Class CMSCompressedDataInputConnector

java.lang.Object
oracle.security.crypto.cms.CMSCompressedDataInputConnector

All Implemented Interfaces:

CMSInputConnector

public class CMSCompressedDataInputConnector

extends java.lang.Object

implements CMSInputConnector

A CMSCompressedDataInputConnector is used in place of a CMSCompressedDataInputStream when reading nested CMS objects containing compressed-data structures.

A CMSCompressedDataInputConnector is essentially a input stream filter that unwraps the CMS compressed-data structure from the data read in. A CMSCompressedDataInputConnector expects the Content field of the CMS ContentInfo structure i.e. the underlying input stream must be positioned just after the explicit [0] tag wrapper.

CMSInputConnector, CMSCompressedDataInputStream
