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

public java.lang.String getString()
Description copied from interface: ASN1String
Return a Java String representation of this STRING type's content.
Specified by:
getString in interface ASN1String
Following copied from interface: org.bouncycastle.asn1.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()
Overrides:
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.
