## Detailed Description

Interface class for a Storage Service Class Provider (SCP).

This class supports C-STORE and C-ECHO messages as an SCP. The received datasets are always stored as DICOM files with the same Transfer Syntax as used for the network transmission. Both the generation of the directory structure and the filenames can be configured by the user.

Note
  The current implementation always requires to load a so-called association negotiation profile from a configuration file, which specifies the list of Presentation Contexts (i.e. combination of SOP Class and Transfer Syntaxes) to be supported by this Storage SCP. If no association negotiation profile is loaded, the SCP will only support the Verification SOP Class (with Default Transfer Syntax, i.e. C-ECHO with Implicit VR Little Endian), which is required for all DICOM Service Class Providers.

|  | DcmFileFormat & | fileformat )
| protectedvirtual

check the given C-STORE request and dataset for validity.

This method is called by handleIncomingCommand() before sending the response in order to determine the DIMSE status code to be used for the response message. If this check has been passed successfully, the received dataset is stored as a DICOM file.

Parameters

  reqMessage | C-STORE request message data structure to be checked and processed
  fileformat | DICOM fileformat structure containing the C-STORE request dataset to be checked and processed

Returns
  DIMSE status code to be used for the C-STORE response

| protectedvirtual

generate a directory and file name for a DICOM dataset that has been received.

The naming scheme can be specified by the methods setDirectoryGenerationMode(), setFilenameGenerationMode() and setFilenameExtension(). Please note that this method only generates the names but neither creates the directory structure nor the DICOM file.

Parameters

  filename | reference to variable that will store the resulting filename
  directoryName | reference to variable that will store the resulting directory name (including the main output directory)
  sopClassUID | SOP Class UID of the DICOM object. This is both an input and output parameter. If an empty value is passed to this method, the value of the data element SOP Class UID (0008,0016) is determined from the DICOM dataset.
  sopInstanceUID | SOP Instance UID of the DICOM object. This is both an input and output parameter. If an empty value is passed to this method, the value of the data element SOP Instance UID (0008,0018) is determined from the dataset.
  dataset | pointer to dataset for which the directory and file name is to be generated (optional)

| protectedvirtual

handler that is called for each incoming command message.
