Struct Actions
Struct actions are complex data actions designed to be used with the XINA Structs. Unlike most API actions, they may involve complex multi-step operations, and are dependent on the structs configuration of groups and databases.
Data Actions
STRUCT BUFFER IMPORT
Imports a buffer source file into a model.
| Property | Value | Required | Default |
|---|---|---|---|
| action | "struct_buffer_import" |
yes | |
| model | model group specifier | yes | |
| origin | origin name | yes | |
| object_id | object ID of data file | yes | |
| format | string |
yes | |
| conf | jsonobject |
no | |
| strict_units | boolean |
no | false |
If the mn column is an integer it will be interpretted as a literal mnemonic ID. Otherwise the name will be parsed from this format:
<name>[(<unit>[;n0=v0|n1=v1|...])]
<name> will be used for the mnemonic name lookup. The comparison is case insensitive and any whitespace is treated as a single underscore. <unit> is optional. If provided, it must match the unit of an associated mnemonic definition, otherwise an error is thrown. The section after unit defines discrete value mapping.
When a data set is imported the XINA server will run the following steps:
- For each row:
- validate time and value
- process mnemonic
- If mnemonic ID
- If found in definitions database:
- If mnemonic is deprecated, throw error
- Else, use mnemonic for row
- Else, throw error due to unrecognized ID
- If found in definitions database:
- Else, parse name and optional unit
- If name match found:
- If unit is provided and does not match, throw error
- If mnemonic is deprecated, throw error
- Else, use mnemonic for row
- Else, mnemonic is new, create new temporary mnemonic definition based on provided information
- If name match found:
- If mnemonic ID
- If any rows contain same mnemonic and time, throw error
- Check for time overlap in database
- If found
- If
on_overlap=fail, throw error - Else If
on_overlap=delete, delete all data from database in time range of imported data - Else (
on_overlap=ignore), do nothing
- If
- If found
- If new mnemonic definitions created, insert into mnemonic definition database
- Insert data into mnemonic database
STRUCT MN ALIAS
Adds one or more aliases of name/unit pairs to a single existing mnemonic.
| Property | Value |
|---|---|
action |
"struct_mn_edit" |
database |
mnemonic definition database specifier |
mn |
mnemonic ID |
aliases |
string[], name/unit pair alias(es) for mnemonic |
STRUCT MN EDIT
Edits one or more properties of a single existing mnemonic.
| Property | Value | Required |
|---|---|---|
action |
"struct_mn_edit" |
yes |
database |
mnemonic definition database specifier | yes |
mn |
mnemonic ID | yes |
name |
string, new name/unit pair for mnemonic |
no |
state |
string |
no |
STRUCT MN MERGE
Merges one or more existing mnemonics into a single existing mnemonic.
STRUCT INT OPEN
Opens one or more intervals in a model.
STRUCT INT CLOSE
Closes one or more intervals in a model.
Schema Actions
STRUCT CREATE
The STRUCT CREATE action is used to create a variety of XINA Structs compatible schema elements.
STRUCT CREATE PROJECT
Creates a structs project group.
| Property | Value | Required | Default |
|---|---|---|---|
| action | "struct_create" |
yes | |
| create | "project" |
yes | |
| parent | group specifier | no |
