Constructor Detail

TikaLuceneContentExtractor

public TikaLuceneContentExtractor(Parser parser)

Create new Tika-based content extractor using the provided parser instance.

Parameters:

parser - parser instance

TikaLuceneContentExtractor

public TikaLuceneContentExtractor(Parser parser,
                                  boolean validateMediaType)

Create new Tika-based content extractor using the provided parser instance and optional media type validation. If validation is enabled, the implementation will try to detect the media type of the input and validate it against media typesthis.contentFieldName supported by the parser.

Parameters:

parser - parser instance

validateMediaType - enabled or disable media type validation

TikaLuceneContentExtractor

public TikaLuceneContentExtractor(Parser parser,
                                  LuceneDocumentMetadata documentMetadata)

Parameters:

parser - parser instancethis.contentFieldName

documentMetadata - documentMetadata

Method Detail

extract

public org.apache.lucene.document.Document extract(InputStream in)

Extract the content and metadata from the input stream. Depending on media type validation, the detector could be run against input stream in order to ensure that parser supports this type of content.

Parameters:

in - input stream to extract the content and metadata from

Returns:

the extracted document or null if extraction is not possible or was unsuccessful

extract

public org.apache.lucene.document.Document extract(InputStream in,
                                                   LuceneDocumentMetadata documentMetadata)

Extract the content and metadata from the input stream. Depending on media type validation, the detector could be run against input stream in order to ensure that parser supports this type of content.

Parameters:

in - input stream to extract the content and metadata from

documentMetadata - documentMetadata

Returns:

the extracted document or null if extraction is not possible or was unsuccessful

extractContent

public org.apache.lucene.document.Document extractContent(InputStream in)

Extract the content only from the input stream. Depending on media type validation, the detector could be run against input stream in order to ensure that parser supports this type of content.

Parameters:

in - input stream to extract the content from

Returns:

the extracted document or null if extraction is not possible or was unsuccessful

extractMetadata

public org.apache.lucene.document.Document extractMetadata(InputStream in)

Extract the metadata only from the input stream. Depending on media type validation, the detector could be run against input stream in order to ensure that parser supports this type of content.

Parameters:

in - input stream to extract the metadata from

Returns:

the extracted document or null if extraction is not possible or was unsuccessful

extractMetadata

public org.apache.lucene.document.Document extractMetadata(InputStream in,
                                                           LuceneDocumentMetadata documentMetadata)
