Constructor.

Method Detail

acceptsURL

public boolean acceptsURL(String url)
                   throws SQLException
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.

Awake driver requires an URL which is an http url in the format:
http(s)://<server-name:port>/<Awake SQL Servlet path>

Example:
http://www.acme.com/AwakeSqlManager

Specified by:
acceptsURL in interface Driver
Parameters:
url - the URL of the database
Returns:
true if this driver understands the given URL; false otherwise
Throws:
SQLException - if a database access error occurs

connect

public Connection connect(String url,
                          Properties info)
                   throws SQLException
Attempts to make a database connection to the given URL. The Awake driver will return "null" if it realizes it is the wrong kind of driver to connect to the given URL. acceptsURL(java.lang.String) will return null.

The Awake driver will throwSQLException 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. 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. 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

getMajorVersion

public int getMajorVersion()
Retrieves this driver's major version number.

Specified by:
getMajorVersion in interface Driver
Returns:
this driver's major version number

getMinorVersion

public int getMinorVersion()
Gets the driver's minor version number.

Specified by:
getMinorVersion in interface Driver
Returns:
this driver's minor version number

getParentLogger

public Logger getParentLogger()
                       throws SQLFeatureNotSupportedException
Return the parent Logger of all the Loggers used by this driver. This should be the Logger farthest from the root Logger that is still an ancestor of all of the Loggers used by this driver. Configuring this Logger will affect all of the log messages generated by the driver. In the worst case, this may be the root Logger.

Returns:
the parent Logger for this driver
Throws:
SQLFeatureNotSupportedException - if the driver does not use java.util.logging.
Since:
1.7

getPropertyInfo

public DriverPropertyInfo[] getPropertyInfo(String url,
                                            Properties info)
                                     throws SQLException
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.
Throws:
SQLException - if a database access error occurs

jdbcCompliant

public boolean jdbcCompliant()
Reports whether this driver is a genuine JDBC CompliantTM 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.

Because Awake driver is not a a genuine JDBC CompliantTM driver, method returns false

Specified by:
jdbcCompliant in interface Driver
Returns:
false
