Method Detail

getInstance

public static CompressedData getInstance(ASN1TaggedObject ato,
                                         boolean isExplicit)

Return a CompressedData object from a tagged object.

Parameters:

ato - the tagged object holding the object we want.

isExplicit - true if the object is meant to be explicitly tagged false otherwise.

Throws:

java.lang.IllegalArgumentException - if the object held by the tagged object cannot be converted.

getInstance

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

Return a CompressedData object from the given object.

Accepted inputs:

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

Parameters:

obj - the object we want converted.

Throws:

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

getVersion

public ASN1Integer getVersion()

getCompressionAlgorithmIdentifier

public AlgorithmIdentifier getCompressionAlgorithmIdentifier()

getEncapContentInfo

Description copied from class: ASN1Object

Method providing a primitive representation of this object suitable for encoding.

Specified by:

toASN1Primitive in interface ASN1Encodable

Specified by:

toASN1Primitive in class ASN1Object
