Methods Summary
public java.security.spec.AlgorithmParameterSpec	getParameterSpec() Returns the algorithm-specific input parameters associated with this Transform. The returned parameters can be typecast to a {@link TransformParameterSpec} object. return the algorithm-specific input parameters (may be null if not specified)
public abstract javax.xml.crypto.Data	transform(javax.xml.crypto.Data data, javax.xml.crypto.XMLCryptoContext context) Transforms the specified data using the underlying transform algorithm. param data the data to be transformed param context the XMLCryptoContext containing additional context (may be null if not applicable) return the transformed data throws NullPointerException if data is null throws TransformException if an error occurs while executing the transform
public abstract javax.xml.crypto.Data	transform(javax.xml.crypto.Data data, javax.xml.crypto.XMLCryptoContext context, java.io.OutputStream os) Transforms the specified data using the underlying transform algorithm. If the output of this transform is an OctetStreamData, then this method returns null and the bytes are written to the specified OutputStream. Otherwise, the OutputStream is ignored and the method behaves as if {@link #transform(Data, XMLCryptoContext)} were invoked. param data the data to be transformed param context the XMLCryptoContext containing additional context (may be null if not applicable) param os the OutputStream that should be used to write the transformed data to return the transformed data (or null if the data was written to the OutputStream parameter) throws NullPointerException if data or os is null throws TransformException if an error occurs while executing the transform
