isWrapperFor	back 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 boolean isWrapperFor(Class<?> iface) throws SQLException

Implements java.sql.Wrapper.isWrapperFor.

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.

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.

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

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.
