class MyFile(MyBlob, File): (source)

View In Hierarchy

ZMS file blob class for managing binary and text files.

MyFile extends MyBlob with file-specific functionality including:

File Features:

  • Generic binary and text file storage
  • Support for documents, archives, code files, etc.
  • Content-type detection and management
  • File size tracking and reporting

Data Management:

  • Inherits blob storage from MyBlob (ZODB or MediaDB)
  • XML serialization with content-type attributes
  • Support for text-based content (CSS, JavaScript, SVG, etc.)
  • HTTP caching and range request handling

Uses OFS.File.File as the underlying Zope file storage mechanism.

Method toXml Serialize this file to xml-string.

Method __call__ Handle HTTP request for blob object (file/image).
Method __str__ Undocumented
Method equals Indicate whether another blob is equal to this one.
Method get_real_size Returns real size in ZODB.
Method getContentType Returns MIME-type (e.g. image/gif, text/xml).
Method getData Returns data.
Method getDataSizeStr Returns display string for file-size (kB). Deprecated: Use standard.getDataSizeStr(len) instead!
Method getDataURI Return the blob payload as a data URI.
Method getFilename Returns filename.
Method getHref Return the absolute URL for this blob.
Method getMediadbfile Returns mediadb-filename.
Method getMimeTypeIconSrc Returns the absolute-url of an icon representing the MIME-type of this MyBlob-object. Deprecated: Use zmscontext.getMimeTypeIconSrc(mt) instead!
Method getObjAttrs Return object attribute definitions for this blob.
Method on_setobjattr Persist blob data to MediaDB and detach acquisition wrappers when needed.
