Detailed Description

Class H5File represents an HDF5 file.

It inherits from H5Location and CommonFG.

Examples:: chunks.cpp, compound.cpp, create.cpp, extend_ds.cpp, h5group.cpp, readdata.cpp, and writedata.cpp.

Constructor & Destructor Documentation

H5::H5File::H5File	(	const char *	name,
		unsigned int	flags,
		const FileCreatPropList &	create_plist = `FileCreatPropList::DEFAULT`,
		const FileAccPropList &	access_plist = `FileAccPropList::DEFAULT`
	)

Creates or opens an HDF5 file depending on the parameter flags.

Parameters

name	- IN: Name of the file
flags	- IN: File access flags
create_plist	- IN: File creation property list, used when modifying default file meta-data. Default to FileCreatPropList::DEFAULT
access_plist	- IN: File access property list. Default to FileAccPropList::DEFAULT

Description

Valid values of flags include:

H5F_ACC_TRUNC - Truncate file, if it already exists, erasing all data previously stored in the file.
H5F_ACC_EXCL - Fail if file already exists. H5F_ACC_TRUNC and H5F_ACC_EXCL are mutually exclusive
H5F_ACC_DEBUG - print debug information. This flag is used only by HDF5 library developers; it is neither tested nor supported for use in applications.

: For info on file creation in the case of an already-open file, please refer to the Special case section in the C layer Reference Manual at: http://www.hdfgroup.org/HDF5/doc/RM/RM_H5F.html#File-Create

H5::H5File::H5File	(	const H5std_string &	name,

	)

This is another overloaded constructor. It differs from the above constructor only in the type of the name argument.

Parameters

name	- IN: Name of the file - `H5std_string`
flags	- IN: File access flags
create_plist	- IN: File creation property list, used when modifying default file meta-data. Default to FileCreatPropList::DEFAULT
access_plist	- IN: File access property list. Default to FileAccPropList::DEFAULT
