WriteToFileMultiPassStrategy (PGPainless 1.0.0 API)

java.lang.Object
- org.pgpainless.decryption_verification.cleartext_signatures.WriteToFileMultiPassStrategy

All Implemented Interfaces:

MultiPassStrategy
```
public class WriteToFileMultiPassStrategy
extends 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.

public WriteToFileMultiPassStrategy(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

public OutputStream getMessageOutputStream()
                                    throws 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:
    
    IOException - io error
  - getMessageInputStream
```
public InputStream getMessageInputStream()
                                  throws 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:
    
    IOException - io error
