Examples of com.sun.codemodel.JBlock

com.sun.codemodel.JBlock
A block of Java code, which may contain statements and local declarations.
{@link JBlock} contains a large number of factory methods that creates newstatements/declarations. Those newly created statements/declarations are inserted into the {@link #pos() "current position"}. The position advances one every time you add a new instruction.
