Method Detail

finalizeProperties

public TreeNode<Set<String>> finalizeProperties(TreeNode<QueryInfo> queryProperties,
                                                boolean isCollection)

Description copied from interface: Renderer

Finalize which properties are requested by the query. This is called once per user query regardless of how many sub-queries the original query is decomposed into.

Specified by:

finalizeProperties in interface Renderer

Parameters:

queryProperties - tree of query information. Contains query information for the root query and all sub-queries (children)

isCollection - whether the query is a collection

Returns:

tree of sets of string properties for each query including any sub-queries

finalizeResult

public Result finalizeResult(Result queryResult)

Description copied from interface: Renderer

Finalize the query results.

Specified by:

finalizeResult in interface Renderer

Parameters:

queryResult - result of query in native (default) format

Returns:

result in the format dictated by the renderer

getResultPostProcessor

public ResultPostProcessor getResultPostProcessor(Request request)

Description copied from interface: Renderer

Obtain the associated post processor. Post Processors existed prior to renderer's to allow the native result to be augmented before returning it to the user. This functionality should be merged into the renderer.

Specified by:

getResultPostProcessor in interface Renderer

Parameters:

request - original request

Returns:

associated post processor

requiresPropertyProviderInput

public boolean requiresPropertyProviderInput()

Description copied from interface: Renderer

Obtains the property provider requirements of the given renderer implementation.

Specified by:

requiresPropertyProviderInput in interface Renderer

Overrides:

requiresPropertyProviderInput in class BaseRenderer

Returns:

true if property provider support is required false if property provider support is not required

createClusterTopology

protected ClusterTopology createClusterTopology(TreeNode<Resource> clusterNode)
                                         throws InvalidTopologyTemplateException,
                                                InvalidTopologyException

Throws:

InvalidTopologyTemplateException

InvalidTopologyException

getController

protected AmbariManagementController getController()

Get management controller instance.

Returns:

management controller
