All Implemented Interfaces:

@Generated("software.amazon.awssdk:codegen") public final class MatchmakingRuleSet extends Object implements SdkPojo, Serializable, ToCopyableBuilder<MatchmakingRuleSet.Builder,MatchmakingRuleSet>

Set of rule statements, used with FlexMatch, that determine how to build your player matches. Each rule set describes a type of group to be created and defines the parameters for acceptable player matches.

A rule set may define the following elements for a match. For detailed information and examples showing how to construct a rule set, see Build a FlexMatch rule set.

  • Teams -- Required. A rule set must define one or multiple teams for the match and set minimum and maximum team sizes. For example, a rule set might describe a 4x4 match that requires all eight slots to be filled.

  • Player attributes -- Optional. These attributes specify a set of player characteristics to evaluate when looking for a match. Matchmaking requests that use a rule set with player attributes must provide the corresponding attribute values. For example, an attribute might specify a player's skill or level.

  • Rules -- Optional. Rules define how to evaluate potential players for a match based on player attributes. A rule might specify minimum requirements for individual players, teams, or entire matches. For example, a rule might require each player to meet a certain skill level, each team to have at least one player in a certain role, or the match to have a minimum average skill level. or may describe an entire group--such as all teams must be evenly matched or have at least one player in a certain role.

  • Expansions -- Optional. Expansions allow you to relax the rules after a period of time when no acceptable matches are found. This feature lets you balance getting players into games in a reasonable amount of time instead of making them wait indefinitely for the best possible match. For example, you might use an expansion to increase the maximum skill variance between players after 30 seconds.

    • ruleSetName

      public final String ruleSetName()

      A unique identifier for the matchmaking rule set

      Returns:
      A unique identifier for the matchmaking rule set

    • ruleSetArn

      public final String ruleSetArn()

      The Amazon Resource Name (ARN) that is assigned to a Amazon GameLift Servers matchmaking rule set resource and uniquely identifies it. ARNs are unique across all Regions. Format is arn:aws:gamelift:<region>::matchmakingruleset/<ruleset name>. In a GameLift rule set ARN, the resource ID matches the RuleSetName value.

      Returns:
      The Amazon Resource Name (ARN) that is assigned to a Amazon GameLift Servers matchmaking rule set resource and uniquely identifies it. ARNs are unique across all Regions. Format is arn:aws:gamelift:<region>::matchmakingruleset/<ruleset name>. In a GameLift rule set ARN, the resource ID matches the RuleSetName value.

    • ruleSetBody

      public final String ruleSetBody()

      A collection of matchmaking rules, formatted as a JSON string. Comments are not allowed in JSON, but most elements support a description field.

      Returns:
      A collection of matchmaking rules, formatted as a JSON string. Comments are not allowed in JSON, but most elements support a description field.

    • creationTime

      public final Instant creationTime()

      A time stamp indicating when this data object was created. Format is a number expressed in Unix time as milliseconds (for example "1469498468.057").

      Returns:
      A time stamp indicating when this data object was created. Format is a number expressed in Unix time as milliseconds (for example "1469498468.057").

    • toBuilder

      public MatchmakingRuleSet.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<MatchmakingRuleSet.Builder,MatchmakingRuleSet>
      Returns:
      a builder for type T

    • builder

      public static MatchmakingRuleSet.Builder builder()

    • serializableBuilderClass

      public static Class<? extends MatchmakingRuleSet.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class Object

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.

    • sdkFieldNameToField

      public final Map<String,SdkField<?>> sdkFieldNameToField()
      Specified by:
      sdkFieldNameToField in interface SdkPojo
      Returns:
      The mapping between the field name and its corresponding field.
