# Result Class Reference

`from PyKDE4.nepomuk import *`

Namespace: Nepomuk.Query

## Detailed Description

\class Result result.h Nepomuk/Query/Result

A single search result.

A search via QueryServiceClient returns a set of Result object. A result consists of a Nepomuk.Resource and an optional score.

Additional bindings (variable values) as requested via ComparisonTerm.setVariableName() can be retrieved using additionalBinding().

## Method Documentation

__init__ | ( |  | self ) |

Copy constructor.

__init__ | ( | self, |
|  | Nepomuk.Resource | resource,
|  | float | score=0.0
| ) |  |  |

Create a new result.

Parameters:

  | resource | The result resource.

Parameters:

  | score | The optional result score.

__init__ | ( | self, |
|  | Nepomuk.Query.Result | a0
| ) |  |  |

Copy constructor.

addRequestProperty | ( | self, |
|  | Nepomuk.Types.Property | property,
|  | Soprano.Node | value
| ) |  |  |

Add the value of a request property.

\sa Query.RequestProperty

Nepomuk.Variant additionalBinding | ( | self, |
|  | QString | name
| ) |  |  |

Retrieve an additional binding as returned by the query. Typically these bindings are created via ComparisonTerm.setVariableName(). But they could also stem from custom SPARQL queries. A simple example would be:

     select ?r ?rating where { ?r nao:numericRating ?rating . }

Here ?r would be used as the result's resource while ?rating could be accessed via

     additionalBinding( QLatin1String("rating") );

If for some reason one needs the plain binding values one could use additionalBinding().

Soprano.BindingSet additionalBindings | ( |  | self ) |

Retrieve the set of additional bindings as set via setAdditionalBindings(). Normally one would use additionalBinding() instead.

Since:
  4.5

bool operator == | ( | self, |
|  | Nepomuk.Query.Result | a0
| ) |  |  |

Comparison operator

Soprano.Node operator [] | ( | self, |
|  | Nepomuk.Types.Property | property
| ) |  |  |

Retrieve value of request property property.

\sa requestProperties, addRequestProperty

{Nepomuk.Types.Property:Soprano.Node} requestProperties | ( |  | self ) |

Retrieve the values of the request properties.

\sa Query.RequestProperty

Soprano.Node requestProperty | ( | self, |
|  | Nepomuk.Types.Property | property
| ) |  |  |

Retrieve value of request property property.

\sa additionalBinding, requestProperties, addRequestProperty

Nepomuk.Resource resource | ( |  | self ) |

The result resource.

float score | ( |  | self ) |

The score of the result. By default the value is 0.0 which means no score.

\sa setScore

setAdditionalBindings | ( | self, |
|  | Soprano.BindingSet | bindings
| ) |  |  |

Set the additional bindings a query returned besides the result itself and the request properties.

Normally there is no need to call this method as the query service does set the bindings.

Since:
  4.5

setScore | ( | self, |
|  | float | score
| ) |  |  |

Set the score of the result.

\sa score
