Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`abstract T`	`getParameters()`	Return the parameters for this output verifier.
`abstract UpdateOutputStream`	`getVerifyingStream()`	Returns a stream that will accept data for the purpose of verifying a previously calculated signature.
`abstract boolean`	`isVerified(byte[] signature)`	Return true if the data written to the verifying stream matches the data the signature was calculated against.

  - getParameters
```
public abstract T getParameters()
```
    Description copied from interface: OutputVerifier
    
    Return the parameters for this output verifier.
    
    Specified by:
    
    getParameters in interface OutputVerifier<T extends Parameters>
    
    Returns:
    
    the verifier's parameters.
  - getVerifyingStream
```
public abstract UpdateOutputStream getVerifyingStream()
```
    Description copied from interface: OutputVerifier
    
    Returns a stream that will accept data for the purpose of verifying a previously calculated signature. Use org.bouncycastle.util.io.TeeOutputStream if you want to accumulate the data on the fly as well.
    
    Specified by:
    
    getVerifyingStream in interface OutputVerifier<T extends Parameters>
    
    Returns:
    
    an UpdateOutputStream
  - isVerified
```
public abstract boolean isVerified(byte[] signature)
                            throws InvalidSignatureException
```
    Description copied from interface: OutputVerifier
    
    Return true if the data written to the verifying stream matches the data the signature was calculated against.
    
    Specified by:
    
    isVerified in interface OutputVerifier<T extends Parameters>
    
    Parameters:
    
    signature - the signature to be confirmed.
    
    Returns:
    
    true if the data verifies against the signature, false otherwise.
    
    Throws:
    
    InvalidSignatureException
