Constructor Detail

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:

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:
