- 方法详细资料
  - push
```
void push(T newCurrent)
```
    Push the new element on the top of the stack
  - pop
```
T pop()
```
    Pop (remove and return) the current element off the stack
  - getCurrent
```
T getCurrent()
```
    The element currently at the top of the stack
  - getPrevious
```
T getPrevious()
```
    The element previously at the top of the stack before the current one
  - depth
```
int depth()
```
    How many elements are currently on the stack?
  - isEmpty
```
boolean isEmpty()
```
    Are there no elements currently in the stack?
  - clear
```
void clear()
```
    Remove all elements from the stack
  - visitCurrentFirst
```
void visitCurrentFirst(Consumer<T> action)
```
    Visit all elements in the stack, starting with the current and working back
  - findCurrentFirst
```
<X> X findCurrentFirst(Function<T,X> action)
```
    Find an element on the stack and return a value. The first non-null element returned from `action` stops the iteration and is returned from here
