Method Detail

id

public final String id()

The unique identifier for the instance in Amazon EMR.

Returns:

The unique identifier for the instance in Amazon EMR.

ec2InstanceId

public final String ec2InstanceId()

The unique identifier of the instance in Amazon EC2.

Returns:

The unique identifier of the instance in Amazon EC2.

publicDnsName

public final String publicDnsName()

The public DNS name of the instance.

Returns:

The public DNS name of the instance.

publicIpAddress

public final String publicIpAddress()

The public IP address of the instance.

Returns:

The public IP address of the instance.

privateDnsName

public final String privateDnsName()

The private DNS name of the instance.

Returns:

The private DNS name of the instance.

privateIpAddress

public final String privateIpAddress()

The private IP address of the instance.

Returns:

The private IP address of the instance.

status

public final InstanceStatus status()

The current status of the instance.

Returns:

The current status of the instance.

instanceGroupId

public final String instanceGroupId()

The identifier of the instance group to which this instance belongs.

Returns:

The identifier of the instance group to which this instance belongs.

instanceFleetId

public final String instanceFleetId()

The unique identifier of the instance fleet to which an Amazon EC2 instance belongs.

Returns:

The unique identifier of the instance fleet to which an Amazon EC2 instance belongs.

market

public final MarketType market()

The instance purchasing option. Valid values are ON_DEMAND or SPOT.

If the service returns an enum value that is not available in the current SDK version, market will return MarketType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from marketAsString().

Returns:

The instance purchasing option. Valid values are ON_DEMAND or SPOT.

See Also:

MarketType

marketAsString

public final String marketAsString()

The instance purchasing option. Valid values are ON_DEMAND or SPOT.

If the service returns an enum value that is not available in the current SDK version, market will return MarketType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from marketAsString().

Returns:

The instance purchasing option. Valid values are ON_DEMAND or SPOT.

See Also:

MarketType

instanceType

public final String 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 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.

ebsVolumes

public final List<EbsVolume> 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.
