\subsection{SICS Generic Data}
|
|
This is an attempt to create a generic interface between SICS data and
|
|
clients. At the bottom of it is a auto resizing array of data. Data
|
|
can be entered into this array either manually or copied from data
|
|
sources such as histogram memories or scans. Data assembled in this
|
|
way, for instance through scripts, can then be forwarded to clients
|
|
either in UUencoded form or as a zipped array.
|
|
|
|
In a later stage this may be extended to support selected mathematical
|
|
operations as well. In another stage this may supersede the uuget and
|
|
zipget methods in the scan, histogram memory and specialized status
|
|
objects.
|
|
|
|
This needs a data structure:
|
|
@d sidastruc @{
|
|
typedef struct {
|
|
pObjectDescriptor pDes;
|
|
int *data;
|
|
char *dataType;
|
|
int dataUsed;
|
|
int currentDataSize;
|
|
}SICSData, *pSICSData;
|
|
|
|
@}
|
|
The fields:
|
|
\begin{description}
|
|
\item[pDes] The standard object descriptor.
|
|
\item[data] The actual data array. This code assumes that sizeof(int)
|
|
== sizeof(float).
|
|
\item[dataType] An array defining the data type for each element of
|
|
data. Supported are: 4 byte int and 4 byte float.
|
|
\item[dataUsed] is the highest data element adressed so far.
|
|
\item[currentDataSize] is the size of data.
|
|
\end{description}
|
|
|
|
This object exports the following functions:
|
|
@d sidafunc @{
|
|
int *getSICSDataPointer(pSICSData self, int start, int end);
|
|
|
|
pSICSData createSICSData(void);
|
|
|
|
void assignSICSType(pSICSData self, int start, int end, int type);
|
|
|
|
int SICSDataFactory(SConnection *pCon, SicsInterp *pSics,
|
|
void *pData,
|
|
int argc, char *argv[]);
|
|
|
|
int SICSDataAction(SConnection *pCon, SicsInterp *pSics,
|
|
void *pData,
|
|
int argc, char *argv[]);
|
|
@}
|
|
\begin{description}
|
|
\item[getSICSDataPointer] returns a pointer to the first element of
|
|
start in the data array. It is also ensured that enough space is
|
|
available till end.
|
|
\item[createSICSData] creates a new SICSData structure.
|
|
\item[SICSDataFactory] is an interpreter function for creating and
|
|
deleting SICSData things.
|
|
\item[SICSDataAction] is the interpreter wrapper function through
|
|
which users may interact with the SICSData element.
|
