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.
