Class ParserContainerExtractor

All Implemented Interfaces:
Serializable, ContainerExtractor

public class ParserContainerExtractor extends Object implements ContainerExtractor
An implementation of ContainerExtractor powered by the regular Parser API. This allows you to easily extract out all the embedded resources from within container files supported by normal Tika parsers. By default the AutoDetectParser will be used, to allow extraction from the widest range of containers.

      public boolean isSupported(TikaInputStream input) throws IOException
      Description copied from interface: ContainerExtractor
      Is this Container Extractor able to process the supplied container?
      Specified by:
      isSupported in interface ContainerExtractor
    • extract

      public void extract(TikaInputStream stream, ContainerExtractor recurseExtractor, EmbeddedResourceHandler handler) throws IOException, TikaException
      Description copied from interface: ContainerExtractor
      Processes a container file, and extracts all the embedded resources from within it.

      The EmbeddedResourceHandler you supply will be called for each embedded resource in the container. It is up to you whether you process the contents of the resource or not.

      The given document stream is consumed but not closed by this method. The responsibility to close the stream remains on the caller.

      If required, nested containers (such as a .docx within a .zip) can automatically be recursed into, and processed inline. If no recurseExtractor is given, the nested containers will be treated as with any other embedded resources.

      Specified by:
      extract in interface ContainerExtractor
      stream - the document stream (input)
      recurseExtractor - the extractor to use on any embedded containers
      handler - handler for the embedded files (output)
      IOException - if the document stream could not be read
      TikaException - if the container could not be parsed
