Constructor Details

#initialize(bucket_name, options = {}) {|_self| ... } ⇒ Bucket

options:

  • :check => true: if setting a :bucket option, the default behaviour is not to check whether the bucket actually exists on S3. If you pass this option, S33r will only set the bucket if it is on S3 and accessible; if it isn’t, an error is raised (NoSuchBucket).

  • :create => true: if the bucket doesn’t exist, try to create it. S33r will check before trying to create the bucket and will just return the bucket if it does.

Yields:

  • (_self)

Yield Parameters:

  • _self (S33r::Bucket) —

    the object that the method was called on

end

#delete(key, options = {}) ⇒ Object

Delete a key from inside the bucket.
