Since IPCDataTransfer* is actually used for nsITransferable, so rename them to IPCTransferable* as follows, - Rename IPCDataTransfer to IPCTransferableData. - Rename IPCDataTransferItem to IPCTransferableDataItem. - Rename IPCDataTransferData to IPCTransferableDataType. - Rename IPCDataTransferString to IPCTransferableDataString. - Rename IPCDataTransferCString to IPCTransferableDataCString. - Rename IPCDataTransferInputStream to IPCTransferableDataInputStream. - Rename IPCDataTransferImageContainer to IPCTransferableDataImageContainer. - Rename IPCDataTransferBlob to IPCTransferableDataBlob.
