  org.logicalcobwebs.proxool.ProxyDatabaseMetaData

All Implemented Interfaces:

Callback, MethodInterceptor

 class ProxyDatabaseMetaData
extends java.lang.Object
implements MethodInterceptor

Delegates to a normal Coonection for everything but the close() method (when it puts itself back into the pool instead).

Constructor Detail

ProxyDatabaseMetaData

public ProxyDatabaseMetaData(java.sql.DatabaseMetaData databaseMetaData,
                             java.sql.Connection wrappedConnection)

Parameters:

databaseMetaData - the meta data we use to delegate all calls to (except getConnection())

wrappedConnection - the connection we return if asked for the connection

Method Detail

intercept

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

Description copied from interface: MethodInterceptor

All generated proxied methods call this method instead of the original method. The original method may either be invoked by normal reflection using the Method object, or by using the MethodProxy (faster).

Specified by:

intercept in interface MethodInterceptor

Parameters:

proxy - "this", the enhanced object

method - intercepted Method

args - argument array; primitive types are wrapped

methodProxy - 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:

MethodProxy

equals

public boolean equals(java.lang.Object obj)

Whether the underlying databaseMetaData are equal

Overrides:

equals in class java.lang.Object

Parameters:

obj - the object (probably another databaseMetaData) that we are being compared to

Returns:

whether they are the same

getConnection

public java.sql.Connection getConnection()

We don't want to ask the DatabaseMetaData object for the connection or we will get the delegate instead of the Proxool one.

See Also:

DatabaseMetaData.getConnection()

getDatabaseMetaData

protected java.sql.DatabaseMetaData getDatabaseMetaData()

Get the DatabaseMetaData from the connection

Returns:

databaseMetaData

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

Object.toString()
