Constructor Detail

ConnectionImpl

protected ConnectionImpl(ManagedConnectionImpl _mc,
                         Connection _con,
                         long _key,

Method Detail

isPhysicallyClosed

public boolean isPhysicallyClosed()
                           throws SQLException

Returns:

true if connection is physically closed

Throws:

SQLException

setJonasInfo

public void setJonasInfo(org.ow2.jonas.resource.internal.cm.ManagedConnectionInfo _mci,
                         org.ow2.jonas.resource.internal.SQLManager _conman)

setUser

public void setUser()

invoke

public Object invoke(Object proxy,
                     Method method,
                     Object[] args)
              throws Throwable

Processes a method invocation on a proxy instance and returns the result. This method will be invoked on an invocation handler when a method is invoked on a proxy instance that it is associated with.

Specified by:

invoke in interface InvocationHandler

Parameters:

proxy - the proxy instance that the method was invoked on

method - the Method instance corresponding to the interface method invoked on the proxy instance.

args - an array of objects containing the values of the arguments passed in the method invocation on the proxy instance, or null if interface method takes no arguments.

Returns:

the value to return from the method invocation on the proxy instance.

Throws:

Throwable - the exception to throw from the method invocation on the proxy instance. The exception's type must be assignable either to any of the exception types declared in the throws clause of the interface method or to the unchecked exception types java.lang.RuntimeException or java.lang.Error. If a checked exception is thrown by this method that is not assignable to any of the exception types declared in the throws clause of the interface method, then an UndeclaredThrowableException containing the exception that was thrown by this method will be thrown by the method invocation on the proxy instance.

toArrayInt

public static int[] toArrayInt(Integer[] ints)

handleObjectMethods

protected Object handleObjectMethods(Method method,
                                     Object[] args)

Manages all methods of java.lang.Object class.

Parameters:

method - the Method instance corresponding to the interface method invoked on the proxy instance. The declaring class of the Method object will be the interface that the method was declared in, which may be a superinterface of the proxy interface that the proxy class inherits the method through.

args - an array of objects containing the values of the arguments passed in the method invocation on the proxy instance

Returns:

the value of the called method.

close

public void close(Object proxy)
           throws SQLException

Throws:

SQLException

isClosed

public boolean isClosed()
                 throws SQLException

Throws:

SQLException

setSignature

public void setSignature(long sig)

getKey

public long getKey()
