Method Details
-
stackId
A stack ID. If you use this parameter,
DescribeInstances
returns descriptions of the instances associated with the specified stack.- Returns:
- A stack ID. If you use this parameter,
DescribeInstances
returns descriptions of the instances associated with the specified stack.
-
layerId
A layer ID. If you use this parameter,
DescribeInstances
returns descriptions of the instances associated with the specified layer.- Returns:
- A layer ID. If you use this parameter,
DescribeInstances
returns descriptions of the instances associated with the specified layer.
-
hasInstanceIds
public final boolean hasInstanceIds()For responses, this returns true if the service returned a value for the InstanceIds property. This DOES NOT check that the value is non-empty (for which, you should check theisEmpty()
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. -
instanceIds
An array of instance IDs to be described. If you use this parameter,
DescribeInstances
returns a description of the specified instances. Otherwise, it returns a description of every 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
hasInstanceIds()
method.- Returns:
- An array of instance IDs to be described. If you use this parameter,
DescribeInstances
returns a description of the specified instances. Otherwise, it returns a description of every instance.

equalsBySdkFields
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 anSdkPojo
class, and is generated based on a service model.If an
SdkPojo
class does not have any inherited fields,equalsBySdkFields
andequals
are essentially the same.- Specified by:
equalsBySdkFields
in interfaceSdkPojo
- Parameters:
obj
- the object to be compared with- Returns:
- true if the other object equals to this object by sdk fields, false otherwise.

getValueForField
Description copied from class:SdkRequest
Used to retrieve the value of a field from any class that extendsSdkRequest
. 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, theSdkRequest.getValueForField(String, Class)
method will again be available.- Overrides:
getValueForField
in classSdkRequest
- 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
-
sdkFieldNameToField
- Specified by:
sdkFieldNameToField
in interfaceSdkPojo
- Returns:
- The mapping between the field name and its corresponding field.
