The basic use of Chronus.
Once the chronus.jar
has been included in your classpath you are able
to use it the same as you would any other map-implementing class.
Chronus functions like a persistant hashtable!.
Our first look
at Chronus involves us saving a simple string to the database and
Here is the code:
//This comes in at the
beginning of your source file
//And this goes into
Chronus db = new Chronus();
db.put("Key", "This is a test"); //First the
key, then the parameter.
The first thing
we did is create a Chronus instance, calling up the constructor
without any arguments informs chronus that the global database
(stored in the /Database folder and called chronus) is used. Next
we inserted a key-value pair into the database, the key is the identifier
for the object, and the value is the actual data. The key is then
given as a parameter in get("Key") in order to load the
This is all
fine and dandy, but what if I need to store a custom object?
All custom objects
stored in Chronus have to implement the Serializable interface, this
does not actually involve writing any complex methods, or any code
at all for that matter, but it is neccesary to tell Chronus that
the object can be broken down into binary data.
So the declaration
of a custom object will look a little like this:
class customObject implements
The saving and loading
of the custom object is exactly the same as in the previous section.
