Class LdapURL

java.lang.Object
  org.apache.directory.shared.ldap.util.LdapURL

public class LdapURL
extends java.lang.Object

Decodes a LdapUrl, and checks that it complies with the RFC 2255. The grammar is the following : ldapurl = scheme "://" [hostport] ["/" [dn ["?" [attributes] ["?" [scope] ["?" [filter] ["?" extensions]]]]]] scheme = "ldap" attributes = attrdesc *("," attrdesc) scope = "base" / "one" / "sub" dn = LdapDN hostport = hostport from Section 5 of RFC 1738 attrdesc = AttributeDescription from Section 4.1.5 of RFC 2251 filter = filter from Section 4 of RFC 2254 extensions = extension *("," extension) extension = ["!"] extype ["=" exvalue] extype = token / xtoken exvalue = LDAPString token = oid from section 4.1 of RFC 2252 xtoken = ("X-" / "x-") token
