TLongArrayStack
public TLongArrayStack()
Creates a newTLongArrayStackinstance with the default capacity.
-
TLongArrayStack
public TLongArrayStack(int capacity)
Creates a newTLongArrayStackinstance with the specified capacity.- Parameters:
capacity- the initial depth of the stack
-
TLongArrayStack

Method Detail
-
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:
getNoEntryValuein interfaceTLongStack- Returns:
- the value that represents null
-
push
public void push(long val)
Pushes the value onto the top of the stack.- Specified by:
pushin interfaceTLongStack- Parameters:
val- anlongvalue
-
pop
public long pop()
Removes and returns the value at the top of the stack.- Specified by:
popin interfaceTLongStack- Returns:
- an
longvalue
-
peek
public long peek()
Returns the value at the top of the stack.- Specified by:
peekin interfaceTLongStack- Returns:
- an
longvalue
-
size
public int size()
Returns the current depth of the stack.- Specified by:
sizein interfaceTLongStack
-
clear
public void clear()
Clears the stack.- Specified by:
clearin 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:
toArrayin 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.
- Specified by:
toArrayin interfaceTLongStack- Parameters:
dest- the array to copy into.
-
toString
public java.lang.String toString()
Returns a String representation of the list, top to bottom.- Overrides:
toStringin classjava.lang.Object- Returns:
- a
Stringvalue
