Class ScalingConstraints

java.lang.Object
software.amazon.awssdk.services.emr.model.ScalingConstraints
All Implemented Interfaces:
Serializable, SdkPojo, ToCopyableBuilder<ScalingConstraints.Builder,ScalingConstraints>
@Generated("software.amazon.awssdk:codegen") public final class ScalingConstraints extends Object implements SdkPojo, Serializable, ToCopyableBuilder<ScalingConstraints.Builder,ScalingConstraints>

The upper and lower Amazon EC2 instance limits for an automatic scaling policy. Automatic scaling activities triggered by automatic scaling rules will not cause an instance group to grow above or below these limits.

    • minCapacity

      public final Integer minCapacity()

      The lower boundary of Amazon EC2 instances in an instance group below which scaling activities are not allowed to shrink. Scale-in activities will not terminate instances below this boundary.

      Returns:
      The lower boundary of Amazon EC2 instances in an instance group below which scaling activities are not allowed to shrink. Scale-in activities will not terminate instances below this boundary.

    • maxCapacity

      public final Integer maxCapacity()

      The upper boundary of Amazon EC2 instances in an instance group beyond which scaling activities are not allowed to grow. Scale-out activities will not add instances beyond this boundary.

      Returns:
      The upper boundary of Amazon EC2 instances in an instance group beyond which scaling activities are not allowed to grow. Scale-out activities will not add instances beyond this boundary.

    • toBuilder

      public ScalingConstraints.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<ScalingConstraints.Builder,ScalingConstraints>
      Returns:
      a builder for type T

    • builder

      public static ScalingConstraints.Builder builder()

    • serializableBuilderClass

      public static Class<? extends ScalingConstraints.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.
