolicy.AdaptiveTtl

java.lang.Object
java.lang.Record
com.loomcache.server.lease.TtlPolicy.AdaptiveTtl
Record Components:
minTtl - the minimum TTL duration
maxTtl - the maximum TTL duration (must be >= minTtl)
All Implemented Interfaces:
TtlPolicy
Enclosing interface:
TtlPolicy
public static record TtlPolicy.AdaptiveTtl(Duration minTtl, Duration maxTtl) extends Record implements TtlPolicy
Adaptive TTL policy: TTL based on access frequency.

Hot keys (frequently accessed) get longer TTL up to maxTtl. Less frequently accessed keys maintain minTtl. The exact adjustment mechanism is determined by the TtlManager implementation.

1.5

      maxTtl - the value for the maxTtl 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()

      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. All components in this record class are compared with Objects::equals(Object,Object).
      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.

    • minTtl

      public Duration minTtl()
      Returns the value of the minTtl record component.
      Returns:
      the value of the minTtl record component

    • maxTtl

      public Duration maxTtl()
      Returns the value of the maxTtl record component.
      Returns:
      the value of the maxTtl record component
