Filter class

An LDAP search filter.

An LDAP search filter can be a single filter created using either of these factory methods:

  • present - matches if the entry contains the attribute
  • equals - matches if an attribute has a given value
  • substring - matches wildcard
  • approx - matches if an attribute approximately has the value
  • greaterOrEquals - matches if the value is greater than or equal
  • lessOrEquals - matches if the entry has the attribute with a value that is less than or equal to the supplied value

Or it can be a compound filter that composes other filters created using these factory methods:

  • not - matches if its member filter does not match
  • and - matches if all of its member filters match
  • or - matches if at least one of its member filters match
