Validations

Validations help restricting what can be entered or selected in an input field, to make sure that the value complies with the expected type of information.

Property validation

/** configuration class */
@Option
@Validable("url")
String config;

/** service class */
@AsyncValidation("url")
ValidationResult doValidate(String url) {
//validate the property
}
Studio Rendering Web Rendering

Property validation with Pattern

/** configuration class */
@Option
@Pattern("/^[a-zA-Z\\-]+$/")
String username;
Studio Rendering Web Rendering

Web Code

Data store validation

@Datastore
@Checkable
public class config {
/** config ...*/
}

/** service class */
@HealthCheck
public HealthCheckStatus testConnection(){

//validate the connection
}
Studio Rendering Web Rendering
Studio Code
Web Code

You can also use other types of validation that are similar to @Pattern:

  • @Min, @Max for numbers.

  • @Unique for collection values.

  • @Required for a required configuration.

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.

  • API: @org.talend.sdk.component.api.configuration.action.BuiltInSuggestable

Conditions

ActiveIf

If the evaluation of the element at the location matches value then the element is considered active, otherwise it is deactivated.

  • API: @org.talend.sdk.component.api.configuration.condition.ActiveIf

  • Type: if

  • Sample:

{
  "condition::if::evaluationStrategy":"DEFAULT",
  "condition::if::negate":"false",
  "condition::if::target":"test",
  "condition::if::value":"value1,value2"
}

ActiveIfs

Allows to set multiple visibility conditions on the same property.

  • API: @org.talend.sdk.component.api.configuration.condition.ActiveIfs

  • Type: ifs

  • Sample:

{
  "condition::if::evaluationStrategy::0":"DEFAULT",
  "condition::if::evaluationStrategy::1":"LENGTH",
  "condition::if::negate::0":"false",
  "condition::if::negate::1":"true",
  "condition::if::target::0":"sibling1",
  "condition::if::target::1":"../../other",
  "condition::if::value::0":"value1,value2",
  "condition::if::value::1":"SELECTED",
  "condition::ifs::operator":"AND"
}

Configuration types

Dataset

Mark a model (complex object) as being a dataset.

  • API: @org.talend.sdk.component.api.configuration.type.DataSet

  • Sample:

{
  "tcomp::configurationtype::name":"test",

Package Scanning

Since the framework can be used in the case of fatjars or shades, and because it still uses scanning, it is important to ensure we don’t scan the whole classes for performances reason.

it is not recommanded but possible to add in your plugin module a TALEND-INF/scanning.properties file with classloader.includes and classloader.excludes entries to refine the scanning with custom rules. In such a case, exclusions win over inclusions.

Server configuration

the configuration is read from system properties, environment variables, …​.
talend.component.server.component.coordinates

A comma separated list of gav to locate the components

talend.component.server.component.documentation.translations

Default value: ${home}/documentations. A component translation repository. This is where you put your documentation translations. Their name must follow the pattern documentation_${container-id}_language.adoc where ${container-id} is the component jar name (without the extension and version, generally the artifactId).

talend.component.server.component.extend.dependencies

Default value: true. Should the component extensions add required dependencies.

talend.component.server.component.registry

A property file where the value is a gav of a component to register (complementary with coordinates)

talend.component.server.documentation.active

Default value: true. Should the /documentation endpoint be activated. Note that when called on localhost the doc is always available.

talend.component.server.environment.active

Default value: true. Should the /api/v1/environment endpoint be activated. It shows some internal versions and git commit which are not always desirable over the wire.

talend.component.server.filter.secured.tokens

Default value: -. Accepted tokens in Authorization header for remote calls to secured endpoints (/api/v1/environment or /documentation).

talend.component.server.jaxrs.exceptionhandler.defaultMessage

Default value: false. If set it will replace any message for exceptions. Set to false to use the actual exception message.

talend.component.server.maven.repository

The local maven repository used to locate components and their dependencies

talend.component.server.security.command.handler

Default value: securityNoopHandler. How to validate a command/request. Accepted values: securityNoopHandler.

talend.component.server.security.connection.handler

Default value: securityNoopHandler. How to validate a connection. Accepted values: securityNoopHandler.

talend.component.server.user.extensions.location

A folder available for the server - don’t forget to mount it in docker if you are using the image - which accepts subfolders named as component plugin id (generally the artifactId or jar name without the version, ex: jdbc). Each family folder can contain:

  • a user-configuration.properties file which will be merged with component configuration system (see services). This properties file enables the function userJar(xxxx) to replace the jar named xxxx by its virtual gav (groupId:artifactId:version),

  • a list of jars which will be merged with component family classpath

talend.component.server.user.extensions.provisioning.location

Default value: auto. Should the implicit artifacts be provisionned to a m2. If set to auto it tries to detect if there is a m2 to provision - recommended, if set to skip it is ignored, else it uses the value as a m2 path.
