Class: Ldaptic::Filter::Hash

Inherits:
Abstract show all
Defined in:
lib/ldaptic/filter.rb

Overview

A hash is the most general and most useful type of filter builder.

Ldaptic::Filter(
  :givenName => "David",
  :sn! => "Thomas",
  :postalCode => (70000..80000)
).to_s # => "(&(givenName=David)(&(postalCode>=70000)(postalCode<=80000))(!(sn=Thomas)))"

Including :* => true allows asterisks to pass through unaltered. Otherwise, they are escaped.

Ldaptic::Filter(:givenName => "Dav*", :* => true).to_s # => "(givenName=Dav*)"
