DERNumericString

public DERNumericString(String string,
                        boolean validate)
Constructor with optional validation.

Parameters:
string - the base string to wrap.
validate - whether or not to check the string.
Throws:
IllegalArgumentException - if validate is true and the string contains characters that should not be in a NumericString.
Method Detail

getInstance

public static DERNumericString getInstance(Object obj)
return a Numeric string from the passed in object

Throws:
IllegalArgumentException - if the object cannot be converted.

getInstance

public static DERNumericString getInstance(ASN1TaggedObject obj,
                                           boolean explicit)
return an Numeric String from a tagged object.

Parameters:
obj - the tagged object holding the object we want
explicit - true if the object is meant to be explicitly tagged false otherwise.
Throws:
IllegalArgumentException - if the tagged object cannot be converted.
