TFloatArrayStack
public TFloatArrayStack(int capacity) Creates a newTFloatArrayStack
instance with the specified capacity.- Parameters:
capacity
- the initial depth of the stack
-
TFloatArrayStack

Method Details
-
getNoEntryValue
public float 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 interfaceTFloatStack
- Returns:
- the value that represents null
-
push
public void push(float val) Pushes the value onto the top of the stack.- Specified by:
push
in interfaceTFloatStack
- Parameters:
val
- anfloat
value
-
pop
public float pop()Removes and returns the value at the top of the stack.- Specified by:
pop
in interfaceTFloatStack
- Returns:
- an
float
value
-
peek
public float peek()Returns the value at the top of the stack.- Specified by:
peek
in interfaceTFloatStack
- Returns:
- an
float
value
-
size
public int size()Returns the current depth of the stack.- Specified by:
size
in interfaceTFloatStack
-
clear
public void clear()Clears the stack.- Specified by:
clear
in interfaceTFloatStack
-
toArray
public float[] 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 interfaceTFloatStack
- Returns:
- an
float[]
value
-
toArray
public void toArray(float[] 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 interfaceTFloatStack
- Parameters:
dest
- the array to copy into.
-
toString
Returns a String representation of the list, top to bottom. -
