Method Detail

createdAfter

public final Instant createdAfter()

The creation date and time beginning value filter for listing clusters.

Returns:

The creation date and time beginning value filter for listing clusters.

createdBefore

public final Instant createdBefore()

The creation date and time end value filter for listing clusters.

Returns:

The creation date and time end value filter for listing clusters.

clusterStates

public final List<ClusterState> clusterStates()

The cluster state filters to apply when listing clusters. Clusters that change state while this action runs may be not be returned as expected in the list of clusters.

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 hasClusterStates() method.

Returns:

The cluster state filters to apply when listing clusters. Clusters that change state while this action runs may be not be returned as expected in the list of clusters.

hasClusterStates

public final boolean hasClusterStates()

For responses, this returns true if the service returned a value for the ClusterStates 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.

clusterStatesAsStrings

public final List<String> clusterStatesAsStrings()

The cluster state filters to apply when listing clusters. Clusters that change state while this action runs may be not be returned as expected in the list of clusters.

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 hasClusterStates() method.

Returns:

The cluster state filters to apply when listing clusters. Clusters that change state while this action runs may be not be returned as expected in the list of clusters.

marker

public final String marker()

The pagination token that indicates the next set of results to retrieve.

Returns:

The pagination token that indicates the next set of results to retrieve.
