Syntax

typedef enum CF_OPERATION_TYPE {
  CF_OPERATION_TYPE_TRANSFER_DATA,
  CF_OPERATION_TYPE_RETRIEVE_DATA,
  CF_OPERATION_TYPE_ACK_DATA,
  CF_OPERATION_TYPE_RESTART_HYDRATION,
  CF_OPERATION_TYPE_TRANSFER_PLACEHOLDERS,
  CF_OPERATION_TYPE_ACK_DEHYDRATE,
  CF_OPERATION_TYPE_ACK_DELETE,
  CF_OPERATION_TYPE_ACK_RENAME
} ;

Constants

CF_OPERATION_TYPE_TRANSFER_DATA A sync provider performs TRANSFER_DATA to hydrate a placeholder file. This operation can be performed as a response to a FETCH_DATA callback, a VALIDATE_DATA callback, or as part of a preemptive background hydration effort outside of any callback context.
CF_OPERATION_TYPE_RETRIEVE_DATA A sync provider performs a RETRIEVE_DATA operation as part of the placeholder hydration in order to validate the integrity of the data that was previously transferred to the placeholder. This operation can be performed as a response to a FETCH_DATA callback, a VALIDATE_DATA callback, or as part of a preemptive background hydration effort outside of any callback context.
CF_OPERATION_TYPE_ACK_DATA A sync provider performs a ACK_DATA operation as part of the placeholder hydration after validating the integrity of the data that was previously transferred to the platform. This operation can be performed as a response to a FETCH_DATA callback, a VALIDATE_DATA callback, or as part of a preemptive background hydration effort outside of any callback context
CF_OPERATION_TYPE_RESTART_HYDRATION A sync provider performs a RESTART_HYDRATION operation to restart an ongoing hydration. This operation can be performed as a response to a FETCH_DATA callback, a VALIDATE_DATA callback, or as part of a preemptive background hydration effort outside of any callback context.
CF_OPERATION_TYPE_TRANSFER_PLACEHOLDERS Transfers placeholders. The sync provider must transfer all placeholders matching the pattern but not necessarily in one-shot, as a minimum requirement. The sync provider may additionally choose to transfer placeholders not matching the pattern.
CF_OPERATION_TYPE_ACK_DEHYDRATE Acknowledge and dehydrate a placeholder.
CF_OPERATION_TYPE_ACK_DELETE Acknowledge and delete a placeholder.
CF_OPERATION_TYPE_ACK_RENAME Acknowledge and rename a placeholder.
