  org.bouncycastle.asn1.x500.style.AbstractX500NameStyle

All Implemented Interfaces:

X500NameStyle

Direct Known Subclasses:

BCStyle, RFC4519Style

public abstract class AbstractX500NameStyle

extends java.lang.Object

implements X500NameStyle

This class provides some default behavior and common implementation for a X500NameStyle. It should be easily extendable to support implementing the desired X500NameStyle.

Method Summary

boolean	areEqual(X500Name name1, X500Name name2) Two names are equal when they carry the same multiset of RDNs, each RDN compared by rdnAreEqual(RDN, RDN).
int	calculateHashCode(X500Name name) Calculate a hashCode for the passed in name.
static java.util.Hashtable	copyHashTable(java.util.Hashtable paramsMap) Tool function to shallow copy a Hashtable.
protected ASN1Encodable	encodeStringValue(ASN1ObjectIdentifier oid, java.lang.String value) Encoded every value into a UTF8String.
protected boolean	rdnAreEqual(RDN rdn1, RDN rdn2)
ASN1Encodable	stringToValue(ASN1ObjectIdentifier oid, java.lang.String value) For all string values starting with '#' is assumed, that these are already valid ASN.1 objects encoded in hex.

public AbstractX500NameStyle()

Method Detail

copyHashTable

public static java.util.Hashtable copyHashTable(java.util.Hashtable paramsMap)

Tool function to shallow copy a Hashtable.

Parameters:

paramsMap - table to copy

Returns:

the copy of the table

calculateHashCode

public int calculateHashCode(X500Name name)

Description copied from interface: X500NameStyle

Calculate a hashCode for the passed in name.

Specified by:

calculateHashCode in interface X500NameStyle

Parameters:

name - the name the hashCode is required for.

Returns:

the calculated hashCode.

stringToValue

public ASN1Encodable stringToValue(ASN1ObjectIdentifier oid,
                                   java.lang.String value)

For all string values starting with '#' is assumed, that these are already valid ASN.1 objects encoded in hex.

All other string values are send to encodeStringValue(ASN1ObjectIdentifier, String).

Subclasses should overwrite encodeStringValue(ASN1ObjectIdentifier, String) to change the encoding of specific types.

Specified by:

stringToValue in interface X500NameStyle

Parameters:

oid - the DN name of the value.

value - the String representation of the value.

Returns:

the ASN.1 equivalent for the value.

encodeStringValue

protected ASN1Encodable encodeStringValue(ASN1ObjectIdentifier oid,
                                          java.lang.String value)

Encoded every value into a UTF8String.

Subclasses should overwrite this method to change the encoding of specific types.

Parameters:

oid - the DN oid of the value

value - the String representation of the value

Returns:

a the value encoded into a ASN.1 object. Never returns null.

areEqual

public boolean areEqual(X500Name name1,
                        X500Name name2)

Two names are equal when they carry the same multiset of RDNs, each RDN compared by rdnAreEqual(RDN, RDN). The RDNs are first compared position by position, in the order they appear or, when the first attribute types differ, in reverse (the usual two encodings of one name); only when that fails are the two multisets compared, by sorting the canonical form of every RDN once, so a name reached from untrusted data costs n log n in its number of RDNs rather than the n squared of a pairwise search. A subclass that overrides rdnAreEqual is consulted on the positional pass; the multiset pass compares the canonical forms of IETFUtils.canonicalString(ASN1Encodable).

Specified by:

areEqual in interface X500NameStyle

Parameters:

name1 - first name for comparison.

name2 - second name for comparison.

Returns:

true if name1 = name 2, false otherwise.

rdnAreEqual

protected boolean rdnAreEqual(RDN rdn1,
                              RDN rdn2)
