public class JNDConstructorDeclaration

extends JevaNode

implements IClassBodyDeclaration, JevaParserConstants

Method Detail

jjtAccept

public Object jjtAccept(IJevaVisitor visitor,
                        Object data)

Overrides:

jjtAccept in class JevaNode

getConstructor

public InterpretedConstructor getConstructor()
                                      throws IllegalStateException

getParametersNode

public JNFormalParameterList getParametersNode()

getNumStatementNodes

public int getNumStatementNodes()

getStatementNode

public IStatementNode getStatementNode(int i)

getFirstStatementIndex

public int getFirstStatementIndex()

return index at which first statement can be inserted

computeConstructor

protected InterpretedConstructor computeConstructor(IEnv env)
                                             throws VerifyingException

Create constructor. Also initializes this node, adding default explicit constructor invocation "super();" if missing.

verifyTypes

public IEnv verifyTypes(IEnv staticEnv,
                        IEnv objectEnv)
                 throws VerifyingException

evalExplicitConstructorCallParameter

public Object evalExplicitConstructorCallParameter(int paramIndex,
                                                   Object[] arguments,
                                                   IEnv classEnv)
                                            throws ThrowException

evalConstructorBody

public void evalConstructorBody(Object target,
                                Object[] arguments,
                                IEnv classEnv)
                         throws ThrowException

eval constructor body AFTER explicit constructor invocation
