Package org.apache.tika.parser.multiple

Class SupplementingParser

java.lang.Object

org.apache.tika.parser.AbstractParser

org.apache.tika.parser.multiple.AbstractMultipleParser

org.apache.tika.parser.multiple.SupplementingParser

All Implemented Interfaces:

Serializable, Parser

public class SupplementingParser
extends AbstractMultipleParser

Runs the input stream through all available parsers, merging the metadata from them based on the AbstractMultipleParser.MetadataPolicy chosen.

Warning - currently only one Parser should output any Content to the ContentHandler, the rest should only output Metadata. A solution to multiple-content is still being worked on...

Since:

Apache Tika 1.18
