Method Details

close

public void close()
           throws OntoDriverException

Description copied from interface: Closeable

Closes this resource releasing any sub-resources it holds.

After closing the resource is not usable any more and calling methods on it (except close and isOpen) will result in IllegalStateException.

Calling close on already closed resource does nothing.

Specified by:

close in interface Closeable

Throws:

OntoDriverException - If an ontology access error occurs.

isOpen

public boolean isOpen()

Description copied from interface: Closeable

Retrieves status of this resource.

Specified by:

isOpen in interface Closeable

Returns:

true if the resource is open, false otherwise

unwrap

public <T> T unwrap(Class<T> cls)
             throws OntoDriverException

Description copied from interface: Wrapper

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 OntoDriverException is thrown.

Specified by:

unwrap in interface Wrapper

Type Parameters:

T - The type of the class modeled by this Class object

Parameters:

cls - The type of the required result

Returns:

An object implementing the interface

Throws:

OntoDriverException - If no matching object is found
