Imports

Class that resets the abandoned timer on any activity on the Connection or any successful query executions. This interceptor is useful for when you have a org.apache.tomcat.jdbc.pool.PoolConfiguration#setRemoveAbandonedTimeout(int) that is fairly low, and you want to reset the abandoned time each time any operation on the connection is performed This is useful for batch processing programs that use connections for extensive amount of times.

Arguments of primitive types are wrapped in instances of the appropriate primitive wrapper class, such as java.lang.Integer or java.lang.Boolean.

public void closeInvoked()

Implements abstract org.apache.tomcat.jdbc.pool.interceptor.AbstractCreateStatementInterceptor.closeInvoked.

Method invoked when the operation java.sql.Connection#close() is invoked.

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

Overrides org.apache.tomcat.jdbc.pool.interceptor.AbstractCreateStatementInterceptor.invoke.

Implements java.lang.reflect.InvocationHandler.invoke.

Doc from org.apache.tomcat.jdbc.pool.JdbcInterceptor.invoke.

Gets invoked each time an operation on java.sql.Connection is invoked. 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.

Parameters
proxy:Object

Doc from java.lang.reflect.InvocationHandler.invoke.

the proxy instance that the method was invoked on

method:Method

Doc from java.lang.reflect.InvocationHandler.invoke.

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:Object[]

Doc from java.lang.reflect.InvocationHandler.invoke.

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. Arguments of primitive types are wrapped in instances of the appropriate primitive wrapper class, such as java.lang.Integer or java.lang.Boolean.

Returns:Object

Doc from java.lang.reflect.InvocationHandler.invoke.

the value to return from the method invocation on the proxy instance. If the declared return type of the interface method is a primitive type, then the value returned by this method must be an instance of the corresponding primitive wrapper class; otherwise, it must be a type assignable to the declared return type. If the value returned by this method is null and the interface method's return type is primitive, then a NullPointerException will be thrown by the method invocation on the proxy instance. If the value returned by this method is otherwise not compatible with the interface method's declared return type as described above, a ClassCastException will be thrown by the method invocation on the proxy instance.

Annotations
@Override
Exceptions
Throwable:

Doc from java.lang.reflect.InvocationHandler.invoke.

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.
