  • Method Details

    • getNewStream

      @NotNull public @NotNull InputStream getNewStream()
      Description copied from interface: Blob
      Returns a new stream for this blob. The streams returned from multiple calls to this method are byte wise equals. That is, subsequent calls to read return the same sequence of bytes as long as neither call throws an exception.
      Specified by:
      getNewStream in interface Blob
      Returns:
      a new stream for this blob

    • length

      public long length()
      Description copied from interface: Blob
      Returns the length of this blob or -1 if unknown.
      Specified by:
      length in interface Blob
      Returns:
      the length of this blob.

    • getReference

      @Nullable public @Nullable String getReference()
      Description copied from interface: Blob
      Returns a secure reference to this blob, or null if such a reference is not available.
      Specified by:
      getReference in interface Blob
      Returns:
      binary reference, or null

    • getContentIdentity

      public String getContentIdentity()
      Description copied from interface: Blob
      A unique identifier of the content of this value. Usually this is a message digest of the content (a cryptographically secure one-way hash). This allows to avoid processing large binary values multiple times.

      This method returns null if the identifier is unknown. The identifier may not always be available, for example if the value has not yet been saved or processed. Once an identifier is available, it will never change because values are immutable.

      If two values have the same identifier, the content of the value is guaranteed to be the same. However it is not guaranteed that two values with the same content will return the same identifier.

      The identifier is opaque, meaning it can have any format and size.

      Specified by:
      getContentIdentity in interface Blob
      Returns:
      the unique identifier or null

    • isInlined

      public boolean isInlined()
      Description copied from interface: Blob
      Checks if the external blob is inlined in the id itself
      Specified by:
      isInlined in interface Blob
      Returns:

    • getBlobId

      public String getBlobId()

    • getBlobStore

      public BlobStore getBlobStore()
