Class MonetDriver

java.lang.Object

nl.cwi.monetdb.jdbc.MonetDriver

All Implemented Interfaces:

Driver

public final class MonetDriver
extends Object
implements Driver

A Driver suitable for the MonetDB database. This driver will be used by the DriverManager to determine if an URL is to be handled by this driver, and if it does, then this driver will supply a Connection suitable for MonetDB. This class has no explicit constructor, the default constructor generated by the Java compiler will be sufficient since nothing has to be set in order to use this driver. This Driver supports MonetDB database URLs. MonetDB URLs are defined as: jdbc:monetdb://<host>[:<port>]/<database> where [:<port>] denotes that a port is optional. If not given the default (50000) will be used.

Constructor Detail

MonetDriver

public MonetDriver()

Method Detail

acceptsURL

public boolean acceptsURL(String url)

Retrieves whether the driver thinks that it can open a connection to the given URL. Typically drivers will return true if they understand the subprotocol specified in the URL and false if they do not.

Specified by:

acceptsURL in interface Driver

Parameters:

url - the URL of the database

Returns:

true if this driver understands the given URL; false otherwise

getMajorVersion

public int getMajorVersion()

Retrieves the driver's major version number. Initially this should be 1.

Specified by:

getMajorVersion in interface Driver

Returns:

this driver's major version number

getMinorVersion

public int getMinorVersion()

Gets the driver's minor version number. Initially this should be 0.

Specified by:

getMinorVersion in interface Driver

Returns:

this driver's minor version number

getPropertyInfo

public DriverPropertyInfo[] getPropertyInfo(String url,
                                            Properties info)

Gets information about the possible properties for this driver. The getPropertyInfo method is intended to allow a generic GUI tool to discover what properties it should prompt a human for in order to get enough information to connect to a database. Note that depending on the values the human has supplied so far, additional values may become necessary, so it may be necessary to iterate though several calls to the getPropertyInfo method.

Specified by:

getPropertyInfo in interface Driver

Parameters:

url - the URL of the database to which to connect

info - a proposed list of tag/value pairs that will be sent on connect open

Returns:

an array of DriverPropertyInfo objects describing possible properties. This array may be an empty array if no properties are required.

jdbcCompliant

public boolean jdbcCompliant()

Reports whether this driver is a genuine JDBC Compliant&tm; driver. A driver may only report true here if it passes the JDBC compliance tests; otherwise it is required to return false. JDBC compliance requires full support for the JDBC API and full support for SQL 92 Entry Level. It is expected that JDBC compliant drivers will be available for all the major commercial databases. This method is not intended to encourage the development of non-JDBC compliant drivers, but is a recognition of the fact that some vendors are interested in using the JDBC API and framework for lightweight databases that do not support full database functionality, or for special databases such as document information retrieval where a SQL implementation may not be feasible.

Specified by:

jdbcCompliant in interface Driver

Returns:

true if this driver is JDBC Compliant; false otherwise

getJavaType

public static int getJavaType(String type)

Returns the java.sql.Types equivalent of the given MonetDB type.

Parameters:

type - the type as used by MonetDB

Returns:

the matching java.sql.Types constant or java.sql.Types.OTHER if nothing matched on the given string

getDriverVersion

public static String getDriverVersion()

Returns a touched up identifying version string of this driver.

Returns:

the version string

getDriverMajorVersion

public static int getDriverMajorVersion()

getDriverMinorVersion

public static int getDriverMinorVersion()

getParentLogger

public Logger getParentLogger()
                       throws SQLFeatureNotSupportedException

Return the parent Logger of all the Loggers used by this data source. This should be the Logger farthest from the root Logger that is still an ancestor of all of the Loggers used by this data source. Configuring this Logger will affect all of the log messages generated by the data source. In the worst case, this may be the root Logger.

Specified by:

getParentLogger in interface Driver

Returns:

the parent Logger for this data source

Throws:

SQLFeatureNotSupportedException - if the data source does not use java.util.logging

connect

public Connection connect(String url,
                          Properties info)
                   throws SQLException

Attempts to make a database connection to the given URL. The driver should return "null" if it realizes it is the wrong kind of driver to connect to the given URL. This will be common, as when the JDBC driver manager is asked to connect to a given URL it passes the URL to each loaded driver in turn. The driver should throw an SQLException if it is the right driver to connect to the given URL but has trouble connecting to the database. The java.util.Properties argument can be used to pass arbitrary string tag/value pairs as connection arguments. Normally at least "user" and "password" properties should be included in the Properties object.

Specified by:

connect in interface Driver

Parameters:

url - the URL of the database to which to connect

info - a list of arbitrary string tag/value pairs as connection arguments. Normally at least a "user" and "password" property should be included

Returns:

a Connection object that represents a connection to the URL

Throws:

SQLException - if a database access error occurs
