[jira] [Commented] (HELIX-98) clean up setting constraint api

["Kanak Biscuitwala (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HELIX-98?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13770994#comment-13770994 ] 

Kanak Biscuitwala commented on HELIX-98:
----------------------------------------

Resolving this by adding addStateConstraint and addTransitionConstraint to the ClusterConfig builder for the new API. Also added new builders for state and message types that wrap the existing builder.

> currently setting constraint is doing through the following api:
> 1) constraint builder
> builder.addConstraintAttribute(key1, value1).addConstraintAttribute(key2, value2)....
> 2) add constraint to cluster
> admin.addConstraint(clusterName, constraintType, constraintId, constraint)
> will be better to have:
> 1) builder(id).forMsgType(msgType).forInstance(instanceName).setConstraint(contraintValue)
> 2) add constraint to cluster
> admin.addMsgConstraint(clusterName, constraint)
