Constructor Detail

AbstractTikaParser

public AbstractTikaParser(Parser parser)

Creates a new Tika-based parser.

Parameters:

parser - Tika parser

Method Detail

initialize

public void initialize(ParseHints parserHints)

Description copied from interface: IHintsAwareParser

Initialize this parser with the given parse hints. While not mandatory, aware parsers are strongly encouraged to support applicable hints.

Specified by:

initialize in interface IHintsAwareParser

Parameters:

parserHints - configuration settings influencing parsing when possible or appropriate

parseDocument

public final List<ImporterDocument> parseDocument(ImporterDocument doc,
                                                  Writer output)
                                           throws DocumentParserException

Description copied from interface: IDocumentParser

Parses a document.

Specified by:

parseDocument in interface IDocumentParser

Parameters:

doc - importer document to parse

output - where to store extracted or modified content of the supplied document

Returns:

a list of first-level embedded documents, if any

Throws:

DocumentParserException - problem parsing document

modifyParseContext

protected void modifyParseContext(ParseContext parseContext)

Override to apply your own settings on the Tika ParseContext. The ParseContext is already configured before calling this method. Changing existing settings may cause failure. Only override if you know what you are doing. The default implementation does nothing.

Parameters:

parseContext - Tika parse context

addTikaMetadataToImporterMetadata

protected void addTikaMetadataToImporterMetadata(Metadata tikaMeta,
                                                 ImporterMetadata metadata)

createRecursiveParser

protected AbstractTikaParser.RecursiveParser createRecursiveParser(String reference,
                                                                   String contentType,
                                                                   Writer writer,
                                                                   ImporterMetadata metadata,
                                                                   CachedStreamFactory streamFactory)

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

isSplitEmbedded

@Deprecated
public boolean isSplitEmbedded()

Deprecated. Use initialize(ParseHints)

Gets whether embedded documents should be split to become "standalone" distinct documents.

Returns:

true if parser should split embedded documents.

setSplitEmbedded

@Deprecated
