toString 

public java.lang.String toString()

Returns a string representation of this construct.

synthesize 

public void synthesize(ISynthesisSession session)

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: com.aliyun.ros.cdk.core.ISynthesisSession

The synthesis session.

overrideLogicalId 

public void overrideLogicalId(java.lang.String newLogicalId)

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

newLogicalIdRequired

  • Type: java.lang.String

The new logical ID to use for this stack element.

addCondition 

public void addCondition(RosCondition con)

conRequired

  • Type: com.aliyun.ros.cdk.core.RosCondition

addCount 

public void addCount(java.lang.Number OR IResolvable count)

countRequired

  • Type: java.lang.Number OR com.aliyun.ros.cdk.core.IResolvable

addDeletionOverride 

public void addDeletionOverride(java.lang.String path)

Syntactic sugar for addOverride(path, undefined).

pathRequired

  • Type: java.lang.String

The path of the value to delete.

addDependsOn 

public void addDependsOn(RosResource target)

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: com.aliyun.ros.cdk.core.RosResource

addDesc 

public void addDesc(java.lang.String desc)

descRequired

  • Type: java.lang.String

  • Type: java.lang.Object

addOverride 

public void addOverride(java.lang.String path, java.lang.Object value)

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: java.lang.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: java.lang.Object

The value.

Could be primitive or complex.

addPropertyDeletionOverride 

public void addPropertyDeletionOverride(java.lang.String propertyPath)

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

propertyPathRequired

  • Type: java.lang.String

The path to the property.

addPropertyOverride 

public void addPropertyOverride(java.lang.String propertyPath, java.lang.Object value)

Adds an override to a resource property.

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

  • Type: com.aliyun.ros.cdk.core.RemovalPolicyOptions

getAtt 

public Reference getAtt(java.lang.String attributeName)

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: java.lang.String

The name of the attribute.
