Method Details

visitStack

public static <T> void visitStack(List<T> stack,
 Consumer<? super T> visitor)

Visits elements on a stack, popping one off from the end each time. Visitor function MAY edit the stack. Will terminate when stack is empty. IMPORTANT: O(1) usage of JVM stack, may be necessary to use a function like this when visiting deeply nested trees in CVM code.

Type Parameters:

T - Type of element to visit

Parameters:

stack - Stack of values to visit, must be a mutable List

visitor - Visitor function to call for each stack element.

visitStackMaybePopping

public static <T> void visitStackMaybePopping(List<T> stack,
 Predicate<? super T> visitor)

Visits elements on a stack, the element if predicate returns true. Predicate function MAY add to the stack. Will terminate when stack is empty. IMPORTANT: O(1) usage of JVM stack, may be necessary to use a function like this when visiting deeply nested trees in CVM code.

Type Parameters:

T - Type of element to visit

Parameters:

stack - Stack of values to visit, must be a mutable List

visitor - Visitor function to call for each stack element.
