    • market

      public final MarketType market()

      The instance purchasing option. Valid values are ON_DEMAND or SPOT.

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

      Returns:
      The instance purchasing option. Valid values are ON_DEMAND or SPOT.

    • marketAsString

      public final String marketAsString()

      The instance purchasing option. Valid values are ON_DEMAND or SPOT.

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

    • instanceType

      public final String instanceType()

      The Amazon EC2 instance type, for example m3.xlarge.

      Returns:
      The Amazon EC2 instance type, for example m3.xlarge.

    • hasEbsVolumes

      public final boolean hasEbsVolumes()
      For responses, this returns true if the service returned a value for the EbsVolumes 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.

    • ebsVolumes

      public final List<EbsVolume> ebsVolumes()

      The list of Amazon EBS volumes that are attached to this instance.

      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 hasEbsVolumes() method.

      Returns:
      The list of Amazon EBS volumes that are attached to this instance.

    • toBuilder

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

    • builder

      public static Instance.Builder builder()

    • serializableBuilderClass

      public static Class<? extends Instance.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.
