jjtAccept

public Object jjtAccept(IJevaVisitor visitor,
                        Object data)

Overrides:

jjtAccept in class JevaNode

getDeclaration

public final IDeclarationNode getDeclaration(int i)

getNumDeclarations

public final int getNumDeclarations()

scanDeclarations

public IEnv scanDeclarations(IEnv env)
                      throws VerifyingException

computeTypeSignatures

public void computeTypeSignatures(IEnv env)
                           throws VerifyingException

verifyTypes

public IEnv verifyTypes(IEnv env)
                 throws VerifyingException

eval

public void eval(String[] arguments,
                 IEnv env)
          throws ClassNotFoundException,
                 ThrowException

Eval finds the public static void main(String[]) method of the public class (there should be only one) and runs it.

Throws:

ClassNotFoundException - if no public class with main method found.

ThrowException - if method throws exception.
