Detailed Description

double-linked list class that maintains pointers to DcmObject instances.

The remove operation does not delete the object pointed to, however, the destructor will delete all elements pointed to

Constructor & Destructor Documentation

DcmList()

DcmList::DcmList ( const DcmList &  newList )

private

private undefined copy assignment operator

Parameters

newList

documented to avoid doxygen warnings

Member Function Documentation

append()

DcmObject * DcmList::append

(

DcmObject *

obj

)

insert object at end of list

Parameters

obj	pointer to object

Returns

pointer to object

deleteAllElements()

void DcmList::deleteAllElements

(

)

Remove and delete all elements from list.

Thus, the elements' memory is also freed by this operation. The list is empty after calling this function.

get()

DcmObject * DcmList::get

(

E_ListPos

pos = ELP_atpos

)

get pointer to element in list at given position

Parameters

pos	position indicator

Returns

pointer to object

insert()

DcmObject * DcmList::insert	(	DcmObject *	obj,
		E_ListPos	pos = ELP_next
	)

insert object relative to current position and indicator

Parameters

obj	pointer to object
pos	position indicator

Returns

pointer to object

prepend()

DcmObject * DcmList::prepend

(

DcmObject *

obj

)

insert object at start of list

Parameters

obj	pointer to object

Returns

pointer to object

remove()

DcmObject * DcmList::remove

(

)

remove current entry from list, return element

Returns

pointer to removed element, which is not deleted

seek()

DcmObject * DcmList::seek

(

E_ListPos

pos = ELP_next

)

seek within element in list to given position (i.e.

set current element to given position)

Parameters

pos	position indicator

Returns

pointer to new current object

seek_to()

DcmObject * DcmList::seek_to

(

unsigned long

absolute_position

)

seek within element in list to given element index (i.e.

set current element to given index)

Parameters

absolute_position

position index < card()

Returns

pointer to new current object
