Method Detail

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.
