TIntArrayStack
public TIntArrayStack()Creates a newTIntArrayStack
instance with the default capacity. -
TIntArrayStack
public TIntArrayStack(int capacity) Creates a newTIntArrayStack
instance with the specified capacity.- Parameters:
capacity
- the initial depth of the stack
-
TIntArrayStack
public TIntArrayStack(int capacity, int no_entry_value) Creates a newTIntArrayStack
instance with the specified capacity.- Parameters:
capacity
- the initial depth of the stackno_entry_value
- value that represents null
-
TIntArrayStack
Creates a newTIntArrayStack
instance that is a copy of the instanced passed to us.- Parameters:
stack
- the instance to copy
-
-
Method Details
-
getNoEntryValue
public int 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 interfaceTIntStack
- Returns:
- the value that represents null
-
push
public void push(int val) Pushes the value onto the top of the stack. -
pop
public int pop()Removes and returns the value at the top of the stack. -
peek
public int peek()Returns the value at the top of the stack. -
size
public int size()Returns the current depth of the stack. -
clear
public void clear()Clears the stack. -
toArray
public int[] 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. -
toArray
public void toArray(int[] 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.
