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.
