getNoEntryValue
public long getNoEntryValue()
Returns the value that is used to represent null. The default value is generally zero, but can be changed during construction of the collection.- Specified by:
getNoEntryValue
in interfaceTLongStack
- Returns:
- the value that represents null
-
push
public void push(long val)
Pushes the value onto the top of the stack.- Specified by:
push
in interfaceTLongStack
- Parameters:
val
- anlong
value
-
pop
public long pop()
Removes and returns the value at the top of the stack.- Specified by:
pop
in interfaceTLongStack
- Returns:
- an
long
value
-
peek
public long peek()

clear
public void clear()
Clears the stack.- Specified by:
clear
in interfaceTLongStack
-
toArray
public long[] toArray()
Copies the contents of the stack into a native array. Note that this will NOT pop them out of the stack. The front of the list will be the top of the stack.- Specified by:
toArray
in interfaceTLongStack
- Returns:
- an
long[]
value
-
toArray
public void toArray(long[] dest)
Copies a slice of the list into a native array. Note that this will NOT pop them out of the stack. The front of the list will be the top of the stack.If the native array is smaller than the stack depth, the native array will be filled with the elements from the top of the array until it is full and exclude the remainder.
