Detailed Description

Class representing a node in DcmPath.

A node contains just a pointer to a DcmObject (e.g. a sequence or an item). Additionally an item number is stored which also makes sense in case that the object pointed to is an item. The item number is necessary because when having only a pointer to a DcmItem there is no way to find out at which position the item actually has in the surrounding sequence.

Constructor & Destructor Documentation

DcmPathNode::DcmPathNode ( )

inline

Constructor.

Creates empty path node.

DcmPathNode::DcmPathNode ( DcmObject *  obj, Uint32  itemNo  )

inline

Constructor.

Creates search node from object pointer and item number.

Parameters

obj	[in] The object the search node points to. The memory of the given DICOM object is not handled by the node itself but must be handled (i.e. freed) from outside.
itemNo	[in] The item number that should be set. Only relevant if obj parameter contains an item

DcmPathNode::~DcmPathNode ( )

inline

Destructor.

Nothing to do, the DICOM object is not freed automatically!
