Examples of org.apache.tomcat.jdbc.pool.JdbcInterceptor

org.apache.tomcat.jdbc.pool.JdbcInterceptor
Abstract class that is to be extended for implementations of interceptors. Everytime an operation is called on the {@link java.sql.Connection} object the {@link #invoke(Object,Method,Object[])} method on the interceptor will be called.Interceptors are useful to change or improve behavior of the connection pool.
Interceptors can receive a set of properties. Each sub class is responsible for parsing the properties during runtime when they are needed or simply override the {@link #setProperties(Map)} method. Properties arrive in a key-value pair of Strings as they were received through the configuration. This method is called once per cached connection object when the object is first configured. @author Filip Hanik @version 1.0
