Net::LDAP::Filter - representation of LDAP filters

Create a new object and parse FILTER.
- parse ( FILTER )
Parse FILTER. The next call to ber will return this filter encoded.
Return the filter in text form.
- print ( [ FH ] )
Print the text representation of the filter to FH, or the currently selected output handle if FH is not given.
