@Deprecated(since="2025-04-15") public abstract class AbstractBlob extends Object implements Blob
Deprecated.
The Jackrabbit Oak Memory library is designed for Oak-internal use only and thus deprecated. It will not be part of the AEM SDK after October 2025.
Abstract base class for Blob implementations. This base class provides default implementations for hashCode and equals.

  • Method Details

    • equal

      public static boolean equal(Blob a, Blob b)
      Deprecated.

    • getReference

      @Nullable public @Nullable String getReference()
      Deprecated.
      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()
      Deprecated.
      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

    • equals
