Constructor Summary

WrappedConnection(ProxyConnection proxyConnection)
Construct this wrapper around the proxy connection

Method Summary

boolean	equals(java.lang.Object obj) If the object passed to this method is actually a proxied version of this class then compare the real class with this one.
java.lang.String	getAlias() Get the alias of the connection pool this connection belongs to
long	getId() The ID for the encapsulated ProxyConnection.
ProxyConnection	getProxyConnection() Get the encapsulated proxy connection

Constructor Detail

WrappedConnection

public WrappedConnection(ProxyConnection proxyConnection)

Construct this wrapper around the proxy connection

Parameters:

proxyConnection - to wrap

Method Detail

getProxyConnection

public ProxyConnection getProxyConnection()

Get the encapsulated proxy connection

Returns:

the proxy connection

intercept

public java.lang.Object intercept(java.lang.Object obj,
                                  java.lang.reflect.Method method,
                                  java.lang.Object[] args,
                                  org.logicalcobwebs.cglib.proxy.MethodProxy proxy)
                           throws java.lang.Throwable

Delegates to invoke

Specified by:

intercept in interface org.logicalcobwebs.cglib.proxy.MethodInterceptor

Parameters:

obj - "this", the enhanced object

method - intercepted Method

args - argument array; primitive types are wrapped

proxy - used to invoke super (non-intercepted method); may be called as many times as needed

Returns:

any value compatible with the signature of the proxied method. Method returning void will ignore this value.

Throws:

java.lang.Throwable - any exception may be thrown; if so, super method will not be invoked

See Also:

MethodInterceptor.intercept(java.lang.Object, java.lang.reflect.Method, java.lang.Object[], org.logicalcobwebs.cglib.proxy.MethodProxy)

invoke

public java.lang.Object invoke(java.lang.Object proxy,
                               java.lang.reflect.Method method,
                               java.lang.Object[] args)
                        throws java.lang.Throwable

Delegates all operations to the encapsulated ProxyConnection except for:

• close()
• equals()
• hashCode()
• isClosed()
• getMetaData()
• finalize()

It also spots mutators and remembers that the property has been changed so that it can be reset. And any statements that are returned are remembered so that we can track whether all statements have been closed properly when the connection is returned to the pool.

Throws:

java.lang.Throwable

See Also:

InvocationHandler.invoke(java.lang.Object, java.lang.reflect.Method, java.lang.Object[])

getId

public long getId()

The ID for the encapsulated ProxyConnection. This will still return the correct value after the connection is closed.

Returns:

the ID

getAlias

public java.lang.String getAlias()

Get the alias of the connection pool this connection belongs to

Returns:

alias

equals

public boolean equals(java.lang.Object obj)

If the object passed to this method is actually a proxied version of this class then compare the real class with this one.

Overrides:

equals in class java.lang.Object

Parameters:

obj - the object to compare

Returns:

true if the object is a proxy of "this"

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

See Also:

Object.toString()
