Class CMSCompressedDataOutputConnector

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

All Implemented Interfaces:

CMSOutputConnector

public class CMSCompressedDataOutputConnector

extends java.lang.Object

implements CMSOutputConnector

A CMSCompressedDataOutputConnector is used in place of a CMSCompressedDataOutputStream when constructing nested CMS objects containing compressed-data structures.

A CMSCompressedDataOutputConnector is essentially an output stream filter that wraps the data written to it within a CMS compressed-data structure. Only the Content field of the CMS ContentInfo structure minus the the explicit [0] tag wrapper is written to the underlying output stream.

See Also:

CMSOutputConnector, CMSCompressedDataOutputStream

Constructor Summary

CMSCompressedDataOutputConnector(CMSOutputConnector conn, oracle.security.crypto.core.AlgorithmIdentifier compressionAlgID, oracle.security.crypto.asn1.ASN1ObjectID contentType)
Creates a CMSCompressedDataOutputConnector.

CMSCompressedDataOutputConnector(java.io.OutputStream out, oracle.security.crypto.core.AlgorithmIdentifier compressionAlgID, oracle.security.crypto.asn1.ASN1ObjectID contentType)
Creates a CMSCompressedDataOutputConnector.

Method Summary

oracle.security.crypto.asn1.ASN1ObjectID	getExposedContentType() Returns the content type of the data that is output to the underlying output stream.
java.io.OutputStream	getOutputStream() Returns the output stream that is governed by this connector.

CMSCompressedDataOutputConnector

public CMSCompressedDataOutputConnector(java.io.OutputStream out,
                                        oracle.security.crypto.core.AlgorithmIdentifier compressionAlgID,
                                        oracle.security.crypto.asn1.ASN1ObjectID contentType)
                                 throws oracle.security.crypto.core.AlgorithmIdentifierException

Creates a CMSCompressedDataOutputConnector.

Parameters:

out - The underlying output stream.

compressionAlgID - The compression algorithm identifier.

contentType - The content type of the enclosing content.

Throws:

oracle.security.crypto.core.AlgorithmIdentifierException - Compression algorithm is not supported.

CMSCompressedDataOutputConnector

public CMSCompressedDataOutputConnector(CMSOutputConnector conn,
                                        oracle.security.crypto.core.AlgorithmIdentifier compressionAlgID,
                                        oracle.security.crypto.asn1.ASN1ObjectID contentType)
                                 throws oracle.security.crypto.core.AlgorithmIdentifierException

Creates a CMSCompressedDataOutputConnector.

Parameters:

conn - The underlying output connector.

compressionAlgID - The compression algorithm identifier.

contentType - The content type of the enclosing content.

writeEContentInfo - true if the enclosed content must be written to the output stream; false otherwise.

Throws:

oracle.security.crypto.core.AlgorithmIdentifierException - Compression algorithm is not supported.
