toString 

public toString(): string

Returns a string representation of this construct.

synthesize 

public synthesize(session: ISynthesisSession): void

Allows this construct to emit artifacts into the cloud assembly during synthesis.

This method is usually implemented by framework-level constructs such as Stack and Asset as they participate in synthesizing the cloud assembly.

sessionRequired

  • Type: @alicloud/ros-cdk-core.ISynthesisSession

The synthesis session.

overrideLogicalId 

public overrideLogicalId(newLogicalId: string): void

Overrides the auto-generated logical ID with a specific ID.

newLogicalIdRequired

  • Type: string

The new logical ID to use for this stack element.

addCondition 

public addCondition(con: RosCondition): void

conRequired

  • Type: @alicloud/ros-cdk-core.RosCondition

addCount 

public addCount(count: number | IResolvable): void

countRequired

  • Type: number | @alicloud/ros-cdk-core.IResolvable

addDeletionOverride 

public addDeletionOverride(path: string): void

Syntactic sugar for addOverride(path, undefined).

pathRequired

  • Type: string

The path of the value to delete.

addDependsOn 

public addDependsOn(target: RosResource): void

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

targetRequired

  • Type: @alicloud/ros-cdk-core.RosResource

addDesc 

public addDesc(desc: string): void

descRequired

  • Type: string

addMetaData 

public addMetaData(key: string, value: any): void

keyRequired

  • Type: string

valueRequired

  • Type: any

addOverride 

public addOverride(path: string, value: any): void

Adds an override to the synthesized ROS resource.

To add a property override, either use addPropertyOverride or prefix path with "Properties." (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

For example,

addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute'])
addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE')

would add the overrides

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}

pathRequired

  • Type: string

The path of the property, you can use dot notation to override values in complex types.

Any intermdediate keys will be created as needed.

valueRequired

  • Type: any

The value.

Could be primitive or complex.

addPropertyDeletionOverride 

public addPropertyDeletionOverride(propertyPath: string): void

Adds an override that deletes the value of a property from the resource definition.

propertyPathRequired

  • Type: string

The path to the property.

addPropertyOverride 

public addPropertyOverride(propertyPath: string, value: any): void

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

propertyPathRequired

  • Type: string

The path of the property.

valueRequired

  • Type: any

The value.

addRosDependency 

public addRosDependency(target: string): void

targetRequired

  • Type: string

applyRemovalPolicy 

public applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): void

Sets the deletion policy of the resource based on the removal policy specified.

optionsOptional

  • Type: @alicloud/ros-cdk-core.RemovalPolicyOptions

getAtt 

public getAtt(attributeName: string): Reference

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

attributeNameRequired

  • Type: string

The name of the attribute.
