Enumeration Type Documentation

H5G_obj_t

enum H5G_obj_t

An object has a certain type. The first few numbers are reserved for use internally by HDF5. Users may add their own types with higher values. The values are never stored in the file – they only exist while an application is running. An object may satisfy the ‘isa’ function for more than one type.

Deprecated:

Enumerator
H5G_UNKNOWN	Unknown object type
H5G_GROUP	Object is a group
H5G_DATASET	Object is a dataset
H5G_TYPE	Object is a named data type
H5G_LINK	Object is a symbolic link
H5G_UDLINK	Object is a user-defined link
H5G_RESERVED_5	Reserved for future use
H5G_RESERVED_6	Reserved for future use
H5G_RESERVED_7	Reserved for future use

H5G_storage_type_t

enum H5G_storage_type_t

Types of link storage for groups

Enumerator
H5G_STORAGE_TYPE_UNKNOWN	Unknown link storage type
H5G_STORAGE_TYPE_SYMBOL_TABLE	Links in group are stored with a "symbol table" (this is sometimes called "old-style" groups)
H5G_STORAGE_TYPE_COMPACT	Links are stored in object header
H5G_STORAGE_TYPE_DENSE	Links are stored in fractal heap & indexed with v2 B-tree
