  • Method Details

    • hasFilter

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

    • filter

      public final List<Filter> filter()

      The filters.

      • auto-placement - Whether auto-placement is enabled or disabled (on | off).

      • availability-zone - The Availability Zone of the host.

      • client-token - The idempotency token that you provided when you allocated the host.

      • host-reservation-id - The ID of the reservation assigned to this host.

      • instance-type - The instance type size that the Dedicated Host is configured to support.

      • state - The allocation state of the Dedicated Host (available | under-assessment | permanent-failure | released | released-permanent-failure).

      • tag-key - The key of a tag assigned to the resource. Use this filter to find all resources assigned a tag with a specific key, regardless of the tag value.

      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 hasFilter() method.

      Returns:
      The filters.

      • auto-placement - Whether auto-placement is enabled or disabled (on | off).

      • availability-zone - The Availability Zone of the host.

      • client-token - The idempotency token that you provided when you allocated the host.

      • host-reservation-id - The ID of the reservation assigned to this host.

      • instance-type - The instance type size that the Dedicated Host is configured to support.

      • state - The allocation state of the Dedicated Host (available | under-assessment | permanent-failure | released | released-permanent-failure).

      • tag-key - The key of a tag assigned to the resource. Use this filter to find all resources assigned a tag with a specific key, regardless of the tag value.

    • hasHostIds

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

    • hostIds

      public final List<String> hostIds()

      The IDs of the Dedicated Hosts. The IDs are used for targeted instance launches.

      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 hasHostIds() method.

      Returns:
      The IDs of the Dedicated Hosts. The IDs are used for targeted instance launches.

    • maxResults

      public final Integer maxResults()

      The maximum number of results to return for the request in a single page. The remaining results can be seen by sending another request with the returned nextToken value. This value can be between 5 and 500. If maxResults is given a larger value than 500, you receive an error.

      You cannot specify this parameter and the host IDs parameter in the same request.

      Returns:
      The maximum number of results to return for the request in a single page. The remaining results can be seen by sending another request with the returned nextToken value. This value can be between 5 and 500. If maxResults is given a larger value than 500, you receive an error.

      You cannot specify this parameter and the host IDs parameter in the same request.

    • nextToken

      public final String nextToken()

      The token to use to retrieve the next page of results.

      Returns:
      The token to use to retrieve the next page of results.

    • toBuilder

      public DescribeHostsRequest.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<DescribeHostsRequest.Builder,DescribeHostsRequest>
      Specified by:
      toBuilder in class Ec2Request
      Returns:
      a builder for type T

    • builder

      public static DescribeHostsRequest.Builder builder()

    • serializableBuilderClass

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

    • hashCode

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

    • equals

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

    • 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)
      Description copied from class: SdkRequest
      Used to retrieve the value of a field from any class that extends SdkRequest. The field name specified should match the member name from the corresponding service-2.json model specified in the codegen-resources folder for a given service. The class specifies what class to cast the returned value to. If the returned value is also a modeled class, the SdkRequest.getValueForField(String, Class) method will again be available.
      Overrides:
      getValueForField in class SdkRequest
      Parameters:
      fieldName - The name of the member to be retrieved.
      clazz - The class to cast the returned object to.
      Returns:
      Optional containing the casted return value

    • 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.
