public class IfStmt
extends Statement
implements NodeWithCondition<IfStmt>

An if-then-else statement. The else is optional.
In if(a==5) hurray() else boo(); the condition is a==5, hurray() is the thenStmt, and boo() is the elseStmt.

A - the type the user argument passed to the visitor

Parameters:

v - the visitor implementation

arg - the argument passed to the visitor (of type A)

Returns:

the result of the visit (of type R)

accept

public <A> void accept(VoidVisitor<A> v,
 A arg)

Description copied from interface: Visitable

Accept method for visitor support.

Specified by:

accept in interface Visitable

Type Parameters:

A - the type the argument passed for the visitor

Parameters:

v - the visitor implementation

arg - any value relevant for the visitor (of type A)
