temporal functions (Temporal)

This module contains the functions used to insert, delete and manage temporal documents.

To understand the temporal functions, you need to understand the meaning of the following terms:

The Tiered Storage function module is installed as the following file:

32 functions
Function name Description
temporal:advance-lsqt This function enables Last Stable Query Time (LSQT) on the named collection and advances the LSQT for the collection to the maximum system start time.
temporal:axes This function returns all the axis names defined in the schema databases.
temporal:axis-create This function constructs an axis definition based on the existing range indexes that can be added to a temporal collection in subsequent API calls.
temporal:axis-get-end This function returns the range index used to define the end of the period by the named axis.
temporal:axis-get-start This function returns the range index used to define the start of the period by the named axis.
temporal:axis-remove This function removes an axis definition from the schema database.
temporal:collection-create This function constructs a named and protected temporal collection in the schema database with the specified system and optional valid axes.
temporal:collection-get-axis This function returns the name of either the system or valid axis in the named temporal collection.
temporal:collection-get-options This function returns the options set on the temporal collection.
temporal:collection-remove This function removes the named temporal collection from the Schemas database.
temporal:collection-set-options This function sets the options on the temporal collection.
temporal:collections This function returns all of the temporal collection names in the schema database.
temporal:document-delete This function deletes the temporal document identified by the given URI.
temporal:document-insert This function inserts a document into the database and stores it as a temporal document.
temporal:document-load This function inserts a document into the database and stores it as a temporal document.
temporal:document-protect Protects a temporal document from certain temporal operations, such as update, delete or wipe for a specific period of time.
temporal:document-wipe Deletes all versions of a temporal document.
temporal:get-lsqt This function returns the Last Stable Query Time (LSQT) for the collection at current moment.
temporal:get-lsqt-automation This function returns whether Last Stable Query Time (LSQT) management is automatically managed (true) or not automatically managed (false).
temporal:get-lsqt-automation-lag When the LSQT is advanced automatically, this function returns how far behind (in milliseconds) the Last Stable Query Time (LSQT) is from latest system time.
temporal:get-lsqt-automation-period This function returns how often Last Stable Query Time (LSQT) is automatically advanced, in milliseconds.
temporal:get-use-lsqt This function specifies whether the named temporal collection has LSQT (Last Stable Query Time) enabled (true) or disabled (false).
temporal:node-delete Deletes a node from the database.
temporal:node-insert-after Adds an immediately following sibling to a node in a temporal document.
temporal:node-insert-before Adds an immediately preceding sibling to a node in a temporal document.
temporal:node-insert-child Adds a new last child to a node in a temporal document.
temporal:node-replace Replaces a node in a temporal document.
temporal:set-lsqt-automation This function sets whether Last Stable Query Time (LSQT) management is automatic.
temporal:set-use-lsqt This function enables or disables the use of LSQT (Last Stable Query Time) on the named collection.
temporal:statement-get-system-time This function gets the system start time on temporal documents that are inserted or deleted in the same statement as this function.
temporal:statement-set-document-version-uri This function sets document URI for a temporal document to be used for the new version of temporal document to be generated in the current statement.
temporal:statement-set-system-time This function sets the system start time on temporal documents that are inserted or deleted in the same statement as this function.
