- Constructor Detail
  - LongStack
```
public LongStack()
```
    New instance with sane defaults.
  - LongStack
```
public LongStack(int expectedElements)
```
    New instance with sane defaults.
    
    Parameters:
    
    expectedElements - The expected number of elements guaranteed not to cause buffer expansion (inclusive).
  - LongStack
```
public LongStack(int expectedElements,
                 ArraySizingStrategy resizer)
```
    New instance with sane defaults.
    
    Parameters:
    
    expectedElements - The expected number of elements guaranteed not to cause buffer expansion (inclusive).
    
    resizer - Underlying buffer sizing strategy.
  - LongStack
```
public LongStack(LongContainer container)
```
    Create a stack by pushing all elements of another container to it.
- Method Detail
  - push
```
public void push(long e1)
```
    Adds one long to the stack.
  - push
```
public void push(long e1,
                 long e2)
```
    Adds two longs to the stack.
  - push
```
public void push(long e1,
                 long e2,
                 long e3)
```
    Adds three longs to the stack.
  - push
```
public void push(long e1,
                 long e2,
                 long e3,
                 long e4)
```
    Adds four longs to the stack.
  - push
```
public void push(long[] elements,
                 int start,
                 int len)
```
    Add a range of array elements to the stack.
  - push
```
public final void push(long... elements)
```
    Vararg-signature method for pushing elements at the top of the stack.
    This method is handy, but costly if used in tight loops (anonymous array passing)
  - pushAll
```
public int pushAll(LongContainer container)
```
    Pushes all elements from another container to the top of the stack.
  - pushAll
```
public int pushAll(Iterable<? extends LongCursor> iterable)
```
    Pushes all elements from another iterable to the top of the stack.
  - discard
```
public void discard(int count)
```
    Discard an arbitrary number of elements from the top of the stack.
  - discard
```
public void discard()
```
    Discard the top element from the stack.
  - pop
```
public long pop()
```
    Remove the top element from the stack and return it.
  - peek
```
public long peek()
```
    Peek at the top element on the stack.
  - from
```
public static LongStack from(long... elements)
```
    Create a stack by pushing a variable number of arguments to it.
  - clone
```
public LongStack clone()
```
    Clone this object. The returned clone will reuse the same hash function and array resizing strategy.
  - removeAll
```
public int removeAll(LongLookupContainer c)
```
    Default implementation uses a predicate for removal.
    
    Specified by:
    
    removeAll in interface LongCollection
    
    Returns:
    
    Returns the number of removed elements.
  - retainAll
```
public int retainAll(LongLookupContainer c)
```
    Default implementation uses a predicate for retaining.
    
    Specified by:
    
    retainAll in interface LongCollection
    
    Returns:
    
    Returns the number of removed elements.
  - retainAll
```
public int retainAll(LongPredicate predicate)
```
    Default implementation redirects to LongCollection.removeAll(LongPredicate) and negates the predicate.
    
    Specified by:
    
    retainAll in interface LongCollection
    
    Returns:
    
    Returns the number of removed elements.
  - toString
```
public String toString()
```
    Convert the contents of this container to a human-friendly string.
