---

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.

session^Required

• 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.

newLogicalId^Required

• Type: java.lang.String

The new logical ID to use for this stack element.

---

addCondition

public void addCondition(RosCondition con)

con^Required

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

---

addCount

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

count^Required

• 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).

path^Required

• 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.

target^Required

---

addDesc

• 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"
       ...
     },
   ]
   ...
}

path^Required

The value.

Could be primitive or complex.

---

addPropertyDeletionOverride
