LDAPFilter

std::ostream &cppmicroservices::operator<<(std::ostream &os, const LDAPFilter &filter)

Streams the string representation of filter into the stream os via LDAPFilter::ToString().

cppmicroservices::LDAPPropExpr operator&&(const cppmicroservices::LDAPPropExpr &left, const cppmicroservices::LDAPPropExpr &right)

LDAP logical and ‘&’.

Return

A LDAP expression

Parameters

• left: A LDAP expression.
• right: A LDAP expression.

cppmicroservices::LDAPPropExpr operator||(const cppmicroservices::LDAPPropExpr &left, const cppmicroservices::LDAPPropExpr &right)

LDAP logical or ‘|’.

Return

A LDAP expression

Parameters

• left: A LDAP expression.
• right: A LDAP expression.

class cppmicroservices::LDAPFilter

#include <cppmicroservices/LDAPFilter.h>

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))”
• “(&(” + Constants::OBJECTCLASS + “=Person)(|(sn=Jensen)(cn=Babs J*)))”
• “(o=univ*of*mich*)”

Remark

This class is thread safe.

See

LDAPProp for a fluent API generating LDAP filter strings

Public Functions

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(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.

Return

A LDAPFilter object encapsulating the filter string.

See

“Framework specification for a description of the filter string syntax.” TODO!

Parameters

• filter: The filter string.

Exceptions

• std::invalid_argument: If filter contains an invalid filter string that cannot be parsed.

LDAPFilter(const LDAPFilter &other)

~LDAPFilter()

operator bool() const

bool Match(const ServiceReferenceBase &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.

Return

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

Parameters

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

bool Match(const Bundle &bundle) const

Filter using a bundle’s manifest properties.

This LDAPFilter is executed using the keys and values of the bundle’s manifest properties. The keys are looked up in a case insensitive manner.

Return

true if the bundle’s properties match this LDAPFilter false otherwise.

Parameters

• bundle: The bundle whose properties are used in the match.

bool Match(const AnyMap &dictionary) const

Filter using a AnyMap object with case insensitive key lookup.

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

Return

true if the AnyMap‘s values match this filter; false otherwise.

Parameters

• dictionary: The AnyMap whose key/value pairs are used in the match.

bool MatchCase(const AnyMap &dictionary) const

Filter using a AnyMap.

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

Return

true if the AnyMap‘s values match this filter; false otherwise.

Parameters

• dictionary: The AnyMap whose key/value pairs are used in the match.

std::string 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.

Return

This LDAPFilter‘s filter string.

bool operator==(const LDAPFilter &other) const

Compares this LDAPFilter to another LDAPFilter.

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

Return

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

Parameters

• other: The object to compare against this LDAPFilter.

LDAPFilter &operator=(const LDAPFilter &filter)

Protected Attributes

SharedDataPointer<LDAPFilterData> d

class cppmicroservices::LDAPProp

#include <cppmicroservices/LDAPProp.h>

A fluent API for creating LDAP filter strings.

Examples for creating LDAPFilter objects:

// This creates the filter "(&(name=Ben)(!(count=1)))"
LDAPFilter filter(LDAPProp("name") == "Ben" && !(LDAPProp("count") == 1));

// This creates the filter "(|(presence=*)(!(absence=*)))"
LDAPFilter filter(LDAPProp("presence") || !LDAPProp("absence"));

// This creates the filter "(&(ge>=-3)(approx~=hi))"
LDAPFilter filter(LDAPProp("ge") >= -3 && LDAPProp("approx").Approx("hi"));
