Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`T`	`getParameters()`	Return the parameters for this output signer.
`byte[]`	`getSignature()`	Return the signature calculated on what has been written to the calculator's output stream.
`int`	`getSignature(byte[] output, int off)`	Output the signature value for what has been written to the signer's output stream.
`UpdateOutputStream`	`getSigningStream()`	Returns a stream that will accept data for the purpose of calculating a signature.

- Method Detail
  - getParameters
```
T getParameters()
```
    Return the parameters for this output signer.
    
    Returns:
    
    the signer's parameters.
  - getSigningStream
```
UpdateOutputStream getSigningStream()
```
    Returns a stream that will accept data for the purpose of calculating a signature. Use org.bouncycastle.util.io.TeeOutputStream if you want to accumulate the data on the fly as well.
    
    Returns:
    
    an UpdateOutputStream
  - getSignature
```
byte[] getSignature()
             throws PlainInputProcessingException
```
    Return the signature calculated on what has been written to the calculator's output stream.
    
    Returns:
    
    a signature.
    
    Throws:
    
    PlainInputProcessingException - if the input provided cannot be processed.
  - getSignature
```
int getSignature(byte[] output,
                 int off)
          throws PlainInputProcessingException
```
    Output the signature value for what has been written to the signer's output stream.
    
    Parameters:
    
    output - output array to write the signature to.
    
    off - offset to start writing the signature at.
    
    Returns:
    
    the number of bytes output.
    
    Throws:
    
    PlainInputProcessingException - if the input provided cannot be processed.
