Check Object Availability

Using this SDK method, you can check if a particular object is present in the bucket, if the user has the required permissions to access the object. The Bucket reference used in the below code snippet is the component instance.

If you have enabled Versioning for your bucket, then you need to pass the versionID as the param, to check if a particular version of the object is available.

When you use this SDK method, you will get either of the following responses:

• true: If the object is available, the specified version is available, and if the user has the relevant permissions to access the objects.
• false:
  • If the object or the particular version of the object is not available in the bucket.
  • If the user does not have the required permissions to access the object.
  • If the bucket does not exist.
