Method Detail

process

public java.lang.Object process(java.lang.String method,

                       Record inputRecord)

process input record and return result object. Override this method in your handler if you do not need access to HttpExchange object, e.g. to read http header fields. Otherwise use overloaded method with HttpExchange parameter.

Overrides:

process in class JsonRequestHandler

Parameters:

method - HTTP method

requestUri - request URI.

inputRecord - input record parsed either from request body, if it has content, or from request URI parameters.

Returns:

result object, may be null. If this is not a Record, you have to provide a JsonRequestHandler.writeResultObject(OutputStream, Object) method, too.

setWorkerManager

public void setWorkerManager(WorkerManager wm)

Parameters:

wm - new WorkerManager to set

unsetWorkerManager

public void unsetWorkerManager(WorkerManager wm)

Parameters:

wm - new WorkerManager to remove

setClusterConfigService

public void setClusterConfigService(ClusterConfigService clusterConfigService)

set new ClusterConfigService. To be called by DS runtime before activation.

Parameters:

clusterConfigService - new ClusterConfigService

unsetClusterConfigService

public void unsetClusterConfigService(ClusterConfigService clusterConfigService)

remove a ClusterConfigService. To be called by DS runtime after deactivation.

setZooKeeperService

public void setZooKeeperService(ZooKeeperService zkService)

method for DS to set a service reference.

Parameters:

zkService - ZooKeeperService reference.

unsetZooKeeperService

public void unsetZooKeeperService(ZooKeeperService zkService)

method for DS to unset a service reference.

Parameters:

zkService - ZooKeeperService reference.

isValidMethod

protected boolean isValidMethod(java.lang.String method,
                    java.lang.String requestUri)

Checks if the handler allows the HTTP method. GET is currently the only valid method.

Overrides:

isValidMethod in class JsonRequestHandler

Parameters:
