Method Detail

jjtAccept

public Object jjtAccept(IJevaVisitor visitor,
                        Object data)

Description copied from interface: IJevaNode

Accept a visitor. For visitor design pattern: jjtAccept must simply

  return visitor.visit(this, data);  

which dispatches on the type of this to appropriate method of visitor

Overrides:

jjtAccept in class JevaNode

getLabel

public String getLabel()

default label is ""

verifyTypes

public IEnv verifyTypes(IEnv env)
                 throws VerifyingException

Description copied from interface: IStatementNode

Verify types within this statement; don't call this directly, use EvalMethods.verifyTypes(IStatementNode, IEnv). Builds env without evaluating anything with side effects, for the purpose of verifying types of later statements. May be used by preprocessors which must find the type of an expression in order to assign it to a new variable.

Specified by:

verifyTypes in interface IStatementNode

Tags copied from interface: IStatementNode

Parameters:

env - environment of names bindings.

Returns:

env or possibly extended env

Throws:

VerifyingException - if statement is illegal

See Also:

EvalMethods.verifyTypes(IStatementNode, IEnv)

eval

public IEnv eval(IEnv env)
          throws ContinueException

Description copied from interface: IStatementNode

Evaluate this Statement; don't call this directly, use EvalMethods.eval(IStatementNode, IEnv) Every statement needs to implement an eval method.

Specified by:

eval in interface IStatementNode

Tags copied from interface: IStatementNode

Parameters:

env - environment of names bindings.

Returns:

env or possibly extended env

Throws:

AbruptCompletionException - if abruptly completed with return, throw, break, or continue.
