 org.bouncycastle.asn1.ASN1Encodable content)

Method Details

getInstance

public static ContentInfo getInstance(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:

IllegalArgumentException - if the object cannot be converted.

getInstance

public static ContentInfo getInstance(org.bouncycastle.asn1.ASN1TaggedObject obj,
 boolean explicit)

getContentType

public org.bouncycastle.asn1.ASN1ObjectIdentifier getContentType()

getContent

public org.bouncycastle.asn1.ASN1Encodable getContent()

isDefiniteLength

public boolean isDefiniteLength()

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

Returns:

true if definite-length, false if indefinite.
