A unique key guarantees uniqueness on the defined columns within a table. There are some subtle differences between primary key and unique constraints. You can define only one primary key per table but there can be several unique keys. A primary key does not allow a null value in any of its columns whereas a unique key allows null values. As with the primary key constraint, there are several methods for creating a unique column constraint. This method uses the UNIQUE keyword inline with the column: create table dept(dept_id number, dept_desc varchar2(30) unique); If you want to explicitly name the constraint, use the CONSTRAINT keyword: create table dept(dept_id number, dept_desc varchar2(30) constraint dept_desc_uk1 unique); You can also add the tablespace information inline to be used for the associated unique index that is automatically created for unique constraints: create table dept(dept_id number, dept_desc varchar2(30) constraint dept_desc_uk1 unique using index tablespace prod_index);

to make the providers registered with the new API available to the clients of the old java.security.MessageDigest class. Another aspect to pay attention to is the merging vicious circle that can result in StackOverFlowErrors. The reasons are simple: one bridge registers itself as a provider in the old API and delegates to the new providers, while another provider is included among the new ones and delegates to the old providers. As demonstrated in Figure 15-6, this can easily create an endless loop that the code will walk until it exhausts the available stack space.

You can even use the + notation to chain delegates together; for example, you can create a delegate that will actually invoke the same method twice, as follows: StringOutputDelegate sayhellotwice; sayhellotwice = hello + hello; // invoke it Hello("mark"); This will repeat the output, as follows: Hello mark Hello mark Now that I ve touched on delegates, I ll cover how to integrate events into the equation. I ll elaborate on the concept of delegates with a more comprehensive example by still using a delegate but creating an event that fires the delegate. In this scenario, you ll create a new delegate that allows you to implement a change notification system. First, define the delegate as follows: public delegate void ChangedEventHandler(object sender, EventArgs e); Then define the following event that a client can use to inform you of a change: public event ChangedEventHandler changed; Then, in the client code, you can declare the following method that is used to fire the event:

Note When you create a unique key constraint, Oracle will also create a unique index with the same name as

Figure 15-6. Vicious flows of calls during runtime when double bridging This can be fixed in many ways. However, the most clueless fix is to use a thread local variable. Set it inside one bridge to indicate that one direction of bridging is in progress: private ThreadLocal<Boolean> searching = new ThreadLocal<Boolean>(); final boolean isSearching() { return Boolean.TRUE.equals(searching.get()); } @Override public synchronized Service getService(String type, String algorithm) { Boolean prev = searching.get(); try { searching.set(Boolean.TRUE); if ("MessageDigest".equals(type)) { Digest dig = Digest.getInstance(algorithm); if (dig != null) { return new ServiceImpl( dig, this, type, algorithm, "", Collections.<String>emptyList(), Collections.<String,String>emptyMap()); } } return null;
