  Gets the size in memory of the attribute's data.
  

• void read (const DataType &mem_type, void *buf) const

  Reads data from this attribute.
  

• void read (const DataType &mem_type, H5std_string &strg) const

  This is an overloaded member function, provided for convenience. It reads a H5std_string from this attribute.
  

• void write (const DataType &mem_type, const void *buf) const

  Writes data to this attribute.
  

• void write (const DataType &mem_type, const H5std_string &strg) const

  This is an overloaded member function, provided for convenience. It writes a H5std_string to this attribute.
  

• virtual H5std_string fromClass () const

  Returns this class name.
  

• Attribute (const hid_t attr_id)

  Creates an Attribute object using the id of an existing attribute.
  

• Attribute (const Attribute &original)

  Copy constructor: makes a copy of the original Attribute object.
  

• Attribute ()

  Default constructor: Creates a stub attribute.
  

• virtual hid_t getId () const
• virtual ~Attribute ()

  Properly terminates access to this attribute.
