public SQLite3DBParser()

Method Details

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.

Specified by:

getSupportedTypes in interface Parser

Overrides:

getSupportedTypes in class AbstractDBParser

Parameters:

context - context

Returns:

null (always)

getConnection

protected Connection getConnection(InputStream stream,
 Metadata metadata,
 ParseContext context)
                            throws IOException

Description copied from class: AbstractDBParser

Override this for special configuration of the connection, such as limiting the number of rows to be held in memory.

Overrides:

getConnection in class AbstractDBParser

Parameters:

stream - stream to use

metadata - metadata that could be used in parameterizing the connection

context - parsecontext that could be used in parameterizing the connection

Returns:

connection

Throws:

IOException

getConnectionString

protected String getConnectionString(InputStream is,
 Metadata metadata,
 ParseContext context)
                              throws IOException

Description copied from class: AbstractDBParser

Implement for db specific connection information, e.g. "jdbc:sqlite:/docs/mydb.db"

Include any optimization settings, user name, password, etc.

Specified by:

getConnectionString in class AbstractDBParser

Parameters:

is - stream for processing

metadata - metadata might be useful in determining connection info

context - context to use to help create connectionString

Returns:

connection string to be used by AbstractDBParser.getConnection(java.io.InputStream, org.apache.tika.metadata.Metadata, org.apache.tika.parser.ParseContext).

Throws:

IOException

close

public void close()
           throws SQLException,
IOException

Description copied from class: AbstractDBParser

Override this for any special handling of closing the connection.

Overrides:

close in class AbstractDBParser

Throws:

SQLException

IOException

getJDBCClassName

Returns the names of the tables to process

Specified by:

getTableNames in class AbstractDBParser

Parameters:

connection - Connection to use to make the sql call(s) to get the names of the tables

metadata - Metadata to use (potentially) in decision about which tables to extract

context - ParseContext to use (potentially) in decision about which tables to extract

Returns:

Throws:

SQLException
