Detailed Description

class DtRwIntrusiveList:

Instances of DtRwIntrusiveList are readable-writable versions of the VR-Link DtIntrusiveList class. Instead of expecting its objects to be derived from DtListedObj, this class expects them to be derived from DtRwListedObj.

In order to use this class, you will have to derive a more specific class from it that implements the special getData function to create the actual list items.

The save format for this class is something like: (list-name (list-elem-name ...element putSelf data...) (list-elem-name ...element putSelf data...) ... )

virtual

Calls remove for all elements in the list.

It does NOT delete the data in the list. Merely removes the data from the list.

virtual

Same as removeAll, except that this DOES delete the data in the list.

DtListItem * DtRwIntrusiveList::itemLookup ( DtRwListedObj *  data ) const

inline

Returns the DtListItem envelope object containing the indicated data element.

This function should never be necessary, it is included solely for completeness and consistency with DtIntrusiveList.

References myList.

virtual void DtRwIntrusiveList::getSelf ( DtlObjPtr  args, const DtFilename &  searchPath, const DtVariableBindingsList &  variableBindings  )

virtual

Reads the contents of the list, using the list-specific getData function below.

Reimplemented from DtReaderWriter.

virtual DtlObjPtr DtRwIntrusiveList::getData ( DtlObjPtr  args, const DtFilename &  searchPath, const DtVariableBindingsList &  variableBindings  )

pure virtual

This special version of getData needs to create the necessary list element object (one that's derived from DtRwListedObj), tell the element to getSelf, and then add the element to the DtRwIntrusiveList.

The return value is ignored.

Reimplemented from DtReaderWriter.

Implemented in DtSimBlock.

virtual DtlObjPtr DtRwIntrusiveList::getLocalData ( DtlObjPtr  args )

virtual

Since getData is usually used for local data, and we're overloading it here to get the list data, use this if you want any data before your lists.

virtual const char* DtRwIntrusiveList::readerWriterType ( ) const

virtual

Used to supply a string type that this reader writer type is.

This can be used in place of dynamic-casting. Also used by the opd editor to determine which type of control to create

Reimplemented from DtReaderWriter.

virtual DtListItem* DtRwIntrusiveList::addToList ( DtRwListedObj *  data, DtRwListedObj *  after  )

Add element to the list just after the indicated item.

Returns the DtListItem envelope object that contains your new element.
