## Method Documentation

__init__ | ( |  | self ) |

Create an emtpy set.

__init__ | ( | self, |
|  | Soprano.BindingSet | other
| ) |  |  |

Copy constructor.

QStringList bindingNames | ( |  | self ) |

Returns:
  The names of the bound variables in this set.

bool contains | ( | self, |
|  | QString | name
| ) |  |  |

Check if a certain variable has a binding in this set.

Parameters:

  | name | The variable name.

Returns:
  true if this set contains a binding for the variable name, false otherwise.

int count | ( |  | self ) |

The number of bindings in this set.

Returns:
  The number of bindings.

insert | ( | self, |
|  | QString | name,
|  | Soprano.Node | value
| ) |  |  |

Insert a new binding into the set.

bool operator != | ( | self, |
|  | Soprano.BindingSet | other
| ) |  |  |

Comparison operator.

Since:
  2.5

bool operator == | ( | self, |
|  | Soprano.BindingSet | other
| ) |  |  |

Comparison operator.

Since:
  2.5

Soprano.Node operator [] | ( | self, |
|  | int | offset
| ) |  |  |

Get the binding for a variable.

This is equivalent to value(const QString&) const.

Soprano.Node operator [] | ( | self, |
|  | QString | name
| ) |  |  |

Get the binding for a variable.

This is equivalent to value(const QString&) const.

replace | ( | self, |
|  | int | offset,
|  | Soprano.Node | value
| ) |  |  |

Replaces a value in the binding set.

Since:
  2.3

replace | ( | self, |
|  | QString | name,
|  | Soprano.Node | value
| ) |  |  |

Replaces a value in the binding set.

Since:
  2.3

Soprano.Node value | ( | self, |
|  | int | offset
| ) |  |  |

Get the binding for a variable.

Parameters:

  | name | The name of the requested variable.

Returns:
  The binding for the requested variable or and invalid node if the bindings do not contain the variable.

\sa QueryResultIterator.binding(const QString&) const.

Soprano.Node value | ( | self, |
|  | QString | name
| ) |  |  |

Get the binding for a variable.

Parameters:

  | name | The name of the requested variable.

Returns:
  The binding for the requested variable or and invalid node if the bindings do not contain the variable.

\sa QueryResultIterator.binding(const QString&) const.
