Detailed Description

List of DtRadioDescriptor subclasses that can be read from a RW type file.

This class owns all descriptors contained on the list and deletes them when the list is destroyed.

Member Function Documentation

DtRadioDescriptorList& DtRadioDescriptorList::operator=

(

const DtRadioDescriptorList &

orig

)

Assignment operator; removes and deletes all entries on the left hand side - then clones all entries on the right side list, adding them to the left side list.

virtual DtRadioDescriptorList* DtRadioDescriptorList::clone

(

DtReaderWriterRegistry *

parentRegistry = 0

)

[virtual]

virtual DtVrfRadioDescriptor* DtRadioDescriptorList::addRadioDescriptor

(

const DtVrfRadioDescriptor &

descriptor

)

[virtual]

Clones the descriptor and adds it to the list.

Note:

Any existing descriptor with the same name will be replaced.

virtual const DtVrfRadioDescriptor* DtRadioDescriptorList::lookupRadioDescriptor

(

const DtString &

name

)

const [virtual]

Searches the list for a descriptor of the specified name, and returns a pointer to it if it exists.

virtual DtVrfRadioDescriptor* DtRadioDescriptorList::lookupRadioDescriptor

(

const DtString &

name

)

[virtual]

void DtRadioDescriptorList::emptyList

(

)

[protected]

Removes all descriptors from the list, and destroys them.

void DtRadioDescriptorList::copyList

(

const DtRadioDescriptorList &

orig

)

[protected]

virtual void DtRadioDescriptorList::addRadioDescriptor

(

DtVrfRadioDescriptor *

descriptor

)

[protected, virtual]

Adds this descriptor to the list.

Does not clone the descriptor.

Note:

Any existing descriptor with the same name will be replaced.

virtual DtListItem* DtRadioDescriptorList::lookupRadioDescriptorItem

(

const DtString &

name

)

const [protected, virtual]

Looks up the descriptor and returns the list item that points to it.

virtual DtlObjPtr DtRadioDescriptorList::getData	(	DtlObjPtr	args,
		const DtFilename &	searchPath,
		const DtVariableBindingsList &	variableBindings
	)		[protected, virtual]

This method must be overridden by a subclass.

Within this method, new instances of the DtReaderWriter subclass that is being handled by this list must be created, and then retrieved from the mtl stream, using the getSelf member of that item.

Here is some sample code that could be used to implement a override of this class: (This is used in the DtRwIntegerList::getData() method)

 DtlObjPtr nameObj = DtcCar(args);
 DtRwInt* value = new DtRwInt(nameObj->pname());
 value->getSelf(args, searchPath, variableBindings);
 this->add(value);
 return DtcCdr(DtcCdr(args));

Implements DtRwList.
