Class SQLite3Parser

java.lang.Object

org.apache.tika.parser.AbstractParser

org.apache.tika.parser.jdbc.SQLite3Parser

All Implemented Interfaces:

Serializable, Parser

public class SQLite3Parser
extends AbstractParser

This is the main class for parsing SQLite3 files. When parse(java.io.InputStream, org.xml.sax.ContentHandler, org.apache.tika.metadata.Metadata, org.apache.tika.parser.ParseContext) is called, this creates a new SQLite3DBParser.

Given potential conflicts of native libraries in web servers, users will need to add org.xerial's sqlite-jdbc jar to the class path for this parser to work. For development and testing, this jar is specified in tika-parsers' pom.xml, but it is currently set to "provided."

Note that this family of jdbc parsers is designed to treat each CLOB and each BLOB as an embedded document; i.e. it will recursively process documents that are stored in a sqlite db as "bytes".

If using a TikaInputStream, make sure to close it to delete the temp file that has to be created.

Checks to see if class is available for org.sqlite.JDBC.

If not, this class will return an EMPTY_SET for getSupportedTypes()

Method Detail

getSupportedTypes

public Set<MediaType> getSupportedTypes(ParseContext context)

Description copied from interface: Parser

Returns the set of media types supported by this parser when used with the given parse context.

Parameters:

context - parse context

Returns:

immutable set of media types

parse

public void parse(InputStream stream,
                  ContentHandler handler,
                  Metadata metadata,
                  ParseContext context)
           throws IOException,
                  SAXException,
                  TikaException

Description copied from interface: Parser

Parses a document stream into a sequence of XHTML SAX events. Fills in related document metadata in the given metadata object.

The given document stream is consumed but not closed by this method. The responsibility to close the stream remains on the caller.

Information about the parsing context can be passed in the context parameter. See the parser implementations for the kinds of context information they expect.

Parameters:

stream - the document stream (input)

handler - handler for the XHTML SAX events (output)

metadata - document metadata (input and output)

context - parse context

Throws:

IOException - if the document stream could not be read

SAXException - if the SAX events could not be processed

TikaException - if the document could not be parsed
