Detailed Description

\inmodule QtLocation

Since: 5.6

The QPlaceSearchRequest class represents the set of parameters for a search request.

A typical search request may look like the following:

Note that specifying a search center can be done by setting a circular search area that has a center but no radius. The default radius is set to -1, which indicates an undefined radius. The provider will interpret this as being free to choose its own default radius.

The QPlaceSearchRequest is primarily used with the QPlaceManager to \l {QPlaceManager::search()} {search for places}, however it is also used to provide parameters for \l {QPlaceManager::searchSuggestions()}{generating search term suggestions}. Note that in this context only some of the parameters may be relevant. For example, the search area is useful in narrowing down relevant search suggestions, while other parameters such as relevance hint are not so applicable.

Also be aware that providers may vary by which parameters they support for example some providers may not support paging while others do, some providers may honor relevance hints while others may completely ignore them, see the \l {Qt Location::Plugin References and Parameters}{plugin documentation} for more details.

Member Enumeration Documentation

◆ RelevanceHint

enum QPlaceSearchRequest::RelevanceHint

Defines hints to help rank place results.

\value UnspecifiedHint No explicit hint has been specified. \value DistanceHint Distance to a search center is relevant for the user. Closer places are more highly weighted. This hint is only useful if a circular search area is used in the query. \value LexicalPlaceNameHint Alphabetic ordering of places according to name is relevant to the user.

◆ QPlaceSearchRequest() [1/3]

QPlaceSearchRequest::QPlaceSearchRequest ( )

Default constructor.

Constructs an new request object.

Definition at line 104 of file qplacesearchrequest.cpp.

◆ QPlaceSearchRequest() [2/3]

QPlaceSearchRequest::QPlaceSearchRequest ( const QPlaceSearchRequest & other )

defaultnoexcept

Constructs a copy of other.

◆ QPlaceSearchRequest() [3/3]

QPlaceSearchRequest::QPlaceSearchRequest ( QPlaceSearchRequest && other )

QPlaceSearchRequest::~QPlaceSearchRequest ( )

default

Destroys the request object.

Member Function Documentation

◆ categories()

QList< QPlaceCategory > QPlaceSearchRequest::categories ( ) const

Return the categories to be used in the search request.

Places need only to belong to one of the categories to be considered a match by the request.

◆ clear()

void QPlaceSearchRequest::clear ( )

Clears the search request.

Definition at line 341 of file qplacesearchrequest.cpp.

References d.

◆ limit()

int QPlaceSearchRequest::limit ( ) const

Returns the maximum number of search results to retrieve.

A negative value for limit means that it is undefined. It is left up to the backend provider to choose an appropriate number of results to return. The default limit is -1.

noexcept

Assigns other to this search request and returns a reference to this search request.

QString QPlaceSearchRequest::recommendationId ( ) const

Returns the place id which will be used to search for recommendations for similar places.

Here is the caller graph for this function:

◆ relevanceHint()

QPlaceSearchRequest::RelevanceHint QPlaceSearchRequest::relevanceHint ( ) const

Returns the relevance hint of the request.

The hint is given to the provider to help but not dictate the ranking of results. For example providing a distance hint may give closer places a higher ranking but it doesn't necessarily mean that he results will be ordered strictly according to distance.

The default search area is an invalid QGeoShape, indicating that no specific search area is defined.

◆ setSearchContext()

void QPlaceSearchRequest::setSearchContext ( const QVariant & context )

Sets the search context to context.

Note: This method is intended to be used by geo service plugins when returning search results of type \l QPlaceSearchResult::ProposedSearchResult.

The search context is used by backends to store additional search context related to the search request. Other relevant fields should also be filled in. For example, if the search context encodes a text search the search term should also be set with \l setSearchTerm(). The search context allows additional search context to be kept which is not directly accessible via the Qt Location API.

The search context can be of any type storable in a QVariant. The value of the search context is not intended to be use directly by applications.
