public interface ILargeEncodedTextExtractor : IContentExtractor,
IDisposable- Implements
- IContentExtractor, IDisposable
Remarks
"Large" is a subjective term defined by the LargeDocumentCritera property value.
This content extractor interface will not set the ExtractedText property due to the "large" size of the encoded text file.
The only content that this extractor extracts is MD5BinaryHash, SHA1BinaryHash, and SHA256BinaryHash hashes of the document. If ExtractContent(Stream)Stream argument 'textFileOutputStream' is not null, then this content extractor interface will also write the encoded text contents of this file to the supplied stream as either UTF-16 or UTF-8 encoding (which unicode encoding depends on UseLargeDocumentUTF16Encoding).
Writing the original encoded file to a new Stream (SHOULD be FileStream due to "large" size of file) is only really useful if file is not already in a easily indexable unicode encoding.

Methods
| Dispose | Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. (Inherited from IDisposable) |
| ExtractContent | Extracts content from a "large" encoded text file and optionally writes encoded text contents of this file to the supplied stream as either UTF-16 or UTF-8 encoding (which unicode encoding depends on UseLargeDocumentUTF16Encoding). |
| OverrideContentExtractionSettings |
Allows for overriding the ContentExtractionSettings object used by a IContentExtractor instance that was returned by a call to
OpenDiscoverSDK.ContentExtractorFactory.GetContentExtractor. See remarks for limitations.
(Inherited from IContentExtractor) |
Events
| ContentExtractionHeartbeat |
Notification event that lets implementers of IContentExtractor know that content extraction is still under process. See remarks.
