Public Member Functions | |
UserIdentityNegotiationSubItem () | |
Constructor. | |
virtual unsigned char | pduType () const =0 |
Denotes whether instance is part of a request (DUL_TYPEASSOCIATERQ) or acknowledge PDU (DUL_TYPEASSOCIATEAC) | |
virtual unsigned char | getItemType () const |
Returns item type, which is constantly 0x58. | |
virtual unsigned char | getReserved () const |
Returns reserved field, which is 0 in this implementation (see DICOM standard) | |
virtual OFCondition | streamedLength (unsigned long &length) const =0 |
Computes total length of item if streamed to a buffer. | |
virtual OFCondition | parseFromBuffer (unsigned char *readBuffer, unsigned long &bytesRead, unsigned long availData)=0 |
Parse item from buffer. | |
virtual OFCondition | stream (unsigned char *targetBuffer, unsigned long &lengthWritten) const =0 |
Stream the package into a byte stream for network transmission. | |
virtual void | clear ()=0 |
Clears member variables and frees memory. | |
virtual void | dump (STD_NAMESPACE ostream &outstream) const =0 |
Dump content of this user identity sub item to output stream. | |
virtual | ~UserIdentityNegotiationSubItem () |
Destructor, nothing to clean up. | |
Private Attributes | |
const unsigned char | m_itemType |
Item type of this user item. | |
const unsigned char | m_reserved |
Reserved field, should be always sent with value 0 (default) | |

|
pure virtual |
Clears member variables and frees memory.
Implemented in UserIdentityNegotiationSubItemAC, and UserIdentityNegotiationSubItemRQ.
|
pure virtual |
Dump content of this user identity sub item to output stream.
outstream | - [out] The stream to dump to |
Implemented in UserIdentityNegotiationSubItemAC, and UserIdentityNegotiationSubItemRQ.
|
inlinevirtual |
Returns item type, which is constantly 0x58.
Definition at line 70 of file dcuserid.h.
References m_itemType.
|
inlinevirtual |
Returns reserved field, which is 0 in this implementation (see DICOM standard)
Definition at line 76 of file dcuserid.h.
References m_reserved.
|
pure virtual |
Parse item from buffer.
The buffer has to start with the correct user item type.
readBuffer | - [in/out] The buffer to read from. The pointer to the buffer gets incremented by "bytesRead" bytes. |
bytesRead | - [out] Number of bytes read by this function |
availData | - [in] Size of the buffer. |
Implemented in UserIdentityNegotiationSubItemAC, and UserIdentityNegotiationSubItemRQ.
|
pure virtual |
Denotes whether instance is part of a request (DUL_TYPEASSOCIATERQ) or acknowledge PDU (DUL_TYPEASSOCIATEAC)
Implemented in UserIdentityNegotiationSubItemAC, and UserIdentityNegotiationSubItemRQ.
|
pure virtual |
Stream the package into a byte stream for network transmission.
targetBuffer | - [out] The buffer to stream to. |
lengthWritten | - [out] Number of bytes written to buffer |
Implemented in UserIdentityNegotiationSubItemAC, and UserIdentityNegotiationSubItemRQ.
|
pure virtual |
Computes total length of item if streamed to a buffer.
length | - [out] The total ength of the item in bytes |
Implemented in UserIdentityNegotiationSubItemAC, and UserIdentityNegotiationSubItemRQ.
|
private |
Item type of this user item.
For User Identity Negotiation this is always 0x58
