Detailed Description

This class represents one search pattern rule.

Incoming mail is sent through the list of mail filter rules before it is placed in the associated mail folder (usually "inbox"). This class represents one mail filter rule. It is also used to represent a search rule as used by the search dialog and folders.

Member Typedef Documentation

Ptr

using MailCommon::SearchRule::Ptr = std::shared_ptr<SearchRule>

Defines a pointer to a search rule.

Definition at line 29 of file searchrule.h.

Member Enumeration Documentation

Function

enum MailCommon::SearchRule::Function

Describes operators for comparison of field and contents.

If you change the order or contents of the enum: do not forget to change funcConfigNames[], sFilterFuncList and matches() in SearchRule, too. Also, it is assumed that these functions come in pairs of logical opposites (ie. "=" <-> "!=", ">" <-> "<=", etc.).

Definition at line 40 of file searchrule.h.

RequiredPart

enum MailCommon::SearchRule::RequiredPart

Possible required parts.

Enumerator
Envelope	Envelope.
Header	Header.
CompleteMessage	Whole message.

Definition at line 70 of file searchrule.h.

Member Function Documentation

addQueryTerms()

virtual void MailCommon::SearchRule::addQueryTerms ( Akonadi::SearchTerm & groupTerm, bool & emptyIsNotAnError ) const

inlinevirtual

Adds query terms to the given term group.

Reimplemented in MailCommon::SearchRuleNumerical, and MailCommon::SearchRuleStatus.

Definition at line 233 of file searchrule.h.

akonadiComparator()

Akonadi::SearchTerm::Condition SearchRule::akonadiComparator ( ) const

nodiscardprotected

Converts the rule function into the corresponding Akonadi query operator.

Definition at line 530 of file searchrule.cpp.

asString()

const QString SearchRule::asString ( ) const

nodiscard

Returns the rule as string for debugging purpose.

Definition at line 521 of file searchrule.cpp.

contents()

QString SearchRule::contents ( ) const

nodiscard

Returns the contents of the rule.

Definition at line 516 of file searchrule.cpp.

createInstance() [1/4]

SearchRule::Ptr SearchRule::createInstance ( const QByteArray & field, const char * function, const QString & contents )

static

Creates a new search rule of a certain type by instantiating the appropriate subclass depending on the field.

Parameters

field	The field to search in.
function	The name of the function to use for searching.
contents	The contents to search for.

Definition at line 101 of file searchrule.cpp.

createInstance() [2/4]

SearchRule::Ptr SearchRule::createInstance ( const QByteArray & field = QByteArray(), Function function = FuncContains, const QString & contents = QString() )

static

Creates a new search rule of a certain type by instantiating the appropriate subclass depending on the field.

Parameters

field	The field to search in.
function	The function to use for searching.
contents	The contents to search for.

Definition at line 79 of file searchrule.cpp.

createInstance() [3/4]

SearchRule::Ptr SearchRule::createInstance ( const SearchRule & other )

static

Creates a new search rule by cloning an other rule.

Definition at line 106 of file searchrule.cpp.

createInstance() [4/4]

SearchRule::Ptr SearchRule::createInstance ( QDataStream & stream )

static

Creates a new search rule by deseralizing its structure from a data stream.

Definition at line 130 of file searchrule.cpp.

createInstanceFromConfig()

SearchRule::Ptr SearchRule::createInstanceFromConfig ( const KConfigGroup & group, int index )

static

Creates a new search rule from a given config group.

Parameters

group	The config group to read the structure from.
index	The identifier that is used to distinguish rules within a single config group.

Note

This function does no validation of the data obtained from the config file. You should call isEmpty yourself if you need valid rules.

Definition at line 111 of file searchrule.cpp.

field()

QByteArray SearchRule::field ( ) const

nodiscard

Returns the message header field name (without the trailing ':').

There are also six pseudo-headers:

• <message>: Try to match against the whole message.
• <body>: Try to match against the body of the message.
• <any header>: Try to match against any header field.
• <recipients>: Try to match against both To: and Cc: header fields.
• <size>: Try to match against size of message (numerical).
• <age in days>: Try to match against age of message (numerical).
• <status>: Try to match against status of message (status).
• <tag>: Try to match against message tags.

Definition at line 506 of file searchrule.cpp.

function()

SearchRule::Function SearchRule::function

(

)

const

Returns the filter function of the rule.

Definition at line 496 of file searchrule.cpp.

generateSieveScript()

void SearchRule::generateSieveScript	(	QStringList &	requireModules,
		QString &	code )

Definition at line 251 of file searchrule.cpp.

informationAboutNotValidRules()

virtual QString MailCommon::SearchRule::informationAboutNotValidRules ( ) const

inlinevirtual

Definition at line 240 of file searchrule.h.

isEmpty()

virtual bool MailCommon::SearchRule::isEmpty ( ) const

pure virtual

Determines whether the rule is worth considering.

It isn't if either the field is not set or the contents is empty. The calling code should make sure that it's rule list contains only non-empty rules, as matches doesn't check this.

Implemented in MailCommon::SearchRuleNumerical, and MailCommon::SearchRuleStatus.

isNegated()

bool SearchRule::isNegated ( ) const

nodiscardprotected

Helper that returns whether the rule has a negated function.

Definition at line 571 of file searchrule.cpp.

matches()

virtual bool MailCommon::SearchRule::matches ( const Akonadi::Item & item ) const

pure virtual

Tries to match the rule against the KMime::Message in the given item.

Returns

true if the rule matched, false otherwise.

Note

Must be implemented by subclasses.

Implemented in MailCommon::SearchRuleNumerical, and MailCommon::SearchRuleStatus.

operator=()

const SearchRule & SearchRule::operator=

(

const SearchRule &

other

)

Initializes this rule with an other rule.

Definition at line 66 of file searchrule.cpp.

operator>>()

QDataStream & SearchRule::operator>>

(

QDataStream &

s

)

const

Definition at line 590 of file searchrule.cpp.

requiredPart()

virtual SearchRule::RequiredPart MailCommon::SearchRule::requiredPart ( ) const

pure virtual

Returns the required part from the item that is needed for the search to operate.

See RequiredPart

Implemented in MailCommon::SearchRuleNumerical, and MailCommon::SearchRuleStatus.

setContents()

void SearchRule::setContents

(

const QString &

contents

)

Set the contents of the rule.

This can be either a substring to search for in or a regexp pattern to match against the header.

Definition at line 511 of file searchrule.cpp.

setField()

void SearchRule::setField

(

const QByteArray &

name

)

Sets the message header field name.

Note

Make sure the name contains no trailing ':'.

Definition at line 501 of file searchrule.cpp.

setFunction()

void SearchRule::setFunction

(

Function

function

)

Sets the filter function of the rule.

Definition at line 491 of file searchrule.cpp.

writeConfig()

void SearchRule::writeConfig	(	KConfigGroup &	group,
		int	index ) const

Saves the object into a given config group.

Parameters

group	The config group.
index	The identifier that is used to distinguish rules within a single config group.

Note

This function will happily write itself even when it's not valid, assuming higher layers to Do The Right Thing(TM).
