Parameters:

algorithm - the URI identifying the signature algorithm

params - algorithm-specific signature parameters (may be null)

Throws:

InvalidAlgorithmParameterException - if the specified parameters are inappropriate for the requested algorithm

NoSuchAlgorithmException - if an implementation of the specified algorithm cannot be found

NullPointerException - if algorithm is null

SignatureMethodImpl

public SignatureMethodImpl(DOMCryptoContext context,

Creates a new instance of this SignatureMethodImpl with the specified context and node to unmarshal from.

Parameters:

context - the marshal context

node - the node to unmarshal from

Throws:

MarshalException - if an exception occurs during unmarshaling
