Method Detail
-
getContentType
public OBJECT_IDENTIFIER getContentType()
Returns the contentType field, which determines what kind of content is contained in this ContentInfo. It will usually be one of the six predefined types, but may also be a user-defined type.
-
hasContent
public boolean hasContent()
Returnstrue
if the content field is present.
-
getInterpretedContent
public ASN1Value getInterpretedContent() throws InvalidBERException
Returns the content, interpreted based on its type. If there is no content,null
is returned.If the contentType is one of the six standard types, the returned object will be of that type. For example, if the ContentInfo has contentType signedData, a SignedData object will be returned. If the contentType is data, an OCTET_STRING will be returned.
If the contentType is not one of the six standard types, the returned object will be an ANY.
- Throws:
InvalidBERException
-
getContent
public ANY getContent()
Returns the content encoded as an ANY. If there is no content,null
is returned.
-
