- Method Detail
  - hasSecurityGroups
```
public final boolean hasSecurityGroups()
```
    For responses, this returns true if the service returned a value for the SecurityGroups 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.
  - securityGroups
```
public final List<GroupIdentifier> securityGroups()
```
    The security groups.
    
    If you specify a network interface, you must specify any security groups as part of the network interface instead of using this parameter.
    
    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 hasSecurityGroups() method.
    
    Returns:
    
    The security groups.
    
    If you specify a network interface, you must specify any security groups as part of the network interface instead of using this parameter.
  - addressingType
```
public final String addressingType()
```
    Deprecated.
    
    Returns:
    
    Deprecated.
  - hasBlockDeviceMappings
```
public final boolean hasBlockDeviceMappings()
```
    For responses, this returns true if the service returned a value for the BlockDeviceMappings 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.
  - blockDeviceMappings
```
public final List<BlockDeviceMapping> blockDeviceMappings()
```
    One or more block devices that are mapped to the Spot Instances. You can't specify both a snapshot ID and an encryption value. This is because only blank volumes can be encrypted on creation. If a snapshot is the basis for a volume, it is not blank and its encryption status is used for the volume encryption status.
    
    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 hasBlockDeviceMappings() method.
    
    Returns:

If a snapshot is the basis for a volume, it is not blank and its encryption status is used for the volume encryption status.
  - ebsOptimized
```
public final Boolean ebsOptimized()
```
    Indicates whether the instances are optimized for EBS I/O. This optimization provides dedicated throughput to Amazon EBS and an optimized configuration stack to provide optimal EBS I/O performance. This optimization isn't available with all instance types. Additional usage charges apply when using an EBS Optimized instance.
    
    Default: false
    
    Returns:

  - instanceType
```
public final InstanceType instanceType()
```
    The instance type.
    
    If the service returns an enum value that is not available in the current SDK version, instanceType will return InstanceType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from instanceTypeAsString().
    
    Returns:

public final boolean hasNetworkInterfaces()
```
    For responses, this returns true if the service returned a value for the NetworkInterfaces property.

  - networkInterfaces
```
public final List<InstanceNetworkInterfaceSpecification> networkInterfaces()
```
    The network interfaces.
    
    SpotFleetLaunchSpecification does not support Elastic Fabric Adapter (EFA). You must use LaunchTemplateConfig instead.
    
    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 hasNetworkInterfaces() method.

    Returns:
    
    The placement information.
  - ramdiskId
```
public final String ramdiskId()
```
    The ID of the RAM disk. Some kernels require additional drivers at launch. Check the kernel requirements for information about whether you need to specify a RAM disk. To find kernel requirements, refer to the Amazon Web Services Resource Center and search for the kernel ID.
    
    Returns:
    
    The ID of the RAM disk. Some kernels require additional drivers at launch. Check the kernel requirements for information about whether you need to specify a RAM disk. To find kernel requirements, refer to the Amazon Web Services Resource Center and search for the kernel ID.
  - spotPrice
```
public final String spotPrice()
```
    The maximum price per unit hour that you are willing to pay for a Spot Instance. We do not recommend using this parameter because it can lead to increased interruptions. If you do not specify this parameter, you will pay the current Spot price.
    
    If you specify a maximum price, your instances will be interrupted more frequently than if you do not specify this parameter.
    
    Returns:
    
    The maximum price per unit hour that you are willing to pay for a Spot Instance. We do not recommend using this parameter because it can lead to increased interruptions. If you do not specify this parameter, you will pay the current Spot price.

  - weightedCapacity
```
public final Double weightedCapacity()
```
    The number of units provided by the specified instance type. These are the same units that you chose to set the target capacity in terms of instances, or a performance characteristic such as vCPUs, memory, or I/O.
    
    If the target capacity divided by this value is not a whole number, Amazon EC2 rounds the number of instances to the next whole number. If this value is not specified, the default is 1.
    
    Returns:
    
    The number of units provided by the specified instance type. These are the same units that you chose to set the target capacity in terms of instances, or a performance characteristic such as vCPUs, memory, or I/O.

```
    For responses, this returns true if the service returned a value for the TagSpecifications 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.
  - tagSpecifications
```
public final List<SpotFleetTagSpecification> tagSpecifications()
```
    The tags to apply during creation.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
