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.
- 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.
- Type: java.lang.String
The new logical ID to use for this stack element.
addCondition
public void addCondition(RosCondition con)
- Type: com.aliyun.ros.cdk.core.RosCondition
addCount
public void addCount(java.lang.Number OR IResolvable count)
- 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)
.
- 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.
- Type: com.aliyun.ros.cdk.core.RosResource
addDesc
public void addDesc(java.lang.String desc)
- Type: java.lang.String
addMetaData
public void addMetaData(java.lang.String key, java.lang.Object value)
- 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"
...
},
]
...
}
- 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.
- 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.
- 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: java.lang.String
The path of the property.
- Type: java.lang.Object
The value.

public void applyRemovalPolicy(RemovalPolicy policy, RemovalPolicyOptions options)
Sets the deletion policy of the resource based on the removal policy specified.

Ideally, use generated attribute accessors (e.g. resource.arn
), but this can be used for future compatibility
in case there is no generated attribute.
- Type: java.lang.String
The name of the attribute.
Static Functions
