public class AllocationExpression

extends NonLeaf

implements Expression

The AllocationExpression class represents an expression which allocates a new object with its constructor.
This expression is like:

     new String( "test" )
 

or:

     new String( "test" ){
             public void hoge(){ ... }
             ...
         }
 

The latter is supported from JDK 1.1, is called an anoymous class of the inner class.
