Method Detail

getNoEntryValue

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.

Returns:
the value that represents null

push

void push(long val)
Pushes the value onto the top of the stack.

Parameters:
val - an long value

pop

long pop()
Removes and returns the value at the top of the stack.

Returns:
an long value

peek

long peek()
Returns the value at the top of the stack.

Returns:
an long value

size

int size()
Returns the current depth of the stack.


clear

void clear()
Clears the stack.


toArray

long[] toArray()
Copies the contents of the stack into a native array. Note that this will NOT pop them out of the stack.

Returns:
an long[] value

toArray

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.
