Detailed Description

This class has an object of the TSglQue class, which represents the digits of an integer number list. It is derived from the CActive class to handle asynchronous user inputs. It has methods to:

• edit the linked list
• traverse the linked list using an iterator

CLongNumber * CLongNumber::NewL

(

CConsoleBase *

aConsole

)

[static]

Creates an object of the CLongNumber class.

Parameters:

aConsole

The user console.

Returns:

A pointer to the object of the CLongNumber class.

Definition at line 42 of file longnumber.cpp.

void CLongNumber::RunL

(

)

Handles the key-press events for this active object.

Definition at line 76 of file longnumber.cpp.

void CLongNumber::DoCancel

(

)

Cancel any outstanding request.

Definition at line 300 of file longnumber.cpp.

void CLongNumber::AddToScheduler

(

)

Adds this active object to the active scheduler

Definition at line 68 of file longnumber.cpp.

void CLongNumber::ReadNumber

(

)

Reads a number from the console.

Definition at line 220 of file longnumber.cpp.

void CLongNumber::PrintNumber

(

)

Prints the number.

Definition at line 230 of file longnumber.cpp.

void CLongNumber::InitializeIter

(

)

Sets the iterator to the first element of the list.

Definition at line 258 of file longnumber.cpp.

TBool CLongNumber::GetNumber

(

TInt &

aValue

)

Gets the integer number of the TDigit node, which is pointed to by the iterator.

Parameters:

aValue

The reference to an integer. On return, this stores the value of the digit.

Returns:

EFalse if the iterator has reached the end of the list, else ETrue.

Definition at line 269 of file longnumber.cpp.

TBool CLongNumber::Slide

(

)

Moves the iterator to the next node of the list.

Returns:

EFalse, if the iterator has reached the end of the list, else ETrue.
