List of available actions

Some common actions need a clear contract so they are defined as API first-class citizen. For example, this is the case for wizards or health checks. Here is the list of the available actions:

Dynamic Values

Mark a method as being useful to fill potential values of a string option for a property denoted by its value. You can link a field as being completable using @Proposable(value). The resolution of the completion action is then done through the component family and value of the action. The callback doesn’t take any parameter.

  • Type: dynamic_values

  • API: @org.talend.sdk.component.api.service.completion.DynamicValues

  • Returned type: org.talend.sdk.component.api.service.completion.Values

  • Sample:

{
  "items":[
    {
      "id":"value",
      "label":"label"
    }
  ]
}

Healthcheck

This class marks an action doing a connection test

  • Type: healthcheck

  • API: @org.talend.sdk.component.api.service.healthcheck.HealthCheck

  • Returned type: org.talend.sdk.component.api.service.healthcheck.HealthCheckStatus

  • Sample:

{
  "comment":"Something went wrong",
  "status":"KO"
}

Schema

Mark an action as returning a discovered schema. Its parameter MUST be a dataset. Dataset is configuration type annotated with @DataSet. If component has multiple datasets, then dataset used as action parameter should have the same identifier as this @DiscoverSchema.

  • Type: schema

  • API: @org.talend.sdk.component.api.service.schema.DiscoverSchema

  • Returned type: org.talend.sdk.component.api.record.Schema

  • Sample:

{
  "entries":[
    {
      "comment":"The column 1",
      "name":"column1",
      "nullable":false,
      "type":"STRING"
    },
    {
      "comment":"The int column",
      "name":"column2",
      "nullable":false,
      "type":"INT"
    }
  ],
  "type":"RECORD"
}

Suggestions

Mark a method as being useful to fill potential values of a string option. You can link a field as being completable using @Suggestable(value). The resolution of the completion action is then done when the user requests it (generally by clicking on a button or entering the field depending the environment).

  • Type: suggestions

  • API: @org.talend.sdk.component.api.service.completion.Suggestions

  • Returned type: org.talend.sdk.component.api.service.completion.SuggestionValues

  • Sample:

{
  "cacheable":false,
  "items":[
    {
      "id":"value",
      "label":"label"
    }
  ]
}

Update

This class marks an action returning a new instance replacing part of a form/configuration.

  • Type: update

  • API: @org.talend.sdk.component.api.service.update.Update

User

Extension point for custom UI integrations and custom actions.

  • Type: user

  • API: @org.talend.sdk.component.api.service.Action

Validation

Mark a method as being used to validate a configuration.

this is a server validation so only use it if you can’t use other client side validation to implement it.

  • Type: validation

  • API: @org.talend.sdk.component.api.service.asyncvalidation.AsyncValidation

  • Returned type: org.talend.sdk.component.api.service.asyncvalidation.ValidationResult

  • Sample:

{
  "comment":"Something went wrong",
  "status":"KO"
}

Built In Actions

These actions are provided - or not - by the application the UI runs within.

always ensure you don’t require this action in your component.

built_in_suggestable

Mark the decorated field as supporting suggestions, i.e. dynamically get a list of valid values the user can use. It is however different from @Suggestable by looking up the implementation in the current application and not the services. Finally, it is important to note that it can do nothing in some environments too and that there is no guarantee the specified action is supported.
