## Method Documentation

__init__ | ( | self, |
|  | Akonadi.Entity | other
| ) |  |  |

Creates an entity from an other entity.

addAttribute | ( | self, |
|  | Akonadi.Attribute | attribute
| ) |  |  |

Adds an attribute to the entity.

If an attribute of the same type name already exists, it is deleted and replaced with the new one.

Parameters:

  | attribute | The new attribute.

Note:
  The entity takes the ownership of the attribute.

Akonadi.Attribute attribute | ( | self, |
|  | QByteArray | name
| ) |  |  |

Returns the attribute of the requested type or 0 if it is not available.

[Akonadi.Attribute] attributes | ( |  | self ) |

Returns a list of all attributes of the entity.

clearAttributes | ( |  | self ) |

Removes and deletes all attributes of the entity.

bool hasAttribute | ( | self, |
|  | QByteArray | name
| ) |  |  |

Returns whether the entity has an attribute of the requested type.

long id | ( |  | self ) |

Returns the unique identifier of the entity.

bool isValid | ( |  | self ) |

Returns whether the entity is valid.

bool operator != | ( | self, |
|  | Akonadi.Entity | other
| ) |  |  |

Returns whether the entity's id does not equal the id of the other entity.

bool operator == | ( | self, |
|  | Akonadi.Entity | other
| ) |  |  |

Returns whether the entity's id equals the id of the other entity.

Akonadi.Collection parentCollection | ( |  | self ) |

Returns a reference to the parent collection of this object.

Note:
  This will of course only return a useful value if it was explictly retrieved from the Akonadi server.

Since:
  4.4

QString remoteId | ( |  | self ) |

Returns the remote id of the entity.

QString remoteRevision | ( |  | self ) |

Returns the remote revision of the entity.

Note:
  This method is supposed to be used by resources only.

Since:
  4.5

removeAttribute | ( | self, |
|  | QByteArray | name
| ) |  |  |

Removes and deletes the attribute of the requested type.

setId | ( | self, |
|  | long | identifier
| ) |  |  |

Sets the unique identifier of the entity.

setParentCollection | ( | self, |
|  | Akonadi.Collection | parent
| ) |  |  |

Set the parent collection of this object.

Note:
  Calling this method has no immediate effect for the object itself, such as being moved to another collection. It is mainly relevant to provide a context for RID-based operations inside resources.

Parameters:

  | parent | The parent collection.

Since:
  4.4

setRemoteId | ( | self, |
|  | QString | id
| ) |  |  |

Sets the remote id of the entity.

setRemoteRevision | ( | self, |
|  | QString | revision
| ) |  |  |

Sets the remote revision of the entity.

The remote revision can be used by resources to store some revision information of the backend to detect changes there.

Note:
  This method is supposed to be used by resources only.

Since:
  4.5
