    See Also:
    About Access Control Lists
  - owner
```
public Acl.Entity owner()
```
    Returns the blob's owner. This will always be the uploader of the blob.
  - size
```
public Long size()
```
    Returns the content length of the data in bytes.
    
    See Also:
    Content-Length
  - contentType
```
public String contentType()
```
    Returns the blob's data content type.
    
    See Also:
    Content-Type
  - contentEncoding
```
public String contentEncoding()
```
    Returns the blob's data content encoding.
    
    See Also:
    Content-Encoding
  - contentDisposition
```
public String contentDisposition()
```
    Returns the blob's data content disposition.
    
    See Also:
    Content-Disposition
  - contentLanguage
```
public String contentLanguage()
```
    Returns the blob's data content language.
    
    See Also:
    Content-Language
  - componentCount
```
public Integer componentCount()
```
    Returns the number of components that make up this blob. Components are accumulated through the Storage.compose(Storage.ComposeRequest) operation and are limited to a count of 1024, counting 1 for each non-composite component blob and componentCount for each composite component blob. This value is set only for composite blobs.

    Returns the blob's media download link.
  - metadata
```
public Map<String,String> metadata()
```
    Returns blob's user provided metadata.
  - generation
```
public Long generation()
```
    Returns blob's data generation. Used for blob versioning.
  - metageneration
```
public Long metageneration()
```
    Returns blob's metageneration. Used for preconditions and for detecting changes in metadata. A metageneration number is only meaningful in the context of a particular generation of a particular blob.
  - deleteTime
```
public Long deleteTime()
```
    Returns the deletion time of the blob.
  - updateTime
```
public Long updateTime()
```
    Returns the last modification time of the blob's metadata.
  - isDirectory
```
public boolean isDirectory()
```
    Returns true if the current blob represents a directory. This can only happen if the blob is returned by Storage.list(String, Storage.BlobListOption...) when the Storage.BlobListOption.currentDirectory() option is used. When this is the case only blobId() and size() are set for the current blob: BlobId.name() ends with the '/' character, BlobId.generation() returns null and size() is 0.
  - toBuilder
```
public BlobInfo.Builder toBuilder()
```
    Returns a builder for the current blob.
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - equals
```
public boolean equals(Object obj)
```
    Overrides:
    
    equals in class Object
  - builder
```
public static BlobInfo.Builder builder(BucketInfo bucketInfo,
                       String name)
```
    Returns a BlobInfo builder where blob identity is set using the provided values.
  - builder
```
public static BlobInfo.Builder builder(String bucket,
                       String name)
```
    Returns a BlobInfo builder where blob identity is set using the provided values.
  - builder
```
public static BlobInfo.Builder builder(BucketInfo bucketInfo,
                       String name,
                       Long generation)
```
    Returns a BlobInfo builder where blob identity is set using the provided values.
  - builder
```
public static BlobInfo.Builder builder(String bucket,
                       String name,
