Constructor Detail

TikaContentExtractor

public TikaContentExtractor()

Create new Tika-based content extractor using AutoDetectParser.

TikaContentExtractor

public TikaContentExtractor(org.apache.tika.parser.Parser parser)

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

Parameters:

parser - parser instance

TikaContentExtractor

public TikaContentExtractor(List<org.apache.tika.parser.Parser> parsers)

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

Parameters:

parsers - parser instances

TikaContentExtractor

public TikaContentExtractor(List<org.apache.tika.parser.Parser> parsers,
                            org.apache.tika.detect.Detector detector)

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

Parameters:

parsers - parser instances

TikaContentExtractor

public TikaContentExtractor(org.apache.tika.parser.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 parser will try to detect the media type of the input and validate it against media types supported by the parser.

Parameters:

parser - parser instance

validateMediaType - enabled or disable media type validationparser

Method Detail

extract

public TikaContentExtractor.TikaContent 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 content and metadata or null if extraction is not possible or was unsuccessful

extract

public TikaContentExtractor.TikaContent extract(InputStream in,
                                                javax.ws.rs.core.MediaType mt)

Extract the content and metadata from the input stream with a media type hint.

Parameters:

in - input stream to extract the content and metadata from

mt - JAX-RS MediaType of the stream content

Returns:

the extracted content and metadata or null if extraction is not possible or was unsuccessful

extract

public TikaContentExtractor.TikaContent extract(InputStream in,
                                                ContentHandler handler)

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

handler - custom ContentHandler

Returns:

the extracted content and metadata or null if extraction is not possible or was unsuccessful

extract

public TikaContentExtractor.TikaContent extract(InputStream in,
                                                ContentHandler handler,
                                                javax.ws.rs.core.MediaType mt)

Extract the content and metadata from the input stream with a media type hint.

Parameters:

in - input stream to extract the content and metadata from

handler - custom ContentHandler

mt - JAX-RS MediaType of the stream content

Returns:

the extracted content and metadata or null if extraction is not possible or was unsuccessful

extract

public TikaContentExtractor.TikaContent extract(InputStream in,
                                                ContentHandler handler,
                                                org.apache.tika.parser.ParseContext context)

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:

handler - custom ContentHandler

context - custom context

Returns:

the extracted content and metadata or null if extraction is not possible or was unsuccessful

extract

public TikaContentExtractor.TikaContent extract(InputStream in,
                                                ContentHandler handler,
