CLiwList Class Reference

class CLiwList : public CLiwContainer

Abstract interface for an ordered collection or sequence. Typically, the collection entries are of type TLiwVariant instances. CLiwList offers abstract methods to:

access elements based on an index
remove an element from the collection
append to an element to the collection
remove a key-value pair based on a key
get the total number of stored key-value pairs

A default concrete implementation is provided in the form of specialized class CLiwDefaultList

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! IMPORTANT NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Since container objects are reference counted, they cannot go with CleanupStack::PushL. The issue is solved by using CleanupClosePushL for pushing the container objects into the CleanupStack. Hence CLiwContainer::Close method is introduced common to all container objects.

This implies that the object of this concrete implementation class being created should be pushed into the CleanupStack using CLiwContainer::PushL.

AppendL(const TLiwVariant &)

void

AppendL

(

const TLiwVariant &

aEntry

)

[pure virtual]

Appends an entry to the end of the collection. This is an abstract method.

CLiwDefaultList::AppendL

Parameters

const TLiwVariant & aEntry

an Element to be added to the end of the collection

AtL(TInt, TLiwVariant &)

TBool	AtL	(	TInt	aIndex,
			TLiwVariant &	aEntry
		)	const [pure virtual]

Gets an entry from the collection based on an integeral index.

!!!!!!!!!!!!!!!!!!!!!!!!!! IMPORTANT NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

This is a copy of the value present in the list at the particular index. To ensure proper cleanup TLiwVariant::PushL method should be called beforehand.
