Method Detail

clusterId

public final String clusterId()

The ID of the cluster to which the instance group belongs.

Returns:

The ID of the cluster to which the instance group belongs.

hasInstanceGroups

public final boolean hasInstanceGroups()

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

instanceGroups

public final List<InstanceGroupModifyConfig> instanceGroups()

Instance groups to change.

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 hasInstanceGroups() method.

Returns:

Instance groups to change.

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

                                              Class<T> clazz)
