adds x to the top (left end) of this
aliases reference x
What does the Stack
updates this
method void push(T x) do?
ensures
this = <x> * #this
Removes and retursn the entry at the top (left end of
this)
What does the stack updates this
method T pop() do? requires this /= <>
ensures
#this = <pop> * this
Reports the length of this
What does the stack
ensures
method int length() do?
length = |this|
Returns the entry at the top (left end) of this
Aliases: reference returned by top
What does the stack requires:
method T top() do? this /= <>
ensures
<top> is prefix of this
replaces top of this with x, and returns the old top
aliases reference x
updates this
What does the stack
requires
method T replaceTop(T x)
this /= <>
do?
ensures:
<replaceTop> is prefix of #this and
this = <x> * #this[1, |#this|)
reverses ("flips") this
What does the stack updates this
method void flip() do? ensures
this = rev(#this)
