isWrapperFor back to summary

isWrapperFor	back to summary
public synchronized boolean isWrapperFor(Class<T> a) 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 a:Class<T> a Class defining an interface. Returns:boolean true if this implements the interface or directly or indirectly wraps an object that does. Exceptions SQLException: if an error occurs while determining whether this is a wrapper for an object with the given interface.

public synchronized boolean isWrapperFor(Class<T> a) throws SQLException

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

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 a:Class<T> A Class defining an interface that the result must implement.
