Class ASN1NumericString

java.lang.Object

org.bouncycastle.asn1.ASN1Object

org.bouncycastle.asn1.ASN1Primitive

org.bouncycastle.asn1.ASN1NumericString

All Implemented Interfaces:

ASN1Encodable, ASN1String, Encodable

Direct Known Subclasses:

DERNumericString

public abstract class ASN1NumericString
extends ASN1Primitive
implements ASN1String

NumericString object - this is an ascii string of characters {0,1,2,3,4,5,6,7,8,9, }. ASN.1 NUMERIC-STRING object.

This is an ASCII string of characters {0,1,2,3,4,5,6,7,8,9} + space.

See X.680 section 37.2.

Explicit character set escape sequences are not allowed.

Method Detail

getInstance

public static ASN1NumericString getInstance(java.lang.Object obj)

Return a Numeric string from the passed in object

Parameters:

obj - an ASN1NumericString or an object that can be converted into one.

Returns:

an ASN1NumericString instance, or null

Throws:

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

getInstance

public static ASN1NumericString getInstance(ASN1TaggedObject taggedObject,
                                            boolean explicit)

Return an Numeric String from a tagged object.

Parameters:

taggedObject - the tagged object holding the object we want

explicit - true if the object is meant to be explicitly tagged false otherwise.

Returns:

an ASN1NumericString instance, or null.

Throws:

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

getString

public final 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

Returns:

a Java String representation of this STRING.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getOctets

public final byte[] getOctets()

hashCode

public final 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, false otherwise.
