Modify the size or configurations of an instance group.

  • Method Details

    • instanceGroupId

      public final String instanceGroupId()

      Unique ID of the instance group to modify.

      Returns:
      Unique ID of the instance group to modify.

    • instanceCount

      public final Integer instanceCount()

      Target size for the instance group.

      Returns:
      Target size for the instance group.

    • hasEc2InstanceIdsToTerminate

      public final boolean hasEc2InstanceIdsToTerminate()
      For responses, this returns true if the service returned a value for the EC2InstanceIdsToTerminate property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • ec2InstanceIdsToTerminate

      public final List<String> ec2InstanceIdsToTerminate()

      The Amazon EC2 InstanceIds to terminate. After you terminate the instances, the instance group will not return to its original requested size.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasEc2InstanceIdsToTerminate() method.

      Returns:
      The Amazon EC2 InstanceIds to terminate. After you terminate the instances, the instance group will not return to its original requested size.

    • shrinkPolicy

      public final ShrinkPolicy shrinkPolicy()

      Policy for customizing shrink operations.

      Returns:
      Policy for customizing shrink operations.

    • reconfigurationType

      public final ReconfigurationType reconfigurationType()

      Type of reconfiguration requested. Valid values are MERGE and OVERWRITE.

      If the service returns an enum value that is not available in the current SDK version, reconfigurationType will return ReconfigurationType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from reconfigurationTypeAsString().

      Returns:
      Type of reconfiguration requested. Valid values are MERGE and OVERWRITE.
      See Also:

    • reconfigurationTypeAsString

      public final String reconfigurationTypeAsString()

      Type of reconfiguration requested. Valid values are MERGE and OVERWRITE.

      If the service returns an enum value that is not available in the current SDK version, reconfigurationType will return ReconfigurationType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from reconfigurationTypeAsString().

      Returns:
      Type of reconfiguration requested. Valid values are MERGE and OVERWRITE.

    • hasConfigurations

      public final boolean hasConfigurations()
      For responses, this returns true if the service returned a value for the Configurations property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • configurations

      public final List<Configuration> configurations()

      A list of new or modified configurations to apply for an instance group.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasConfigurations() method.

      Returns:
      A list of new or modified configurations to apply for an instance group.

    • toBuilder

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

    • builder

      public static InstanceGroupModifyConfig.Builder builder()

    • serializableBuilderClass

      public static Class<? extends InstanceGroupModifyConfig.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.
