Class Arn

java.lang.Object

com.amazonaws.arn.Arn

public class Arn
extends Object

The ARNs generated and recognized by this code are the ARNs described here: https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html

The primary supported ARN format is: arn:<partition>:<service>:<region>:<account>:<resource>

To parse an ARN from a string use ARN.fromString(). To convert an ARN to it's string representation use ARN.toString(). For instance, for a string s, containing a well-formed ARN the following should always be true:

 ARN theArn = Arn.fromString(s);
 s.equals(theArn.toString());
 

Resources

getResourceAsString() returns everything after the account section of the ARN as a single string.

You can also retrieve the resource with the different resource parts using getResource(). This method returns a ArnResource which has access to ArnResource.getResourceType(), ArnResource.getResource() and ArnResource.getQualifier().

The following ARN formats are supported when parsing resources:

 arn:<partition>:<service>:<region>:<account>:resource
 arn:<partition>:<service>:<region>:<account>:<resourcetype>/resource
 arn:<partition>:<service>:<region>:<account>:<resourcetype>/resource:qualifier
 arn:<partition>:<service>:<region>:<account>:<resourcetype>:resource
 arn:<partition>:<service>:<region>:<account>:<resourcetype>:resource:qualifier
 

Some services use parent- and subresources which follow the format 'sub-resource-type/parent-resource/sub-resource'. In this case, the whole expression 'parent-resource/sub-resource' will be returned as the resource-id. An ARN using this pattern would be arn:<partition>:<service>:<region>:<account>:<resourcetype>/parent-resource/sub-resource which has a resource type and a resource but no qualifier.

Note:
Parsing permutations of any ARN formats not covered in tests or described as supported in documentation are at the user's own risk, as these use cases may change in the future.

Method Detail

getPartition

public String getPartition()

getService

public String getService()

getRegion

public String getRegion()

getAccountId

public String getAccountId()

getResource

public ArnResource getResource()

getResourceAsString

public String getResourceAsString()

toBuilder

public Arn.Builder toBuilder()

builder

public static Arn.Builder builder()

fromString

public static Arn fromString(String arn)

Parses a given string into an Arn. The resource is accessible entirely as a string through getResourceAsString(). Where correctly formatted, a parsed resource containing resource type, resource and qualifier is available through getResource().

Parameters:

arn - - A string containing an ARN.

Returns:

Arn - A modeled ARN.
