Class ArnCondition

java.lang.Object
  com.amazonaws.auth.policy.Condition
      com.amazonaws.auth.policy.conditions.ArnCondition

public class ArnCondition
extends Condition

AWS access control policy condition that allows an access control statement to be conditionally applied based on the comparison of an Amazon Resource Name (ARN).

An Amazon Resource Name (ARN) takes the following format: arn:aws:<vendor>:<region>:<namespace>:<relative-id>

• vendor identifies the AWS product (e.g., sns)
• region is the AWS Region the resource resides in (e.g., us-east-1), if any
• namespace is the AWS account ID with no hyphens (e.g., 123456789012)
• relative-id is the service specific portion that identifies the specific resource

For example, an Amazon SQS queue might be addressed with the following ARN: arn:aws:sqs:us-east-1:987654321000:MyQueue

Currently the only valid condition key to use in an ARN condition is ConditionFactory.SOURCE_ARN_CONDITION_KEY, which indicates the source resource that is modifying another resource, for example, an SNS topic is the source ARN when publishing messages from the topic to an SQS queue.

Constructor Detail

ArnCondition

public ArnCondition(ArnCondition.ArnComparisonType type,
                    String key,
                    String value)

Constructs a new access control policy condition that compares ARNs (Amazon Resource Names).

Parameters:

type - The type of comparison to perform.

key - The access policy condition key specifying where to get the first ARN for the comparison (ex: ConditionFactory.SOURCE_ARN_CONDITION_KEY).

value - The second ARN to compare against. When using ArnCondition.ArnComparisonType.ArnLike or ArnCondition.ArnComparisonType.ArnNotLike this may contain the multi-character wildcard (*) or the single-character wildcard (?).
