[jira] [Commented] (TIKA-1527) Add payload to TikaInputStream

["Nick Burch (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TIKA-1527?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14287995#comment-14287995 ] 

Nick Burch commented on TIKA-1527:
----------------------------------

TikaInputStream already supports the concept of an ["Open Container"|https://tika.apache.org/1.7/api/org/apache/tika/io/TikaInputStream.html#getOpenContainer%28%29], which can be attached. The open container can be ignored by parsers, but it can save work when a detector spends some time parsing/processing a file to do detection, which the parser can then piggy-back off of. TikaInputStream will clean/close this container where possible when the overall input stream is closed.

Could that work here too?

> On TIKA-1511, I found a need to pass a Java object into a an EmbeddedDocumentExtractor.  I would have sent the object into the parser via ParseContext, but EmbeddedDocumentExtractor doesn't take a ParseContext, and it makes some sense that this object should be used instead of the actual TikaInputStream.
> I propose adding a payload to TikaInputStream that would only be used internally by parsers of container documents passing information to EmbeddedDocumentExtractors.
> Any problems with this or alternatives?
