Constructor Detail

DERNumericString

public DERNumericString(byte[] string)
basic constructor - with bytes.


DERNumericString

public DERNumericString(java.lang.String string)
basic constructor - without validation..


DERNumericString

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

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

getInstance

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

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

getInstance

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