All Implemented Interfaces:
Serializable
public class EmbeddedDocumentUtil extends Object implements Serializable
Utility class to handle common issues with embedded documents.

Use statically if all that is needed is getting the EmbeddedDocumentExtractor. Otherwise, instantiate an instance.

Note: This is not thread safe. Make sure to instantiate one per thread.

    • getEmbeddedDocumentExtractor

      public static EmbeddedDocumentExtractor getEmbeddedDocumentExtractor(ParseContext context)
      This offers a uniform way to get an EmbeddedDocumentExtractor from a ParseContext. As of Tika 1.15, an AutoDetectParser will automatically be added to parse embedded documents if no Parser.class is specified in the ParseContext.

      If you'd prefer not to parse embedded documents, set Parser.class to EmptyParser in the ParseContext.

      Parameters:
      context -
      Returns:
      EmbeddedDocumentExtractor

    • getStatelessParser

      public static Parser getStatelessParser(ParseContext context)
      Utility function to get the Parser that was sent in to the ParseContext to handle embedded documents. If it is stateful, unwrap it to get its stateless delegating parser.

      If there is no Parser in the parser context, this will return null.

      Parameters:
      context -
      Returns:

    • getPasswordProvider

      public PasswordProvider getPasswordProvider()

    • getDetector

      public Detector getDetector()

    • getMimeTypes

      public MimeTypes getMimeTypes()

    • getTikaConfig

      public TikaConfig getTikaConfig()
      Returns:
      Returns a TikaConfig -- trying to find it first in the ParseContext that was included during initialization, and then creating a new one from via TikaConfig.getDefaultConfig() if it can't find one in the ParseContext. This caches the default config so that it only has to be created once.

    • tryToFindExistingLeafParser

      public static Parser tryToFindExistingLeafParser(Class clazz, ParseContext context)
      Tries to find an existing parser within the ParseContext. It looks inside of CompositeParsers and ParserDecorators. The use case is when a parser needs to parse an internal stream that is _part_ of the document, e.g. rtf body inside an msg.

      Can return null if the context contains no parser or the correct parser can't be found.

      Parameters:
      clazz - parser class to search for
      context -
      Returns:
