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(java.lang.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.- Overrides:
clone
in classLongArrayList
-
removeAll
public int removeAll(LongLookupContainer c)
Default implementation uses a predicate for removal.- Specified by:
removeAll
in interfaceLongCollection
- Returns:
- Returns the number of removed elements.
-
retainAll
public int retainAll(LongLookupContainer c)
Default implementation uses a predicate for retaining.- Specified by:
retainAll
in interfaceLongCollection
- Returns:
- Returns the number of removed elements.
-
retainAll
public int retainAll(LongPredicate predicate)
Default implementation redirects toLongCollection.removeAll(LongPredicate)
and negates the predicate.- Specified by:
retainAll
in interfaceLongCollection
- Returns:
- Returns the number of removed elements.
-
toString
public java.lang.String toString()
