market
The instance purchasing option. Valid values are
ON_DEMAND
orSPOT
.If the service returns an enum value that is not available in the current SDK version,
market
will returnMarketType.UNKNOWN_TO_SDK_VERSION
. The raw value returned by the service is available frommarketAsString()
.- Returns:
- The instance purchasing option. Valid values are
ON_DEMAND
orSPOT
. - See Also:
-
marketAsString
The instance purchasing option. Valid values are
ON_DEMAND
orSPOT
.If the service returns an enum value that is not available in the current SDK version,
market
will returnMarketType.UNKNOWN_TO_SDK_VERSION
. The raw value returned by the service is available frommarketAsString()
.- Returns:
- The instance purchasing option. Valid values are
ON_DEMAND
orSPOT
. - See Also:
-
instanceType
The Amazon EC2 instance type, for example
m3.xlarge
.- Returns:
- The Amazon EC2 instance type, for example
m3.xlarge
.
-
hasEbsVolumes
public final boolean hasEbsVolumes()For responses, this returns true if the service returned a value for the EbsVolumes 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. -
ebsVolumes
The list of Amazon EBS volumes that are attached to this 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
hasEbsVolumes()
method.- Returns:
- The list of Amazon EBS volumes that are attached to this instance.
-
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:

in interfaceToCopyableBuilder<Instance.Builder,

- a builder for type T

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.
-
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. -
