Method Detail

getInstance

public static ContentInfo getInstance(java.lang.Object obj)

Return an ContentInfo object from the given object.

Accepted inputs:

• null → null
• ContentInfo object
• ASN1Sequence input formats with ContentInfo structure inside

Parameters:

obj - the object we want converted.

Throws:

java.lang.IllegalArgumentException - if the object cannot be converted.

getInstance

                                      boolean explicit)

getContentType

public ASN1ObjectIdentifier getContentType()

getContent

public ASN1Encodable getContent()

isDefiniteLength

public boolean isDefiniteLength()

Return true if this object encapsulates a definite-length structure.

Returns:

true if definite-length, false if indefinite.

toASN1Primitive

public ASN1Primitive toASN1Primitive()

Produce an object suitable for an ASN1OutputStream.

Specified by:

toASN1Primitive in interface ASN1Encodable

Specified by:

toASN1Primitive in class ASN1Object

Returns:

a primitive representation of this object.
