saslib documentation

This package contains two libraries of SAS utilities: saslib and sasdal. The latter contains utilities that make used of the dal.

sasdal

C++ utility functions that make use of the DAL

The interface from sasdal.h

is as follows:

inline void setStringColumnRow(const ColumnData *c, const unsigned long row, const string &str); inline string getStringColumnData(const ColumnData *c, const unsigned long row = 0);

Event attributes

The Fortran module eventattributes implements GV/XMM/1999-01. The following functions are available in this module. There is also a C++ implementation event attributes in EventAttributes.h. This is as follows:

namespace EventAttributes { // Attributes can share the same number: it means that they apply to // different instruments. // Try to keep the info/rejection attributes in the first/last 16 // bits. enum EvAtt { DIAGONAL = 0, CLOSE_TO_CCD_BORDER = 1, CLOSE_TO_CCD_WINDOW = 2, CLOSE_TO_NODE_BOUNDARY = 3, ON_NODE0 = 3, ON_OFFSET_COLUMN = 3, ON_NODE1, NEXT_TO_OFFSET_COLUMN = 4, CLOSE_TO_ONBOARD_BADPIX = 5, CLOSE_TO_BRIGHTPIX = 6, CLOSE_TO_FLICKERINGPIX = 7, CLOSE_TO_DEADPIX = 8, CLOSE_TO_BADCOL = 9, CLOSE_TO_BADROW = 10, IN_SPOILED_FRAME = 11, UNKNOWN_RAWX_PATTERN = 12, ONBOARD_SER = 12, OUT_OF_FOV = 16, IN_BAD_FRAME = 17, OUTSIDE_GTI = 18, COSMIC_RAY= 19, BAD_SHAPE = 19, MIP_ASSOCIATED = 20, ON_BADPIX = 21, REJECTED_BY_GATTI, SECONDARY = 22, TRAILING, NEXT_TO_CCD_BORDER = 23, NEXT_TO_BADPIX = 24, OUT_OF_CCD_WINDOW = 25, OUTSIDE_THRESHOLDS = 26, BELOW_ACCEPTANCE = 27, ON_BADROW = 28, BAD_E3E4 = 29, EVLIST_LOCAL = 31, NUMBER_OF }; // These are the rejection masks for the instruments. const int RGS_REJECTION_MASK = 1 << (int) ON_BADPIX | 1 << (int) NEXT_TO_BADPIX | 1 << (int) BAD_SHAPE | 1 << (int) NEXT_TO_CCD_BORDER | 1 << (int) BELOW_ACCEPTANCE | 1 << (int) IN_BAD_FRAME | 1 << (int) OUTSIDE_GTI; const int EMOS_REJECTION_MASK = 1 << (int) OUT_OF_FOV | 1 << (int) IN_BAD_FRAME | 1 << (int) COSMIC_RAY | 1 << (int) ON_BADPIX | 1 << (int) REJECTED_BY_GATTI | 1 << (int) OUT_OF_CCD_WINDOW | 1 << (int) OUTSIDE_THRESHOLDS; const int EPN_REJECTION_MASK = 1 << (int) OUT_OF_FOV | 1 << (int) IN_BAD_FRAME | 1 << (int) COSMIC_RAY | 1 << (int) ON_BADPIX | 1 << (int) SECONDARY | 1 << (int) TRAILING | 1 << (int) MIP_ASSOCIATED ; const int CLEAR_ALL_FLAGS = 0; const string COLUMN_NAME = "FLAG"; const Dal::DataType COLUMN_TYPE = Dal::Int32; // Set the bit corresponding to the event attribute void setEventAttribute(int & v, const EvAtt n); // Add a table attribute void setEventAttribute(Table *table, const EvAtt n); // Propagate table attributes from one table to another void copyEventAttributes(const Table *fromtable, Table *totable); // Specialized functions to set instrument specific rejection masks // with a fixed name void setEmosRejectionMask(Table *table); void setEpnRejectionMask(Table *table); void setRgsRejectionMask(Table *table); const vector names(); EvAtt lookup(const string & name); bool eventAttributeIsSet(const Table *table, const EvAtt n); bool eventAttributeIsSet(int & v, const EvAtt n); };

saslib

Directory

This is a C++ class to list the contents of a directory. File names can be filtered with patterns. Multiple filter patterns are possible, if they are separated with |. For instance:

Directory d(".");
d.filter("*.cc|*.h");

By default a Directory object only lists entries it finds in the directory indicated in the constructor. It is possible to alter this behavior with the member function recurse(bool). For instance:

Directory d(".");
d.filter("*.cc|*.h");
d.recurse(true);

The complete interface specification from Directory.h is as follows:

class Directory: public list { public: Directory(const string name = ".", const string pattern = "*", const bool recurse = false); Directory(const DirEntry * d, const string pattern = "*", const bool recurse = false); void filter(const string pattern); string filter() const; void recurse(const bool dorecurse); bool recurse() const; bool isOk() const; string name() const; void print(ostream & os) const; private: // disallowed Directory(const Directory & rhs); void operator=(Directory & rhs); bool operator==(const Directory & rhs); bool operator!=(const Directory & rhs); void init(); void scan(); void reset(); bool _isOk; string _name; string _pattern; string _separator; bool _recurse; }; ostream & operator<<(ostream &os, const Directory &d);

DirEntry

This is an abstract C++ class that contains one directory entry (a file). A DirEntry object has methods to inquire about the most common file properties (name, dirname, basename, size). It has also a method to generate the MD5 signature of the file.

The complete interface specification from DirEntry.h is as follows:

class DirEntry : public virtual DigitallySignable { public: virtual ~DirEntry() {} virtual string name() const = 0; virtual string dirname() const = 0; virtual string basename() const = 0; virtual off_t size() const = 0; virtual bool isDir() const = 0; virtual void print(ostream & os) const = 0; virtual bool operator==(const DirEntry & rhs) const = 0; virtual bool operator!=(const DirEntry & rhs) const = 0; }; inline ostream & operator<<(ostream & os, const DirEntry & d) { d.print(os); return os; }

DirEntry objects are instantiated through the DirEntryFactory. For example:

#include "DirEntryFactory.h" // ... DirEntry * d = dirEntryFactory->dirEntry("file.cc"); d->sign();

Digital signatures

The MD5 code was taken from rfc1321. There is an abstarct interface to a digitally signable object, with an implementation in DirEntry.

The interface from DigitallySignable.h is:

class DigitallySignable { public: virtual void sign() = 0; virtual string signature() const = 0; virtual bool isSigned() const = 0; virtual ~DigitallySignable() {}; };
