Class DBContext

java.lang.Object
org.apache.velocity.context.AbstractContext
org.apache.velocity.example.DBContext
All Implemented Interfaces:
org.apache.velocity.context.Context, org.apache.velocity.context.InternalEventContext
public class DBContext extends org.apache.velocity.context.AbstractContext
Example context impl that uses a database to store stuff :) yes, this is silly expects a mysql db test with table CREATE TABLE contextstore ( k varchar(100), val blob ); very fragile, crappy code.... just a demo!

    • internalGet

      public Object internalGet(String key)
      retrieves a serialized object from the db and returns the living instance to the caller.
      Specified by:
      internalGet in class org.apache.velocity.context.AbstractContext

    • internalPut

      public Object internalPut(String key, Object value)
      Serializes and stores an object in the database. This is really a hokey way to do it, and will cause problems. The right way is to use a prepared statement...

      internalPut in class org.apache.velocity.context.AbstractContext

    • internalContainsKey

      public boolean internalContainsKey(String key)
      Not implementing. Not required for Velocity core operation, so not bothering. As we say above : "very fragile, crappy code..."
