Overview
JsonActor
The JsonActor (JSON transformation actor) is a Coral Actor that can transform an input JSON according to a supplied template.
Creating a JsonActor
The creation JSON of the JsonActor (see Coral Actor) has "type": "json".
The params value is a JSON with the following field:
| field | type | required | description |
|---|---|---|---|
template |
JSON | yes | the template for the output |
Example
{
"data": {
"type": "actors",
"attributes": {
"type": "json",
"params": {
"template": {
"a": "some constant text",
"b": "${referenceField}",
"c": "${ref.sub.sub[2]}",
"d": {
"e": "${ref2}",
"f": "${ref3}"
}
}
}
}
}
}If fields are expressions the create a string field starting with a the expression (according to the coral JSON expression parser) surrounded by ${ … }.
Trigger
The JsonActor only does useful work if the trigger is connected.
The trigger can be any JSON. The supplied JSON will be used to fill the template.
Example
Emit
The JsonActor emits the transformed JSON.
That is the template JSON with expressions replaced with their evaluation from the trigger input.
State
The JsonActor keeps no state.
Collect
The JsonActor does not collect state from other actors.
Timer
The JsonActor does not provide timer actions.
