extractResourceName

@Nullable
protected String extractResourceName(com.google.protobuf.Message unpackedResource)

Description copied from class: XdsResourceType

Extract the resource name from an older resource type that included the name within the resource contents itself. The newer approach has resources wrapped with envoy.service.discovery.v3.Resource which then provides the name. This method is only called for the old approach.

Overrides:

extractResourceName in class XdsResourceType<XdsEndpointResource.EdsUpdate>

Returns:

the resource's name, or null if name is not stored within the resource contents

typeName

public String typeName()

Specified by:

typeName in class XdsResourceType<XdsEndpointResource.EdsUpdate>

typeUrl

public String typeUrl()

Specified by:

typeUrl in class XdsResourceType<XdsEndpointResource.EdsUpdate>

shouldRetrieveResourceKeysForArgs

public boolean shouldRetrieveResourceKeysForArgs()

Specified by:

shouldRetrieveResourceKeysForArgs in class XdsResourceType<XdsEndpointResource.EdsUpdate>

isFullStateOfTheWorld

protected boolean isFullStateOfTheWorld()

Specified by:

isFullStateOfTheWorld in class XdsResourceType<XdsEndpointResource.EdsUpdate>

unpackedClassName

protected Class<ClusterLoadAssignment> unpackedClassName()

Specified by:

unpackedClassName in class XdsResourceType<XdsEndpointResource.EdsUpdate>

doParse

protected XdsEndpointResource.EdsUpdate doParse(XdsResourceType.Args args,
 com.google.protobuf.Message unpackedMessage)
                                         throws XdsResourceType.ResourceInvalidException

Specified by:
