Class \Prado\Collections\TStack

TStack class

TStack implements a stack.

The typical stack operations are implemented, which include push(), pop() and peek(). In addition, contains() can be used to check if an item is contained in the stack. To obtain the number of the items in the stack, check the \Prado\Collections\getCount property.

Items in the stack may be traversed using foreach as follows,

foreach($stack as $item) ...

`public`	`contains(mixed $item) : bool`
`public`	`copyFrom(mixed $data) : mixed` Copies iterable data into the stack. Note, existing data in the list will be cleared first.
`public`	`count() : int` Returns the number of items in the stack. This method is required by \Countable interface.
`public`	`getCount() : int`
`public`	`getIterator() : Iterator` Returns an iterator for traversing the items in the stack. This method is required by the interface \IteratorAggregate.
`public`	`peek() : mixed` Returns the item at the top of the stack. Unlike pop(), this method does not remove the item from the stack.
`public`	`pop() : mixed` Pops up the item at the top of the stack.
