Detailed Description

Class RWSlistCollectablesStack represents a restricted interface to class RWSlistCollectables to implement a last in first out (LIFO) stack. A stack is a sequential list for which all insertions and deletions are made at one end (the beginning of the list). Hence, the ordering is determined externally by the ordering of the insertions. Duplicates are allowed.

An object stored by RWSlistCollectablesStack must inherit from abstract base class RWCollectable. You must use the virtual function isEqual() (see class RWCollectable) to find a match between a target and an item in the stack.

This class corresponds to the Smalltalk class Stack.

Constructor & Destructor Documentation

RWSlistCollectablesStack::RWSlistCollectablesStack

(

)

Constructs an empty stack.

RWSlistCollectablesStack::RWSlistCollectablesStack ( RWCollectable *  a )

inline

Constructs a stack with one entry a.

RWSlistCollectablesStack::RWSlistCollectablesStack ( const RWSlistCollectablesStack &  stk )

inline

Makes a shallow copy of stk.

RWSlistCollectablesStack::RWSlistCollectablesStack ( RWSlistCollectablesStack &&  stk )

inline

Move constructor. The constructed RWSlistCollectablesStack takes ownership of the data owned by stk.

Condition:

This method is available only on platforms with rvalue reference support.

Member Function Documentation

virtual RWCollectable* RWSlistCollectablesStack::append ( RWCollectable *  a )

inlineprivatevirtual

Adds a to the end of the collection and returns it. Returns rwnil if the insertion was unsuccessful.

Reimplemented from RWSlistCollectables.

virtual RWCollectable* RWSlistCollectablesStack::copy ( ) const

virtual

Returns a new, copy-constructed object of the same type as self. The caller is responsible for deleting the object.

Reimplemented from RWSlistCollectables.

virtual RWCollectable* RWSlistCollectablesStack::insert ( RWCollectable *  a )

inlinevirtual

Same as push().

Reimplemented from RWSlistCollectables.

virtual RWClassID RWSlistCollectablesStack::isA ( ) const

virtual

Returns __RWSLISTCOLLECTABLESSTACK, i.e. a class identifier, that identifies this object's class.

Reimplemented from RWSlistCollectables.

virtual bool RWSlistCollectablesStack::isEqual ( const RWCollectable *  t ) const

virtual

Behaves as if compareTo(t) was invoked, returning true if the result equals 0, false otherwise.

Reimplemented from RWSlistCollectables.

virtual RWCollectable* RWSlistCollectablesStack::newSpecies ( ) const

virtual

Returns a new, default-constructed object of the same type as self. The caller is responsible for deleting the object.

Reimplemented from RWSlistCollectables.

RWSlistCollectablesStack& RWSlistCollectablesStack::operator= ( RWSlistCollectablesStack &&  rhs )

inline

Move assignment. Self takes ownership of the data owned by rhs.

Condition:

This method is available only on platforms with rvalue reference support.

RWSlistCollectablesStack& RWSlistCollectablesStack::operator= ( const RWSlistCollectablesStack &  rhs )

inline

Assignment operator. Makes a shallow copy of rhs.

RWCollectable* RWSlistCollectablesStack::pop ( )

inline

Removes and returns the item at the top of the stack, or returns rwnil if the stack is empty.

void RWSlistCollectablesStack::push ( RWCollectable *  a )

inline

Adds an item to the top of the stack.

virtual RWCollectable* RWSlistCollectablesStack::remove ( const RWCollectable *  )

inlinevirtual

Calls pop(). The argument is ignored.

Reimplemented from RWSlistCollectables.

virtual void RWSlistCollectablesStack::removeAndDestroy ( const RWCollectable *  target )

inlineprivatevirtual

Removes and deletes the first item in the collection which "matches" the object pointed to by target.

Reimplemented from RWCollection.

virtual void RWSlistCollectablesStack::restoreGuts ( RWvistream &  )

virtual

Repeatedly calls the global operator:

RWvistream& operator>>(RWvistream&, RWCollectable*&);

followed by insert(RWCollectable*) for each item in the collection.

Reimplemented from RWCollection.

virtual void RWSlistCollectablesStack::restoreGuts ( RWFile &  )

virtual

Repeatedly calls the global operator:

RWFile&  operator>>(RWFile&, RWCollectable*&);

followed by insert(RWCollectable*) for each item in the collection.

Reimplemented from RWCollection.

RWCollectable* RWSlistCollectablesStack::top ( ) const

inline

Returns the item at the top of the stack or returns nil if the stack is empty.
