isWrapperForback to summary
public boolean isWrapperFor(Class<?> iface) throws SQLException

Implements java.sql.Wrapper.isWrapperFor.

Doc from java.sql.Wrapper.isWrapperFor.

Returns true if this either implements the interface argument or is directly or indirectly a wrapper for an object that does. Returns false otherwise. If this implements the interface then return true, else if this is a wrapper then return the result of recursively calling isWrapperFor on the wrapped object. If this does not implement the interface and is not a wrapper, return false. This method should be implemented as a low-cost operation compared to unwrap so that callers can use this method to avoid expensive unwrap calls that may fail. If this method returns true then calling unwrap with the same argument should succeed.

Parameters
iface:Class<?>

a Class defining an interface.

Returns:boolean

true if this implements the interface or directly or indirectly wraps an object that does.

Annotations
@Override
Exceptions
SQLException:
if an error occurs while determining whether this is a wrapper for an object with the given interface.

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

Implements java.sql.Wrapper.unwrap.

Doc from java.sql.Wrapper.unwrap.

Returns an object that implements the given interface to allow access to non-standard methods, or standard methods not exposed by the proxy. If the receiver implements the interface then the result is the receiver or a proxy for the receiver. If the receiver is a wrapper and the wrapped object implements the interface then the result is the wrapped object or a proxy for the wrapped object. Otherwise return the the result of calling unwrap recursively on the wrapped object or a proxy for that result. If the receiver is not a wrapper and does not implement the interface, then an SQLException is thrown.

Parameters
<T>
the type of the class modeled by this Class object
iface:Class<T>

A Class defining an interface that the result must implement.

Returns:T

an object that implements the interface. May be a proxy for the actual implementing object.

Annotations
@Override
Exceptions
SQLException:
If no object found that implements the interface
