## Detailed Description

Abstract base class for User Identity Negotiation user items.

## Constructor & Destructor Documentation

## ◆ UserIdentityNegotiationSubItem() [1/2]

UserIdentityNegotiationSubItem::UserIdentityNegotiationSubItem | ( | const unsigned char | itemType | ) |

Constructor.

Parameters

  itemType | Must be set to 0x58 for requests, 0x59 for acknowledgements (done in constructors of sub classes)

Referenced by UserIdentityNegotiationSubItem(), and operator=().

## ◆ UserIdentityNegotiationSubItem() [2/2]

UserIdentityNegotiationSubItem::UserIdentityNegotiationSubItem | ( | const UserIdentityNegotiationSubItem & | src | ) |
| inline

Copy constructor.

Needed to keep some compilers quiet.

Parameters

  src | item that should be copied from.

References UserIdentityNegotiationSubItem(), m_itemType, and m_reserved.

## Member Function Documentation

## ◆ dump()

virtual void UserIdentityNegotiationSubItem::dump | ( | STD_NAMESPACE ostream & | outstream | ) | const
| pure virtual

Dump content of this user identity sub item to output stream.

Parameters

  outstream | The stream to dump to

Implemented in UserIdentityNegotiationSubItemAC, and UserIdentityNegotiationSubItemRQ.

## ◆ getItemType()

virtual unsigned char UserIdentityNegotiationSubItem::getItemType | ( |  | ) | const
| inlinevirtual

Returns item type, which is 0x58 for requests, and 0x58 for acknowledgements.

Returns
  The item type = 0x58 or 0x59

References m_itemType.

## ◆ getReserved()

virtual unsigned char UserIdentityNegotiationSubItem::getReserved | ( |  | ) | const
| inlinevirtual

Returns reserved field, which is 0 in this implementation (see DICOM standard)

Returns
  Content of reserved field = 0

References m_reserved.

## ◆ operator=()

UserIdentityNegotiationSubItem & UserIdentityNegotiationSubItem::operator= | ( | const UserIdentityNegotiationSubItem & |  | ) |
| private

Undefined private assignment operator.

Needed to keep some compilers quiet.

Returns
  Reference to "this" object

References UserIdentityNegotiationSubItem().

## ◆ parseFromBuffer()

virtual OFCondition UserIdentityNegotiationSubItem::parseFromBuffer | ( | unsigned char * | readBuffer,
|  | unsigned long & | bytesRead,
|  | unsigned long | availData )
| pure virtual

Parse item from buffer.

The buffer has to start with the correct user item type.

Parameters

  readBuffer | The buffer to read from (input and output). The pointer to the buffer gets incremented by "bytesRead" bytes.
  bytesRead | Returns number of bytes read by this function
  availData | Size of the buffer for reading

Returns
  EC_Normal if successful, error code otherwise

Implemented in UserIdentityNegotiationSubItemAC, and UserIdentityNegotiationSubItemRQ.

## ◆ pduType()

virtual unsigned char UserIdentityNegotiationSubItem::pduType | ( |  | ) | const
| pure virtual

Denotes whether instance is part of a request (DUL_TYPEASSOCIATERQ) or acknowledgement PDU (DUL_TYPEASSOCIATEAC)

Returns
  Constant for either request of acknowledgement message.

Implemented in UserIdentityNegotiationSubItemAC, and UserIdentityNegotiationSubItemRQ.

## ◆ stream()

virtual OFCondition UserIdentityNegotiationSubItem::stream | ( | unsigned char * | targetBuffer,
|  | unsigned long & | lengthWritten ) const
| pure virtual

Stream the package into a byte stream for network transmission.

Parameters

  targetBuffer | The buffer to stream to
  lengthWritten | Returns number of bytes written to buffer

Returns
  EC_Normal, if successful, error code otherwise

Implemented in UserIdentityNegotiationSubItemAC, and UserIdentityNegotiationSubItemRQ.

## ◆ streamedLength()

virtual OFCondition UserIdentityNegotiationSubItem::streamedLength | ( | unsigned long & | length | ) | const
| pure virtual

Computes total length of item if streamed to a buffer.

Parameters

  length | - [out] The total length of the item in bytes

Returns
  EC_Normal if successful, error code otherwise

Implemented in UserIdentityNegotiationSubItemAC, and UserIdentityNegotiationSubItemRQ.

## Member Data Documentation

## ◆ m_itemType

const unsigned char UserIdentityNegotiationSubItem::m_itemType
| private

Item type of this user item.

For User Identity Negotiation, this is always 0x58 for requests and 0x59 for acknowledgements.
