Detailed Description
This class is a basic messaging class used to exchange filtering information between the filter plugins and the application requesting the filtering service.
Use this object if you require a more detailed information about the URI you want to filter. Any application can create an instance of this class and send it to KUriFilter to have the plugins fill out all possible information about the URI.
On successful filtering you can use uriType() to determine what type of resource the request was filtered into. See KUriFilter::UriTypes for details. If an error is encountered, then KUriFilter::Error is returned. You can use errorMsg to obtain the error information.
The functions in this class are not reentrant.
Example
Here is a basic example of how this class is used with KUriFilter:
KUriFilterData filterData (QLatin1String("kde.org")); bool filtered = KUriFilter::self()->filterUri(filterData);
If you are only interested in getting the list of preferred search providers, then you can do the following (requires KDE >= 4.5):
KDE 4.5: KUriFilterData data; data.setData("<text-to-search-for>"); data.setAlternateDefaultSearchProvider("google"); bool filtered = KUriFilter::self()->filterUri(data, "kuriikwsfilter"); KDE >= 4.6: KUriFilterData data; data.setData("<text-to-search-for>"); data.setSearchFilteringOption(KUriFilterData::RetrievePreferredSearchProvidersOnly); bool filtered = KUriFilter::self()->filterSearchUri(data, KUriFilter::NormalTextFilter);
A class for exchanging filtering information.

Member Enumeration Documentation
This enum describes the search filtering options to be used.
- SearchFilterOptionNone No search filter options are set and normal filtering is performed on the input data.
- RetrieveSearchProvidersOnly If set, the list of all available search providers are returned without any input filtering. This flag only applies when used in conjunction with the KUriFilter::NormalTextFilter flag.
- RetrievePreferredSearchProvidersOnly If set, the list of preferred search providers are returned without any input filtering. This flag only applies when used in conjunction with the KUriFilter::NormalTextFilter flag.
- RetrieveAvailableSearchProvidersOnly Same as doing RetrievePreferredSearchProvidersOnly | RetrieveSearchProvidersOnly, where all available search providers are returned if no preferred ones ones are available. No input filtering will be performed.
- Since:
- 4.6
- Enumerator:
SearchFilterOptionNone RetrieveSearchProvidersOnly RetrievePreferredSearchProvidersOnly RetrieveAvailableSearchProvidersOnly

| QStringList KUriFilterData::preferredSearchProviders | ( | ) | const |
Returns a list of the names of preferred or available search providers.
This function returns the list of providers marked as preferred whenever the input data, i.e. typedString, is successfully filtered.

To avoid this problem you must either set an alternate default search provider using setAlternateDefaultSearchProvider or set one of the SearchFilterOption flags if you are only interested in getting the list of providers and not filtering the input.
Additionally, you can also provide alternate search providers in case there are no preferred ones already selected.
You can use queryForPreferredServiceProvider to obtain the query associated with the list of search providers returned by this function.

Sets the absolute path to be used whenever the supplied data is a relative local URL.
NOTE: This function should only be used for local resources, i.e. the "file:/" protocol. It is useful for specifying the absolute path in cases where the actual URL might be relative. If deriving the path from a KUrl, make sure you set the argument for this function to the result of calling path () instead of url ().
- Parameters:
-
abs_path the abolute path to the local resource.
- Returns:
- true if absolute path is successfully set. Otherwise, false.
Definition at line 437 of file kurifilter.cpp.
| void KUriFilterData::setAlternateDefaultSearchProvider | ( | const QString & | provider | ) |
Sets the search provider to use in case no default provider is available.
The default search provider set using this function will only be used if the default and favorite search providers have not yet been selected by the user. Otherwise, the default provider specified by through function will be ignored.
- Since:
- 4.5
Definition at line 459 of file kurifilter.cpp.
| void KUriFilterData::setAlternateSearchProviders | ( | const QStringList & | providers | ) |
Sets a list of search providers to use in case no preferred search providers are available.
The list of preferred search providers set using this function will only be used if the default and favorite search providers have not yet been selected by the user. Otherwise, the providers specified through this function will be ignored.
- Since:
- 4.5
Definition at line 454 of file kurifilter.cpp.
| void KUriFilterData::setCheckForExecutables | ( | bool | check | ) |
Check whether the provided uri is executable or not.
Setting this to false ensures that typing the name of an executable does not start that application. This is useful in the location bar of a browser. The default value is true.
Definition at line 449 of file kurifilter.cpp.
| void KUriFilterData::setData | ( | const KUrl & | url | ) |
Same as above except the argument is a URL.
Use this function to set the string to be filtered when you construct an empty filter object.
- Parameters:
-
url the URL to be filtered.
Definition at line 427 of file kurifilter.cpp.
| void KUriFilterData::setData | ( | const QString & | url | ) |
Sets the URL to be filtered.
Use this function to set the string to be filtered when you construct an empty filter object.
- Parameters:
-
url the string to be filtered.
Definition at line 432 of file kurifilter.cpp.
| void KUriFilterData::setDefaultUrlScheme | ( | const QString & | scheme | ) |
Sets the default scheme used when filtering potentially valid url inputs.
Use this function to change the default protocol used when filtering potentially valid url inputs. The default protocol is http.
If the scheme is specified without a separator, then "://" will be used as the separator by default. For example, if the default url scheme was simply set to "ftp", then a potentially valid url input such as "kde.org" will be filtered to "ftp://kde.org".
- See also:
- defaultUrlScheme
- Since:
- 4.6
Definition at line 464 of file kurifilter.cpp.
| void KUriFilterData::setSearchFilteringOptions | ( | SearchFilterOptions | options | ) |
Sets the options used by search filter plugins to filter requests.
The default search filter option is SearchFilterOptionNone. See SearchFilterOption for the description of the other flags.
It is important to note that the options set through this function can prevent any filtering from being performed by search filter plugins. As such, uriTypes can return KUriFilterData::Unknown and uri can return an invalid url eventhough the filtering request returned a successful response.
- See also:
- searchFilteringOptions
- Since:
- 4.6
Definition at line 469 of file kurifilter.cpp.
| QString KUriFilterData::typedString | ( | ) | const |

Definition at line 338 of file kurifilter.cpp.
| KUrl KUriFilterData::uri | ( | ) | const |

- Returns:
- the filtered or original url.
Definition at line 298 of file kurifilter.cpp.
| KUriFilterData::UriTypes KUriFilterData::uriType | ( | ) | const |
Returns the URI type.
This method always returns KUriFilterData::UNKNOWN if the given URL was not filtered.
- Returns:
- the type of the URI
