end

Instance Method Details

#apply_cross_stack_reference_strength(strength) ⇒ void

This method returns an undefined value.

Override the cross-stack reference strength for this resource.

When set, any cross-stack reference to this resource will use the specified mechanism instead of the global default determined by the @aws-cdk/core:defaultCrossStackReferences context key. This is useful for selectively weakening specific references to avoid the "deadly embrace" problem without changing the app-wide default.

Parameters:

# File 'app_sync/appsync_function.rb', line 176

def apply_cross_stack_reference_strength(strength)
  Jsii::Type.check_type(strength, JSON.parse(Base64.strict_decode64("eyJmcW4iOiJhd3MtY2RrLWxpYi5SZWZlcmVuY2VTdHJlbmd0aCJ9")), "strength")
  jsii_call_method("applyCrossStackReferenceStrength", [strength])
end

#apply_removal_policy(policy) ⇒ void

This method returns an undefined value.

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).

Parameters:

  Jsii::Type.check_type(policy, JSON.parse(Base64.strict_decode64("eyJmcW4iOiJhd3MtY2RrLWxpYi5SZW1vdmFsUG9saWN5In0=")), "policy")
  jsii_call_method("applyRemovalPolicy", [policy])
end

#data_source ⇒ AWSCDK::AppSync::BaseDataSource

the data source of this AppSync Function.

Returns:

113
 
# File 'app_sync/appsync_function.rb', line 111

def data_source()
  jsii_get_property("dataSource")
end

#env ⇒ AWSCDK::Interfaces::ResourceEnvironment

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.

Returns:

# File 'app_sync/appsync_function.rb', line 76

def env()
  jsii_get_property("env")

#function_arn ⇒ String

def function_arn()

#function_configuration_ref ⇒ AWSCDK::Interfaces::AWSAppsync::FunctionConfigurationReference

A reference to a FunctionConfiguration resource.

Returns:

# File 'app_sync/appsync_function.rb', line 199

def generate_physical_name()
  jsii_call_method("generatePhysicalName", [])
end

#get_resource_arn_attribute(arn_attr, arn_components) ⇒ String

Returns an environment-sensitive token that should be used for the resource's "ARN" attribute (e.g. bucket.bucketArn).

Normally, this token will resolve to arn_attr, but if the resource is referenced across environments, arn_components will be used to synthesize a concrete ARN with the resource's physical name. Make sure to reference this.physicalName in arn_components.

Parameters:

  • arn_attr (String) —

    The CFN attribute which resolves to the ARN of the resource.

  • arn_components (AWSCDK::ARNComponents) —

    The format of the ARN of this resource.

Returns:

  • (String)

  jsii_call_method("getResourceArnAttribute", [arn_attr, arn_components])
end

#get_resource_name_attribute(name_attr) ⇒ String

Returns an environment-sensitive token that should be used for the resource's "name" attribute (e.g. bucket.bucketName).

Normally, this token will resolve to name_attr, but if the resource is referenced across environments, it will be resolved to this.physicalName, which will be a concrete name.

Parameters:

  • name_attr (String) —

    The CFN attribute which resolves to the resource's name.

Returns:

  • (String)

def node()

end

#physical_name ⇒ String

Returns a string-encoded token that resolves to the physical name that should be passed to the CloudFormation resource.

This value will resolve to one of the following:

  • a concrete value (e.g. "my-awesome-bucket")
  • undefined, when a name should be generated by CloudFormation
  • a concrete name generated automatically during synthesis, in cross-environment scenarios.

Returns:

  • (String)

end

#with(*mixins) ⇒ Constructs::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. Use multiple with() calls if subsequent mixins should apply to added constructs.

Parameters:

  • mixins (Array<Constructs::IMixin>)

Returns:

  • (Constructs::IConstruct)
