 com.sun.codemodel.JBlock
| JBlock | | final public class JBlock implements JGenerable,JStatement(Code) | | A block of Java code, which may contain statements and local declarations.
JBlock contains a large number of factory methods that creates new
statements/declarations. Those newly created statements/declarations are
inserted into the
JBlock.pos() "current position" . The position advances
one every time you add a new instruction.
