Class RecursiveParserWrapperHandler

java.lang.Object

org.xml.sax.helpers.DefaultHandler

org.apache.tika.sax.AbstractRecursiveParserWrapperHandler

org.apache.tika.sax.RecursiveParserWrapperHandler

All Implemented Interfaces:

Serializable, ContentHandler, DTDHandler, EntityResolver, ErrorHandler

@Deprecated(since="2026-04-30")
public class RecursiveParserWrapperHandler
extends AbstractRecursiveParserWrapperHandler

Deprecated.

This version of the Apache Tika library is deprecated. Use your own version of Apache Tika.

This is the default implementation of AbstractRecursiveParserWrapperHandler. See its documentation for more details. This caches the a metadata object for each embedded file and for the container file. It places the extracted content in the metadata object, with this key: AbstractRecursiveParserWrapperHandler.TIKA_CONTENT If memory is a concern, subclass AbstractRecursiveParserWrapperHandler to handle each embedded document.

NOTE: This handler must only be used with the RecursiveParserWrapper

Constructor Details

RecursiveParserWrapperHandler

public RecursiveParserWrapperHandler(ContentHandlerFactory contentHandlerFactory)

Deprecated.

Create a handler with no limit on the number of embedded resources

RecursiveParserWrapperHandler

public RecursiveParserWrapperHandler(ContentHandlerFactory contentHandlerFactory,
 int maxEmbeddedResources)

Deprecated.

Create a handler that limits the number of embedded resources that will be parsed

Parameters:

maxEmbeddedResources - number of embedded resources that will be parsed

RecursiveParserWrapperHandler

public RecursiveParserWrapperHandler(ContentHandlerFactory contentHandlerFactory,
 int maxEmbeddedResources,
 int maxWriteLimit,
 org.apache.tika.metadata.filter.MetadataFilter metadataFilter)

Deprecated.

Method Details

startEmbeddedDocument

public void startEmbeddedDocument(ContentHandler contentHandler,
 Metadata metadata)
                           throws SAXException

Deprecated.

This is called before parsing an embedded document

Overrides:

startEmbeddedDocument in class AbstractRecursiveParserWrapperHandler

Parameters:

contentHandler - - local content handler to use on the embedded document

metadata - metadata to use for the embedded document

Throws:

SAXException

endEmbeddedDocument

public void endEmbeddedDocument(ContentHandler contentHandler,
 Metadata metadata)
                         throws SAXException

Deprecated.

This is called after parsing an embedded document.

Overrides:

endEmbeddedDocument in class AbstractRecursiveParserWrapperHandler

Parameters:

contentHandler - local contenthandler used on the embedded document

metadata - metadata from the embedded document

Throws:

SAXException

endDocument

public void endDocument(ContentHandler contentHandler,
 Metadata metadata)
                 throws SAXException

Deprecated.

Description copied from class: AbstractRecursiveParserWrapperHandler

This is called after the full parse has completed. Override this for custom behavior. Make sure to call this as super.endDocument(...) in subclasses because this adds whether or not the embedded resource maximum has been hit to the metadata.

Overrides:

endDocument in class AbstractRecursiveParserWrapperHandler

Parameters:

contentHandler - content handler used on the main document

metadata - metadata from the main document

Throws:

SAXException

getMetadataList

public List<Metadata> getMetadataList()

Deprecated.

Returns:

a list of Metadata objects, one for the main document and one for each embedded document
