LogActor

The LogActor is a Coral Actor that logs the received trigger JSON object. The actor can write incoming messages to a file or it can send them to the same log as where Coral platform log messages are written to (by default, this is standard out). This is useful for debugging purposes.

Creating a LogActor

The LogActor has "type": "log". The params value is optional and has the following fields:

field	type	required	description
`file`	string	no	location of the file to log to. If not provided, the log settings of the platform are used.
`append`	boolean	no	when true, the actor appends to a possibily existing file, otherwise a possibly existing the file is overwritten.

Example

{
  "type": "log",
  "params": {
    "file": "/tmp/coral.log",
    "append": true
  }
}

This will create a log actor that appends the received trigger JSON to the file /tmp/coral.log. If no params value is given, the log settings of the Coral platform will be used:

{
  "type": "log"
}

By default, this means that JSON objects will then be sent to standard out.

Trigger

The LogActor only does useful work if JSON objects come in through its trigger.

Emit

The LogActor emits nothing. Conceptually, writing the trigger message to file or to a log can be thought of as an emit.

State

The LogActor does not keep state.

Collect

The LogActor does not collect state from other actors.

Timer

The LogActor does not provide timer actions.
