H5P_SET_LINK_CREATION_ORDER
Sets creation order tracking and indexing for links in a group
Procedure:
H5P_SET_LINK_CREATION_ORDER ( gcpl_id, crt_order_flags )
Signature:
herr_t H5Pset_link_creation_order(
hid_t gcpl_id,
unsigned crt_order_flags
)
Fortran90 Interface: h5pset_link_creation_order_f
SUBROUTINE h5pset_link_creation_order_f(gcpl_id, crt_order_flags, hdferr)
IMPLICIT NONE
INTEGER(HID_T), INTENT(IN) :: gcpl_id ! File access property list identifier
INTEGER, INTENT(IN) :: crt_order_flags ! Creation order flag(s):
! H5P_CRT_ORDER_TRACKED_F
! H5P_CRT_ORDER_INDEXED_F
INTEGER, INTENT(OUT) :: hdferr ! Error code
! 0 on success and -1 on failure
END SUBROUTINE h5pset_link_creation_order_f
Parameters:
hid_t gcpl_id | IN: Group or file creation property list identifier |
unsigned crt_order_flags | IN: Creation order flag(s) |
Description:
H5P_SET_LINK_CREATION_ORDER sets flags for tracking and indexing links on creation order in groups created with the group (or file) creation property list gcpl_id.
crt_order_flags contains flags with the following meanings:
H5P_CRT_ORDER_TRACKED | Link creation order is tracked but not necessarily indexed |
H5P_CRT_ORDER_INDEXED | Link creation order is indexed (requires H5P_CRT_ORDER_TRACKED) |
The default behavior is that links are tracked and indexed by name, and link creation order is neither tracked nor indexed. The name is always the primary index for links in a group.
H5P_SET_LINK_CREATION_ORDER can be used to set link creation order tracking, or to set link creation order tracking and indexing.
If (H5P_CRT_ORDER_TRACKED | H5P_CRT_ORDER_INDEXED) is specified for crt_order_flags, then links will be tracked and indexed by creation order. The creation order is added as a secondary index and enables faster queries and iterations by creation order.
If just H5P_CRT_ORDER_TRACKED is specified for crt_order_flags, then links will be tracked by creation order, but not indexed by creation order. Queries and iterations by creation order will work but will be much slower for large groups than if H5P_CRT_ORDER_INDEXED had been included.
Note that if a creation order index is to be built, it must be specified in the group creation property list. HDF5 currently provides no mechanism to turn on link creation order tracking at group creation time and to build the index later.
Returns:
Returns a non-negative value if successful; otherwise returns a negative value.
Example:
Include Bitbucket Server for Confluence: An error occured
Connection to Bitbucket Server could not be established. Verify that you have properly configured the Bitbucket Server application link for your Confluence space and that your Bitbucket Server instance is up and running. Error details: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
