Package org.apache.tika.extractor
Class ParserContainerExtractor
java.lang.Object
org.apache.tika.extractor.ParserContainerExtractor
- All Implemented Interfaces:
Serializable
,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.- See Also:

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 interfaceContainerExtractor
- Parameters:
stream
- the document stream (input)recurseExtractor
- the extractor to use on any embedded containershandler
- handler for the embedded files (output)- Throws:
IOException
- if the document stream could not be readTikaException
- if the container could not be parsed
