Detailed Description

This class implements an iterator through a Value list.

When getting a new value you need to know how to iterate through it. The Value::Iterator will help you here:

Value *val = node->getValue();
Value::Iterator it( val );
while( it.hasNext() ) {
    Value v( it.getNext );
}

Constructor & Destructor Documentation

Iterator() [1/3]

Value::Iterator::Iterator

(

)

The default class constructor.

Iterator() [2/3]

Value::Iterator::Iterator

(

Value *

start

)

The class constructor with the start value.

Parameters

start

[in] The first value for iteration,

Member Function Documentation

getNext()

Value * Value::Iterator::getNext

(

)

Returns the next item and moves the iterator to it.

Returns

The next value, is ddl_nullptr in case of being the last item.

hasNext()

bool Value::Iterator::hasNext

(

)

const

Will return true, if another value is in the list.

Returns

true if another value is there.

operator++() [1/2]

Value::Iterator & Value::Iterator::operator++

(

)

The pre-increment operator.

operator++() [2/2]

const Value::Iterator Value::Iterator::operator++

(

int

)

The post-increment operator.

operator->()

Value * Value::Iterator::operator->

(

)

const

The * operator.

Returns

The instance or ddl_nullptr if end of list is reached.

operator==()

bool Value::Iterator::operator==

(

const Iterator &

rhs

)

const

The compare operator.

Parameters

rhs	[in] The instance to compare.

Returns

true if equal.
