Method Details

clear

public void clear()

Description copied from interface: ValueStack

Clears all values.

Specified by:

clear in interface ValueStack<V>

Overrides:

clear in class DefaultValueStack<V>

restoreSnapshot

public void restoreSnapshot(Object snapshot)

Description copied from interface: ValueStack

Restores the stack state as previously returned by ValueStack.takeSnapshot(). This cost of running this operation is negligible and independent from the size of the stack.

Specified by:

restoreSnapshot in interface ValueStack<V>

Overrides:

restoreSnapshot in class DefaultValueStack<V>

Parameters:

snapshot - a snapshot object previously returned by ValueStack.takeSnapshot()

push

public void push(V value)

Description copied from interface: ValueStack

Pushes the given value onto the stack. Equivalent to push(0, value).

Specified by:

push in interface ValueStack<V>

Overrides:

push in class DefaultValueStack<V>

Parameters:

value - the value

push

public void push(int down,
 V value)

Description copied from interface: ValueStack

Inserts the given value a given number of elements below the current top of the stack.

Specified by:

push in interface ValueStack<V>

Overrides:

push in class DefaultValueStack<V>

Parameters:

down - the number of elements to skip before inserting the value (0 being equivalent to push(value))

value - the value

pop

public V pop(int down)

Description copied from interface: ValueStack

Removes the value the given number of elements below the top of the stack.

Specified by:

pop in interface ValueStack<V>

Overrides:

pop in class DefaultValueStack<V>

Parameters:

down - the number of elements to skip before removing the value (0 being equivalent to pop())

Returns:

the value

poke

public void poke(int down,
 V value)

Description copied from interface: ValueStack

Replaces the element the given number of elements below the current top of the stack.

Specified by:

poke in interface ValueStack<V>

Overrides:

poke in class DefaultValueStack<V>

Parameters:

down - the number of elements to skip before replacing the value (0 being equivalent to poke(value))

value - the value to replace with

swap

public void swap()

Description copied from interface: ValueStack

Swaps the top two stack values.

Specified by:

swap in interface ValueStack<V>

Overrides:

swap in class DefaultValueStack<V>

swap3

public void swap3()

Description copied from interface: ValueStack

Reverses the order of the top 3 stack values.

Specified by:

swap3 in interface ValueStack<V>

Overrides:

swap3 in class DefaultValueStack<V>

swap4

public void swap4()

Description copied from interface: ValueStack

Reverses the order of the top 4 stack values.

Specified by:

swap4 in interface ValueStack<V>

Overrides:

swap4 in class DefaultValueStack<V>

swap5

public void swap5()

Description copied from interface: ValueStack

Reverses the order of the top 5 stack values.

Specified by:

swap5 in interface ValueStack<V>

Overrides:

swap5 in class DefaultValueStack<V>

swap6

public void swap6()

Description copied from interface: ValueStack

Reverses the order of the top 5 stack values.

Specified by:

swap6 in interface ValueStack<V>

Overrides:

swap6 in class DefaultValueStack<V>

log

protected void log(String action)
