                                           PolicySet policySet,
                                           List<PolicyDeploymentStatus> deploymentStatuses)

Check whether the API can be unblocked after a fresh PolicySet has been applied to it

Specified by:

onPolicySetDeploymentCompleted in interface PolicySetDeploymentListener

Parameters:

apiKey - key of the API

policySet - set of policies that were deployed

deploymentStatuses - statuses of policies that were deployed

onContractsLoaded

public void onContractsLoaded(com.mulesoft.mule.runtime.gw.api.key.ApiKey apiKey)

Updates the gatekeeper status to indicate that contracts where correctly loaded.

Specified by:

onContractsLoaded in interface ApiContractsListener

onNoContractsRequired in interface ApiContractsListener

getMonitoredApi

protected Optional<Api> getMonitoredApi(com.mulesoft.mule.runtime.gw.api.key.ApiKey apiKey)

Parameters:

apiKey - the key of the API to retrieve.

Returns:

the API corresponding to the apiKey if fulfills the requirements for the Gatekeeper to observe it, or Optional.empty() otherwise.

getBlockedMonitoredApi

protected Optional<Api> getBlockedMonitoredApi(com.mulesoft.mule.runtime.gw.api.key.ApiKey apiKey)

Parameters:

apiKey - the key of the API to retrieve.

Returns:

@return the API corresponding to the apiKey if it fulfills the requirements for the Gatekeeper to observe it has not yet been unblocked.

everyPolicySuccessfullyApplied

                                                 List<PolicyDeploymentStatus> deploymentStatuses)

validOrigin

protected abstract boolean validOrigin(PolicySet set)

Parameters:

set - PolicySet who's origin needs to be checked.

Returns:

true if the origin of the policy set is valid for the gatekeeper configuration.

isMonitored

protected abstract boolean isMonitored(Api api)

blockApi

protected abstract void blockApi(Api api)

unblockApi

protected abstract void unblockApi(Api api)

onApiDeploymentStart

public void onApiDeploymentStart(Api api)
