getNoEntryValue
public short 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 interfaceTShortStack
- Returns:
- the value that represents null
-
push
public void push(short val) Pushes the value onto the top of the stack.- Specified by:

toArray
public short[] 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 interfaceTShortStack
- Returns:
- an
short[]
value
-
toArray
public void toArray(short[] 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.
- Specified by:
toArray
in interfaceTShortStack
- Parameters:
dest
- the array to copy into.
