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:

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

Parameters:

obj - a DERNumericString or an object that can be converted into one.

Returns:

a DERNumericString instance, or null

Throws:

java.lang.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.

Returns:

a DERNumericString instance, or null.

Throws:

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

getString

Description copied from interface: ASN1String

Return a Java String representation of this STRING type's content.

Specified by:

getString in interface ASN1String

Returns:

a Java String representation of this STRING.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getOctets

public byte[] getOctets()

hashCode

public int hashCode()

Specified by:

hashCode in class ASN1Primitive

isNumericString

public static boolean isNumericString(java.lang.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.
