Returns:

true If this implements the requested interface.

Throws:

SQLException - If the argument is not an interface.

Since:

JDBC 4.0

unwrap

public <T> T unwrap(Class<T> iface)
             throws SQLException

Since this class is not a wrapper, just check to see if this implements the requested interface.

Specified by:

unwrap in interface Wrapper

iface - Requested interface.

Returns:

this If this implements the requested interface.

Throws:

SQLException - If this does not implement the arg or the arg is not an interface.

createConnectionBuilder

public OracleConnectionBuilderImpl createConnectionBuilder()

Creates a new OracleConnectionBuilder instance

Specified by:

createConnectionBuilder in interface OracleDataSource

setSSLContext

public final void setSSLContext(SSLContext sslContext)

Description copied from interface: OracleCommonDataSource

Specifies a SSLContext to use as a factory for SSLEngine objects that carry out the TLS protocol.

The SSLContext must be initialized before establishing a connection to the data source. The certificates specified by that initialization will be used in place of any connection properties that would otherwise have specified certificates, such as key store and trust store property values.

Specifying a null value will clear any non-null value that may have been set previously, causing this data source to behave as if this method had never been called at all.

Specified by:

setSSLContext in interface OracleCommonDataSource

Parameters:

sslContext - An SSLContext to use as an SSLEngine factory.

setTokenSupplier

public final void setTokenSupplier(java.util.function.Supplier<? extends AccessToken> tokenSupplier)

Description copied from interface: OracleCommonDataSource

Sets a supplier function that generates an access token when creating a connection with this DataSource. The supplier function is invoked each time this DataSource creates a connection. Instances of AccessToken that are output by the supplier must represent a token type that is supported by Oracle Database for client authentication. The supplier must be thread safe.

It is invalid to configure this DataSource with both a token supplier and with a user name or password. If invocations of OracleCommonDataSource.setUser(String), OracleCommonDataSource.setPassword(String), OracleCommonDataSource.setConnectionProperties(java.util.Properties), or #setConnectionProperty(String, String) have configured this DataSource with a user name or password, and an invocation of this method has also configured a token supplier, then a SQLException indicating an invalid configuration is thrown when creating a connection with this datasource.

Note that AccessToken.createJsonWebTokenCache(Supplier) can be called to create a thread safe Supplier that caches tokens from a user defined Supplier.

Specified by:

setTokenSupplier in interface OracleCommonDataSource

Parameters:

tokenSupplier - Token supplying function. Not null.
