Specified by:

init in interface SolrRequestHandler

Overrides:

init in class RequestHandlerBase

Parameters:

args - The NamedList to initialize from

initializeMetrics

public void initializeMetrics(SolrMetricsContext parentContext,
                              String scope)

Description copied from interface: SolrMetricProducer

Initialize metrics specific to this producer.

Specified by:

initializeMetrics in interface SolrMetricProducer

Overrides:

initializeMetrics in class RequestHandlerBase

Parameters:

parentContext - parent metrics context. If this component has the same life-cycle as the parent it can simply use the parent context, otherwise it should obtain a child context using SolrMetricsContext.getChildContext(Object) passing this as the child object.

scope - component scope

registerV2

public Boolean registerV2()

Description copied from interface: ApiSupport

Whether this request handler must be made available at the /v2/ path

Specified by:

registerV2 in interface ApiSupport

registerCustomActions

public final void registerCustomActions(Map<String,CoreAdminHandler.CoreAdminOp> customActions)

Registers custom actions defined in solr.xml. Called from the CoreContainer during load process.

Parameters:

customActions - to register

Throws:

org.apache.solr.common.SolrException - in case of action with indicated name is already registered

getCoreContainer

public CoreContainer getCoreContainer()

The instance of CoreContainer this handler handles. This should be the CoreContainer instance that created this handler.

Returns:

a CoreContainer instance

getCoreAdminAsyncTracker

public CoreAdminHandler.CoreAdminAsyncTracker getCoreAdminAsyncTracker()

The instance of CoreAdminAsyncTracker owned by this handler.

Returns:

a CoreAdminHandler.CoreAdminAsyncTracker instance.

handleRequestBody

public void handleRequestBody(SolrQueryRequest req,
                              SolrQueryResponse rsp)
                       throws Exception

Specified by:

handleRequestBody in class RequestHandlerBase

Throws:

Exception

handleCustomAction

@Deprecated
protected void handleCustomAction(SolrQueryRequest req,
                                  SolrQueryResponse rsp)

Deprecated.

Use actions defined via solr.xml instead.

Handle Custom Action.

This method could be overridden by derived classes to handle custom actions.
By default - this method throws a solr exception. Derived classes are free to write their derivation if necessary.
