NavGroupReader¶
This page describes the class NavGroupReader
The class NavGroupReader reads attributes and arrays from the navigation group of a qdf file.
This file extends the attribute structure:
struct NavAttributes : Attributes {
uint m_iNumPorts;
uint m_iNumDests;
uint m_iNumDists;
double m_dSampleDist;
uint m_iNumBridges;
};

Public Methods¶
createNavGroupReader¶
static NavGroupReader *createNavGroupReader(const std::string sFileName);
static NavGroupReader *createNavGroupReader(hid_t hFile);
Creates a NavGroupReader object for a qdf file.
sFileNameName of the file to read the navigation data from.
hFileHDF5 handle for the file to read the navigation data from.
Returns a pointer to the NavGroupReader object or NULL on failure.
tryReadAttributes¶
virtual int tryReadAttributes(NavAttributes *pAttributes);
Reads the attributes “NumCells”, “NumPorts”, “NumDests”, “SampleDist” and “NumBridges” in the navigation group into the attribute structure.
pAttributesA pointer to a
NavAttributesobject to hold the attributes.
Returns 0 on succes, or -1 on failure.
readArray¶
virtual int readArray(Navigation *pNavigation, const std::string sArrayName);
Read the specified array from the “Navigation” group of the qdf file.
pNavigationA pointer to the Navigation object into which to read the array,
sArrayNameName of the array in the “Navigation” group of the qdf file.
Returns 0 on succes, or -1 on failure.
readData¶
virtual int readData(Navigation *pNavigation);
Reads the arrays “Multiplicities”, “DestIDs”, and “Distances”.
pNavigationA Pointer to a Navigation object.
Returns 0 on succes, or -1 on failure.
