Constructor Detail

DERNumericString

public DERNumericString(byte[] string)

basic constructor - with bytes.

DERNumericString

public DERNumericString(String string)

basic constructor - without validation..

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.

getString

public String getString()

Specified by:

getString in interface DERString

toString

public String toString()

Overrides:

toString in class Object

getOctets

public byte[] getOctets()

hashCode

public int hashCode()

Specified by:

hashCode in class ASN1Object

isNumericString

public static boolean isNumericString(String str)

Return true if the string can be represented as a NumericString ('0'..'9', ' ')

Parameters:

str - string to validate.

Returns:

true if numeric, fale otherwise.
