Detailed Description

An RFC 1960-based Filter.

A LDAPFilter can be used numerous times to determine if the match argument matches the filter string that was used to create the LDAPFilter.

Some examples of LDAP filters are:

• "(cn=Babs Jensen)"
• "(!(cn=Tim Howes))"
• "(&(" + ServiceConstants::OBJECTCLASS() + "=Person)(|(sn=Jensen)(cn=Babs J*)))"
• "(o=univ*of*mich*)"

Remarks

This class is thread safe.

Constructor & Destructor Documentation

LDAPFilter::LDAPFilter

(

)

Creates in invalid LDAPFilter object.

Test the validity by using the boolean conversion operator.

Calling methods on an invalid LDAPFilter will result in undefined behavior.

LDAPFilter::LDAPFilter

(

const std::string &

filter

)

Creates a LDAPFilter object.

This LDAPFilter object may be used to match a ServiceReference object or a ServiceProperties object.

If the filter cannot be parsed, an std::invalid_argument will be thrown with a human readable message where the filter became unparsable.

Parameters

filter

The filter string.

Returns

A LDAPFilter object encapsulating the filter string.

Exceptions

std::invalid_argument

If filter contains an invalid filter string that cannot be parsed.

Member Function Documentation

bool LDAPFilter::Match

(

const ServiceReference &

reference

)

const

Filter using a service's properties.

This LDAPFilter is executed using the keys and values of the referenced service's properties. The keys are looked up in a case insensitive manner.

Parameters

reference

The reference to the service whose properties are used in the match.

Returns

true if the service's properties match this LDAPFilter false otherwise.

bool LDAPFilter::Match

(

const ServiceProperties &

dictionary

)

const

Filter using a ServiceProperties object with case insensitive key lookup.

This LDAPFilter is executed using the specified ServiceProperties's keys and values. The keys are looked up in a case insensitive manner.

Parameters

dictionary

The ServiceProperties whose key/value pairs are used in the match.

Returns

true if the ServiceProperties's values match this filter; false otherwise.

bool LDAPFilter::MatchCase

(

const ServiceProperties &

dictionary

)

const

Filter using a ServiceProperties.

This LDAPFilter is executed using the specified ServiceProperties's keys and values. The keys are looked up in a normal manner respecting case.

Parameters

dictionary

The ServiceProperties whose key/value pairs are used in the match.

Returns

true if the ServiceProperties's values match this filter; false otherwise.

LDAPFilter::operator bool

(

)

const

LDAPFilter& LDAPFilter::operator=

(

const LDAPFilter &

filter

)

bool LDAPFilter::operator==

(

const LDAPFilter &

other

)

const

Compares this LDAPFilter to another LDAPFilter.

This implementation returns the result of calling this->ToString() == other.ToString().

Parameters

other

The object to compare against this LDAPFilter.

Returns

Returns the result of calling this->ToString() == other.ToString().

std::string LDAPFilter::ToString

(

)

const

Returns this LDAPFilter's filter string.

The filter string is normalized by removing whitespace which does not affect the meaning of the filter.

Returns

This LDAPFilter's filter string.
