Purpose: Add new C++ wrappers
Description:
Added wrappers for H5Iis_valid, H5Ps/get_nlinks, H5Tget_create_plist,
H5Oopen, H5Oclose and H5Pset_virtual
// Checks if the given ID is valid.
static bool isValid(hid_t an_id);
// Sets the number of soft or user-defined links that can be
// traversed before a failure occurs.
void setNumLinks(size_t nlinks) const;
// Gets the number of soft or user-defined link traversals allowed
size_t getNumLinks() const;
// Returns a copy of the creation property list of a datatype.
PropList getCreatePlist() const;
// Opens an object within a group or a file, i.e., root group.
hid_t getObjId(const char* name,...);
hid_t getObjId(const H5std_string& name,...);
// Closes an object opened by getObjId().
void closeObjId(hid_t obj_id) const;
// Maps elements of a virtual dataset to elements of the source dataset.
void setVirtual(const DataSpace& vspace, const char *src_fname,...);
void setVirtual(const DataSpace& vspace, const H5std_string src_fname,...);
Platforms tested:
Linux/32 2.6 (jam)
Linux/64 (platypus)
Darwin (osx1010test)
