# ConnectorContext Class

## ConnectorContext

The [ConnectorContext](https://github.com/Sunbird-Obsrv/connector-sdk-scala/blob/main/connector-sdk-core/src/main/scala/org/sunbird/obsrv/connector/model/Models.scala) class is a part of the `org.sunbird.obsrv.connector.model` package. It encapsulates the context information for a connector instance, including its configuration, state, and statistics. This class is essential for managing the lifecycle and execution of connector instances within the Obsrv platform.

### Class Definition

```scala
package org.sunbird.obsrv.connector.model

import com.fasterxml.jackson.annotation.{JsonIgnore, JsonProperty}
import org.sunbird.obsrv.job.model.Models.ErrorData

object Models {

  case class ConnectorContext(
     @JsonProperty("connector_id") connectorId: String,
     @JsonProperty("dataset_id") datasetId: String,
     @JsonProperty("connector_instance_id") connectorInstanceId: String,
     @JsonProperty("connector_type") connectorType: String,
     @JsonIgnore entryTopic: String,
     @JsonIgnore state: ConnectorState,
     @JsonIgnore stats: ConnectorStats
   )
}
```

### Fields

#### `connectorId: String`

* **Description**: The unique identifier for the connector.
* **Annotations**: `@JsonProperty("connector_id")`

#### `datasetId: String`

* **Description**: The unique identifier for the dataset associated with the connector.
* **Annotations**: `@JsonProperty("dataset_id")`

#### `connectorInstanceId: String`

* **Description**: The unique identifier for the specific instance of the connector.
* **Annotations**: `@JsonProperty("connector_instance_id")`

#### `connectorType: String`

* **Description**: The type of the connector (e.g., source, sink).
* **Annotations**: `@JsonProperty("connector_type")`

#### `entryTopic: String`

* **Description**: The entry topic for the connector. This field is ignored during JSON serialization.
* **Annotations**: `@JsonIgnore`

#### [state: ConnectorState](https://github.com/Sunbird-Obsrv/connector-sdk-scala/blob/main/connector-sdk-core/src/main/scala/org/sunbird/obsrv/connector/model/ConnectorState.scala)

* **Description**: The state of the connector instance, encapsulated in a [ConnectorState](https://vscode-file/vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-sandbox/workbench/workbench.html) object. This field is ignored during JSON serialization.
* **Annotations**: `@JsonIgnore`

#### [stats: ConnectorStats](https://github.com/Sunbird-Obsrv/connector-sdk-scala/blob/main/connector-sdk-core/src/main/scala/org/sunbird/obsrv/connector/model/ConnectorStats.scala)

* **Description**: The statistics of the connector instance, encapsulated in a [ConnectorStats](https://vscode-file/vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-sandbox/workbench/workbench.html) object. This field is ignored during JSON serialization.
* **Annotations**: `@JsonIgnore`

### Usage

The ConnectorContext class is used to manage and track the state and statistics of a connector instance. It provides a structured way to access and manipulate the context information required for the execution of connectors.

#### Example

```scala
import org.sunbird.obsrv.connector.model.Models.ConnectorContext
import org.sunbird.obsrv.connector.model.{ConnectorState, ConnectorStats}
import org.sunbird.obsrv.job.util.PostgresConnectionConfig

implicit val postgresConfig: PostgresConnectionConfig = // initialize config

val state = new ConnectorState("connectorInstanceId", None)
val stats = new ConnectorStats("connectorInstanceId", None)

val context = ConnectorContext(
  connectorId = "connectorId",
  datasetId = "datasetId",
  connectorInstanceId = "connectorInstanceId",
  connectorType = "source",
  entryTopic = "entryTopic",
  state = state,
  stats = stats
)

// Accessing context fields
println(context.connectorId)
println(context.datasetId)
```

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://obsrv.sunbird.org/guides/connectors-developer-guide/classes/connectorcontext-class.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
