Constructor Detail

### CompressedData

    public CompressedData(AlgorithmIdentifier compressionAlgorithm,
                          ContentInfo encapContentInfo)

### CompressedData

    public CompressedData(ASN1Sequence seq)

Method Detail

### getInstance

    public static CompressedData getInstance(ASN1TaggedObject _ato,
                                             boolean _explicit)

  return a CompressedData object from a tagged object.

  Parameters:
    `_ato` - the tagged object holding the object we want.
    `_explicit` - 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.

  Parameters:
    `_obj` - the object we want converted.
  Throws:
    `java.lang.IllegalArgumentException` - if the object cannot be converted.

### getVersion

    public DERInteger getVersion()

### getCompressionAlgorithmIdentifier

    public AlgorithmIdentifier getCompressionAlgorithmIdentifier()

### getEncapContentInfo

    public ContentInfo getEncapContentInfo()

### toASN1Object

    public DERObject toASN1Object()

  Specified by:
    `toASN1Object` in class `ASN1Encodable`
