Detailed Description

Class RWSlistCollectablesQueue represents a restricted interface to class RWSlistCollectables to implement a first in first out (FIFO) queue. A queue is a sequential list for which all insertions are made at one end (the "tail"), and all removals are made at the other end (the "head"). Hence, the ordering is determined externally by the ordering of the insertions. Duplicates are allowed.

An object stored by RWSlistCollectablesQueue 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 queue.

This class corresponds to the Smalltalk class Queue.

Constructor & Destructor Documentation

RWSlistCollectablesQueue::RWSlistCollectablesQueue

(

)

Constructs an empty queue.

RWSlistCollectablesQueue::RWSlistCollectablesQueue ( RWCollectable *  a )

inline

Constructs a queue with single item a.

RWSlistCollectablesQueue::RWSlistCollectablesQueue ( const RWSlistCollectablesQueue &  queue )

inline

Makes a shallow copy of queue.

RWSlistCollectablesQueue::RWSlistCollectablesQueue ( RWSlistCollectablesQueue &&  queue )

inline

Move constructor. The constructed RWSlistCollectablesQueue takes ownership of the data owned by queue.

Condition:

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

Member Function Documentation

virtual RWClassID RWSlistCollectablesQueue::isA ( ) const

virtual

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

Reimplemented from RWSlistCollectables.

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

virtual

Returns true if the collectable object "matches" the object at address t. The default definition is:

return this == t;

i.e., both objects have the same address (a test for identity). The definition may be redefined in any consistent way.

Reimplemented from RWSlistCollectables.

virtual RWCollectable* RWSlistCollectablesQueue::newSpecies ( ) const

virtual

Allocates a new object off the heap of the same type as self and returns a pointer to it. You are responsible for deleting the object when done with it.

Reimplemented from RWSlistCollectables.

RWSlistCollectablesQueue& RWSlistCollectablesQueue::operator= ( RWSlistCollectablesQueue &&  rhs )

inline

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

Condition:

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

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

inline

Assignment operator. Makes a shallow copy of rhs.

RWCollectable* RWSlistCollectablesQueue::prepend ( RWCollectable *  c )

inlineprivatevirtual

Adds c to the beginning of the collection and returns it. Returns rwnil if the insertion was unsuccessful.

Reimplemented from RWSlistCollectables.

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

inlinevirtual

Calls get(). The argument is ignored.

Reimplemented from RWSlistCollectables.

virtual void RWSlistCollectablesQueue::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.
