toString

public java.lang.String toString()

Returns a string representation of this construct.

synthesize

public void synthesize(ISynthesisSession session)

The synthesis session.


addCondition

public void addCondition(RosCondition condition)

conditionRequired

  • 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

addDependency

public void addDependency(Resource resource)

resourceRequired

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

addResourceDesc

public void addResourceDesc(java.lang.String desc)

descRequired

  • Type: java.lang.String

applyRemovalPolicy

public void applyRemovalPolicy(RemovalPolicy policy)

policyRequired

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

getAtt

public IResolvable getAtt(java.lang.String name)

nameRequired

  • Type: java.lang.String

setMetadata

public void setMetadata(java.lang.String key, java.lang.Object value)

keyRequired

  • Type: java.lang.String

valueRequired

  • Type: java.lang.Object
