Constructor Detail

DataExchangeFilterOutputStream

public DataExchangeFilterOutputStream(tv.hd3g.transfertfiles.filters.UnaryIOExceptionOperator<OutputStream> streamProvider,
                                      int defaultBufferSize)

DataExchangeFilterOutputStream

public DataExchangeFilterOutputStream(tv.hd3g.transfertfiles.filters.UnaryIOExceptionOperator<OutputStream> streamProvider)

Method Detail

applyDataFilter

public BufferVault applyDataFilter(boolean last,
                                   BufferVault dataSource)
                            throws IOException

Specified by:

applyDataFilter in interface DataExchangeFilter

Parameters:

last - if true, you should use flush/close internal needs and return last responses, because applyDataFilter will never be called for the current instance.

Returns:

empty for "ignore" filter/data collector filter null for stop data transfert operation returned BufferVault can be re-used here after, and can be empty after call

Throws:

IOException

ensureMinDataSourcesDataLength

public int ensureMinDataSourcesDataLength()

Description copied from interface: DataExchangeFilter

Ensure to all applyDataFilter call will contain a total dataSources size equals/more than with this value. Else applyDataFilter with last = true will be called

Specified by:

ensureMinDataSourcesDataLength in interface DataExchangeFilter

Returns:

byte count

onCancelTransfert

public void onCancelTransfert()

Specified by:

onCancelTransfert in interface DataExchangeFilter
