Example 1 with AZURE_STORAGE_BLOBS

use of com.vmware.photon.controller.model.adapters.azure.constants.AzureConstants.AZURE_STORAGE_BLOBS in project photon-model by vmware.

the class AzureStorageEnumerationAdapterService method disassociateDiskStates.

/*
     * Disassociate local disk states that no longer exist in Azure
     *
     * The logic works by recording a timestamp when enumeration starts. This timestamp is used to
     * lookup resources which haven't been touched as part of current enumeration cycle. The other
     * data point this method uses is the blob discovered as part of get blob call.
     *
     * A disassociate on a disk state is invoked only if it meets two criteria: - Timestamp older
     * than current enumeration cycle. - blob is not present on Azure.
