DriverWrapper

protected DriverWrapper()

Method Details

toString

public String toString()

Overrides:

toString in class Object

getUrlPrefix

protected abstract String getUrlPrefix()

Gets the JDBC prefix used for this driver wrapper. This will be inserted after "jdbc:" in the wrapped driver URL. For example, "jdbc:prefix:postgresql://host/database"

newConnectionWrapper

protected ConnectionWrapperImpl newConnectionWrapper(Connection connection)

Creates a new ConnectionWrapperImpl.

See Also:

• wrapConnection(java.sql.Connection)

wrapConnection

protected ConnectionWrapperImpl wrapConnection(Connection connection)

Wraps a Connection, if not already wrapped by this wrapper.

See Also:

• newConnectionWrapper(java.sql.Connection)

toWrappedUrl

protected String toWrappedUrl(String wrapperUrl)

Gets the JDBC URL used by the wrapped driver. This removes the prefix from the URL.

Returns:

The modified URL or null when prefix not found in the URL.

toWrapperUrl

protected String toWrapperUrl(String wrappedUrl)
                       throws SQLException

Gets the JDBC URL used by the wrapper driver. This adds the prefix to the URL.

Returns:

The modified URL, with prefix in the URL.

Throws:

SQLException - When the wrapped URL does not begin with JDBC_SCHEMA

See Also:

• DatabaseMetaDataWrapper.getURL()

getDriverName

protected String getDriverName(String wrappedName)

Gets the driver name for the given wrapped-driver's name.

This default implementation prefixes the wrapped-driver's name with getUrlPrefix() + ':'.

See Also:

• DatabaseMetaDataWrapper.getDriverName()

getDriverVersion

protected String getDriverVersion(String wrappedVersion)

Gets the driver version for the given wrapped-driver's version.

This default implementation prefixes the wrapped-driver's version with getVersion() + ':'.

See Also:

• DatabaseMetaDataWrapper.getDriverVersion()
• getVersion()

getDriverMajorVersion

protected int getDriverMajorVersion(int wrappedMajor)

Gets the driver major version for the given wrapped-driver's major version.

This default implementation returns getMajorVersion().

See Also:

• DatabaseMetaDataWrapper.getDriverMajorVersion()

getDriverMinorVersion

protected int getDriverMinorVersion(int wrappedMinor)

Gets the driver minor version for the given wrapped-driver's minor version.

This default implementation returns getMinorVersion().

See Also:

• DatabaseMetaDataWrapper.getDriverMinorVersion()
