ClassDescriptionAn input stream reader that automatically detects the character encoding to be used for converting bytes to characters.Encoding detector that identifies the character set from a byte-order mark (BOM) at the start of the stream.Maps detected charsets to safer superset charsets for decoding.Content type detector that combines multiple different detection mechanisms.A composite encoding detector that runs child detectors.A composite detector that orchestrates the detection pipeline: MimeTypes (magic byte) detection Container and other detectors loaded via SPI TextDetector as fallback for unknown types Returns the most specific type detectedA composite encoding detector over all
EncodingDetectorimplementations available through theservice provider mechanism.A version ofDefaultDetectorfor probabilistic mime detectors, which use statistical techniques to blend the results of differing underlying detectors when attempting to detect the type of a given file.Utility methods for content detection.Content type detector.Dummy detector that returns application/octet-stream for all documents.Character encoding detector.Context object that collects encoding detection results from base detectors.A single detector's contribution: its ranked list of candidates and its name.Caches the raw encoding-detection probe (the leading bytes read for detection) so that multiple detectors in a chain do not each re-read and re-tag-strip the same bytes.A charset detection result pairing aCharsetwith a confidence score and aEncodingResult.ResultTypeindicating the nature of the evidence.The nature of the evidence that produced this result.This runs the linux 'file' command against a file.High-byte decode-quality statistics shared by the charset detectors.Content type detection based on magic bytes, i.e. type-specific patterns near the beginning of the document input stream.Encoding detector that extracts a declared charset from Tika metadata without reading any bytes from the stream.Marker interface for encoding detectors that arbitrate among candidates collected by base detectors rather than detecting encoding directly from the stream.Content type detection based on the resource name.Dummy detector that always reportsapplication/octet-streamwithout even reading the given document stream.Deprecated.after 2.5.0 this functionality was moved to the CompositeDetectorAlways returns the charset passed in via the initializerConfiguration class for JSON deserialization.Content type detection of plain text documents.Utility class for computing a histogram of the bytes seen in a stream.Content type detection based on a content type hint.Utility class that uses aSAXParserto determine the namespace URI and local name of the root element of an XML file.Detector to identify zero length files as application/x-zerovalue
