build (args)
Source

    # File lib/uri/ldap.rb, line 74
    def self.build(args)
      tmp = Util::make_components_hash(self, args)

      if tmp[:dn]
        tmp[:path] = tmp[:dn]
      end

      query = []
      [:extensions, :filter, :scope, :attributes].collect do |x|
        next if !tmp[x] && query.size == 0
        query.unshift(tmp[x])
      end

      tmp[:query] = query.join('?')

      return super(tmp)
    end

## Description¶ ↑

Creates a new `URI::LDAP` object from components, with syntax checking.

The components accepted are host, port, dn, attributes, scope, filter, and extensions.

The components should be provided either as an `Array`, or as a `Hash` with keys formed by preceding the component names with a colon.

If an `Array` is used, the components must be passed in the order `[host, port, dn, attributes, scope, filter, extensions]`.

Example:

    uri = URI::LDAP.build({:host => 'ldap.example.com',
      :dn => '/dc=example'})

    uri = URI::LDAP.build(["ldap.example.com", nil,
      "/dc=example;dc=com", "query", nil, nil, nil])

Calls superclass method `URI::Generic::build`
new (*arg)
Source

    # File lib/uri/ldap.rb, line 108
    def initialize(*arg)
      super(*arg)

      if @fragment
        raise InvalidURIError, 'bad LDAP URL'
      end

      parse_query
    end

## Description¶ ↑

Creates a new `URI::LDAP` object from generic `URI` components as per RFC 2396. No LDAP-specific syntax checking is performed.

Arguments are `scheme`, `userinfo`, `host`, `port`, `registry`, `path`, `opaque`, `query`, and `fragment`, in that order.

Example:

    uri = URI::LDAP.new("ldap", nil, "ldap.example.com", nil, nil,
      "/dc=example;dc=com", nil, "query", nil)

See also `URI::Generic.new`.

Calls superclass method `URI::Generic::new`
