# IBridge

Interface for Bridge.

Extends: IBridge
Extends: IResource, IBridgeRef
Implemented by: Bridge

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/bridge.ts`](https://github.com/aws/aws-cdk/blob/v2.276.0-alpha.0/packages/@aws-cdk/aws-mediaconnect-alpha/lib/bridge.ts#L135)

## Properties

- `bridgeArn`: string — The Amazon Resource Name (ARN) of the bridge.

- `bridgeName`: string — The name of the bridge.

- `bridgeRef`: [BridgeReference](/cdk/api/v2/docs/aws-cdk-lib.interfaces.aws_mediaconnect.BridgeReference.html) — A reference to a Bridge resource.

- `bridgeState`: string — The current state of the bridge.

- `bridgeType`: [BridgeType](/cdk/api/v2/docs/@aws-cdk_aws-mediaconnect-alpha.BridgeType.html) — The type of bridge (ingress or egress).

- `env`: [ResourceEnvironment](/cdk/api/v2/docs/aws-cdk-lib.interfaces.ResourceEnvironment.html) — The environment this resource belongs to.

  For resources that are created and managed in a Stack (those created by
  creating new class instances like `new Role()`, `new Bucket()`, etc.), this
  is always the same as the environment of the stack they belong to.

  For referenced resources (those obtained from referencing methods like
  `Role.fromRoleArn()`, `Bucket.fromBucketName()`, etc.), they might be
  different than the stack they were imported into.

- `isFailoverEnabled`: boolean — Failover Configuration for Bridge.

- `node`: [Node](/cdk/api/v2/docs/constructs.Node.html) — The tree node.

- `stack`: [Stack](/cdk/api/v2/docs/aws-cdk-lib.Stack.html) — The stack in which this resource is defined.

## Methods

- `addOutput(id: string, networkOutput: BridgeNetworkOutput): IBridgeOutput` — Add a network output to this bridge (for egress bridges only).

  **Parameters**

  - `id` — Construct id for the new BridgeOutput.
  - `networkOutput` — The named output to add.

- `applyRemovalPolicy(policy: RemovalPolicy): void` — Apply the given removal policy to this resource.

  The Removal Policy controls what happens to this resource when it stops
  being managed by CloudFormation, either because you've removed it from the
  CDK application or because you've made a change that requires the resource
  to be replaced.

  The resource can be deleted (`RemovalPolicy.DESTROY`), or left in your AWS
  account for data recovery and cleanup later (`RemovalPolicy.RETAIN`).

- `metric(metricName: string, props?: MetricOptions): Metric` — Create a CloudWatch metric for this bridge.

  Bridge metrics are dimensioned by `BridgeARN`. See the MediaConnect
  documentation for available metric names (e.g. `IngressBridgeBitRate`,
  `EgressBridgeBitRate`, `IngressBridgePacketLossPercent`).

- `metricFailoverSwitches(props?: MetricOptions): Metric` — Metric for the total number of times the bridge switches between sources when using the `FAILOVER` failover mode.

  Uses `IngressBridgeFailoverSwitches` for ingress bridges and
  `EgressBridgeFailoverSwitches` for egress bridges.

- `metricSourceBitrate(bridgeSourceName: string, props?: MetricOptions): Metric` — Metric for the bitrate of a specific bridge source.

  Uses `IngressBridgeSourceBitRate` for ingress bridges and
  `EgressBridgeSourceBitRate` for egress bridges.

  **Parameters**

  - `bridgeSourceName` — The name of the bridge source.

- `metricSourcePacketLossPercent(bridgeSourceName: string, props?: MetricOptions): Metric` — Metric for the percentage of packets lost on a specific bridge source.

  Uses `IngressBridgeSourcePacketLossPercent` for ingress bridges and
  `EgressBridgeSourcePacketLossPercent` for egress bridges.

  **Parameters**

  - `bridgeSourceName` — The name of the bridge source.

- `with(...mixins: IMixin[]): IConstruct` — Applies one or more mixins to this construct.

  Mixins are applied in order. The list of constructs is captured at the
  start of the call, so constructs added by a mixin will not be visited.

  **Parameters**

  - `mixins` — The mixins to apply.

  **Returns:** This construct for chaining
