Member Function Documentation

bool Plasma::RunnerContext::addMatch	(	const QString &	term,
		const QueryMatch &	match
	)

Appends a match to the existing list of matches.

If you are going to be adding multiple matches, use addMatches instead.

Parameters

term	the search term that this match was generated for.
match	the match to add

Returns

true if the match was added, false otherwise.

Definition at line 403 of file runnercontext.cpp.

bool Plasma::RunnerContext::addMatches	(	const QString &	term,
		const QList< QueryMatch > &	matches
	)

Appends lists of matches to the list of matches.

This method is thread safe and causes the matchesChanged() signal to be emitted.

Returns

true if matches were added, false if matches were e.g. outdated

Definition at line 368 of file runnercontext.cpp.

bool Plasma::RunnerContext::isValid

(

)

const

Returns

true if this context is no longer valid and therefore matching using it should abort. Most useful as an optimization technique inside of AbstractRunner subclasses in the match method, e.g.:

while (.. a possibly large iteration) { if (!context.isValid()) { return; }

... some processing ... }

While not required to be used within runners, it provies a nice way to avoid unnecessary processing in runners that may run for an extended period (as measured in 10s of ms) and therefore improve the user experience.

4.2.3

Definition at line 362 of file runnercontext.cpp.

QueryMatch Plasma::RunnerContext::match

(

const QString &

id

)

const

Retrieves a match by id.

Parameters

id	the id of the match to return

Returns

the match associated with this id, or an invalid QueryMatch object if the id does not eixst

Definition at line 525 of file runnercontext.cpp.

QList< QueryMatch > Plasma::RunnerContext::matches

(

)

const

Retrieves all available matches for the current search term.

Returns

a list of matches

Definition at line 517 of file runnercontext.cpp.

void Plasma::RunnerContext::matchesChanged ( )

signal

QString Plasma::RunnerContext::mimeType

(

)

const

The mimetype that the search term refers to, if discoverable.

Returns

QString() if the mimetype can not be determined, otherwise the mimetype of the object being referred to by the search string.

Definition at line 357 of file runnercontext.cpp.

RunnerContext & Plasma::RunnerContext::operator=

(

const RunnerContext &

other

)

Assignment operator.

Since

4.4

Definition at line 285 of file runnercontext.cpp.

QString Plasma::RunnerContext::query

(

)

const

Returns

the current search query term.

Definition at line 344 of file runnercontext.cpp.

bool Plasma::RunnerContext::removeMatch

(

const QString

matchId

)

Removes a match from the existing list of matches.

If you are going to be removing multiple matches, use removeMatches instead.

Parameters

matchId

the id of match to remove

Returns

true if the match was removed, false otherwise.

Since

4.4

Definition at line 466 of file runnercontext.cpp.

bool Plasma::RunnerContext::removeMatches

(

const QStringList

matchIdList

)

Removes lists of matches from the existing list of matches.

This method is thread safe and causes the matchesChanged() signal to be emitted.

Parameters

matchIdList

the list of matches id to remove

Returns

true if at least one match was removed, false otherwise.

Since

4.4

Definition at line 429 of file runnercontext.cpp.

bool Plasma::RunnerContext::removeMatches

(

Plasma::AbstractRunner *

runner

)

Removes lists of matches from a given AbstractRunner.

This method is thread safe and causes the matchesChanged() signal to be emitted.

Parameters

runner

the AbstractRunner from which to remove matches

Returns

true if at least one match was removed, false otherwise.

Since

4.10

Definition at line 486 of file runnercontext.cpp.

void Plasma::RunnerContext::reset

(

)

Resets the search term for this object.

This removes all current matches in the process and turns off single runner query mode.

Definition at line 300 of file runnercontext.cpp.

void Plasma::RunnerContext::restore

(

const KConfigGroup &

config

)

Sets the launch counts for the associated match ids.

If a runner adds a match to this context, the context will check if the match id has been launched before and increase the matches relevance correspondingly. In this manner, any front end can implement adaptive search by sorting items according to relevance.

Parameters

config

the config group where launch data was stored

Definition at line 548 of file runnercontext.cpp.

void Plasma::RunnerContext::run

(

const QueryMatch &

match

)

Run a match using the information from this context.

The context will also keep track of the number of times the match was launched to sort future matches according to user habits

Parameters

match

the match to run

Definition at line 575 of file runnercontext.cpp.

void Plasma::RunnerContext::save

(

KConfigGroup &

config

)

Parameters

config

the config group where launch data should be stored

Definition at line 561 of file runnercontext.cpp.

void Plasma::RunnerContext::setQuery

(

const QString &

term

)

Sets the query term for this object and attempts to determine the type of the search.

Definition at line 332 of file runnercontext.cpp.

void Plasma::RunnerContext::setSingleRunnerQueryMode

(

bool

enabled

)

Sets single runner query mode.

Note that a call to reset() will turn off single runner query mode.

4.4

Definition at line 538 of file runnercontext.cpp.

bool Plasma::RunnerContext::singleRunnerQueryMode

(

)

const

Returns

true if the current query is a single runner query

Since

4.4

Definition at line 543 of file runnercontext.cpp.

RunnerContext::Type Plasma::RunnerContext::type

(

)

const

The type of item the search term might refer to.
