org.pgpainless.signature.cleartext_signatures.WriteToFileMultiPassStrategy

All Implemented Interfaces:

MultiPassStrategy

public class WriteToFileMultiPassStrategy
extends java.lang.Object
implements MultiPassStrategy

Implementation of the MultiPassStrategy. When processing signed data the first time, the data is being written out into a file. For the second pass, that file is being read again. This strategy is recommended when larger amounts of data need to be processed. For smaller files, InMemoryMultiPassStrategy yields higher efficiency.

Constructor Detail

WriteToFileMultiPassStrategy

public WriteToFileMultiPassStrategy(java.io.File file)

Create a MultiPassStrategy which writes data to a file. Note that getMessageOutputStream() will create the file if necessary.

Parameters:

file - file to write the data to and read from

Method Detail

getMessageOutputStream

public java.io.OutputStream getMessageOutputStream()
                                            throws java.io.IOException

Description copied from interface: MultiPassStrategy

Provide an OutputStream into which the signed data can be read into.

Specified by:

getMessageOutputStream in interface MultiPassStrategy

Returns:

output stream

Throws:

java.io.IOException - io error

getMessageInputStream

public java.io.InputStream getMessageInputStream()
                                          throws java.io.IOException

Description copied from interface: MultiPassStrategy

Provide an InputStream which contains the data that was previously written away in MultiPassStrategy.getMessageOutputStream(). As there may be multiple signatures that need to be processed, each call of this method MUST return a new InputStream.

Specified by:

getMessageInputStream in interface MultiPassStrategy

Returns:

input stream

Throws:

java.io.IOException - io error
