Detailed Description

HDF4 implementation of the NeXus file reader/writer.

The nxH4 namespace provides classes and functions for reading and writing NeXus files in HDF4 format. This implementation uses the HDF4 C API (mfhdf.h, hdf.h) and provides case-insensitive path lookup.

Key Classes:

• PNeXus: Main file reader/writer class
• PNXdata: Template class for storing dataset content
• PNeXusDeadTime: Dead time correction calculator

Requirements:

• HDF4 library (libmfhdf, libhdf)
• HAVE_HDF4 must be defined at compile time

Note

This namespace is only available if compiled with HAVE_HDF4 defined

nxH5 for the HDF5 implementation

nxs::checkHDFType() to determine file format before reading

Enumeration Type Documentation

H4DataType

enum class nxH4::H4DataType

strong

HDF4 data type enumeration.

This enum maps to HDF4 numeric types (DFNT_*) for type-safe dataset handling

Enumerator
kINT32	32-bit signed integer (DFNT_INT32)
kFLOAT32	32-bit floating point (DFNT_FLOAT32)
kFLOAT64	64-bit floating point (DFNT_FLOAT64)
kCHAR8	8-bit character (DFNT_CHAR8)
kUINT32	32-bit unsigned integer (DFNT_UINT32)
kINT16	16-bit signed integer (DFNT_INT16)
kUINT16	16-bit unsigned integer (DFNT_UINT16)
kINT8	8-bit signed integer (DFNT_INT8)
kUINT8	8-bit unsigned integer (DFNT_UINT8)
