RE: [Php-java-bridge-users] Accessing enums

[Jost B. <jos...@ya...>]

Hi Mark,

the syntax for namspace access is different than the
syntax for property access.  For example if you have a
class

public interface php {
 public interface java {
  public class bridge {
   public enum JavaBridge = {UNITS, VOLUME, SCORE};
  }
 }
}

the JavaBridge would be accessed via: 

 $bridge = new
JavaClass('php$java$bridge$JavaBridge');
 echo $bridge->UNITS;

this is to avoid name clashes with the class:

 $bridge = new
JavaClass("php.java.bridge.JavaBridge");

The different syntax makes sense, an I hope the PHP6
developers don't make the same mistake that sun made;
if you compile and place the above php.class into your
classpath, then no java developer can access the class
php.java.bridge.JavaBridge anymore because the java
compiler automatically rewrites the syntax
php.java.bridge.JavaBridge into
php$java$bridge$JavaBridge and stores this into the
.class file.

However, the real fun begins if you compile and place
the following java.class into your classpath:

public interface java {
 public class lang {
  public enum String = {one, two};
 }
}

After that a new java.lang.String() will return the
above enum. -- But I guess this problem is caught by
the java bytecode verifier...
