- Constructor Detail
  - DoubleStack
```
public DoubleStack()
```
    New instance with sane defaults.
  - DoubleStack
```
public DoubleStack(int expectedElements)
```
    New instance with sane defaults.
    
    Parameters:
    
    expectedElements - The expected number of elements guaranteed not to cause buffer expansion (inclusive).
  - DoubleStack
```
public DoubleStack(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.
  - DoubleStack
```
public DoubleStack(DoubleContainer container)
```
    Create a stack by pushing all elements of another container to it.
- Method Detail
  - push
```
public void push(double e1)
```
    Adds one double to the stack.
  - push
```
public void push(double e1,
                 double e2)
```
    Adds two doubles to the stack.
  - push
```
public void push(double e1,
                 double e2,
                 double e3)
```
    Adds three doubles to the stack.
  - push
```
public void push(double e1,
                 double e2,
                 double e3,
                 double e4)
```
    Adds four doubles to the stack.
  - push
```
public void push(double[] elements,
                 int start,
                 int len)
```
    Add a range of array elements to the stack.
  - push
```
public final void push(double... 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(DoubleContainer container)
```
    Pushes all elements from another container to the top of the stack.
  - pushAll
```
public int pushAll(java.lang.Iterable<? extends DoubleCursor> 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 double pop()
```
    Remove the top element from the stack and return it.
  - peek
```
public double peek()
```
    Peek at the top element on the stack.
  - from
```
public static DoubleStack from(double... elements)
```
    Create a stack by pushing a variable number of arguments to it.
  - clone
```
public DoubleStack clone()
```
    Clone this object. The returned clone will reuse the same hash function and array resizing strategy.
    
    Overrides:
    
    clone in class DoubleArrayList
  - removeAll
```
public int removeAll(DoubleLookupContainer c)
```
    Default implementation uses a predicate for removal.
    
    Specified by:
    
    removeAll in interface DoubleCollection
    
    Returns:
    
    Returns the number of removed elements.
  - retainAll
```
public int retainAll(DoubleLookupContainer c)
```
    Default implementation uses a predicate for retaining.
    
    Specified by:
    
    retainAll in interface DoubleCollection
    
    Returns:
    
    Returns the number of removed elements.
  - retainAll
```
public int retainAll(DoublePredicate predicate)
```
    Default implementation redirects to DoubleCollection.removeAll(DoublePredicate) and negates the predicate.
    
    Specified by:
    
    retainAll in interface DoubleCollection
    
    Returns:
    
    Returns the number of removed elements.
  - toString
```
public java.lang.String toString()
```
    Convert the contents of this container to a human-friendly string.
    
    Overrides:
    
    toString in class java.lang.Object
