API reference - Class ParentInstArrayNotation used in Ruby API documentation Description: A parent instance
A parent instance is basically an inverse instance: instead of pointing to the child cell, it is pointing to the parent cell and the transformation is representing the shift of the parent cell relative to the child cell. For memory performance, a parent instance is not stored as a instance but rather as a reference to a child instance and a reference to the cell which is the parent. The parent instance itself is computed on the fly. It is representative for a set of instances belonging to the same cell index. The special parent instance iterator takes care of producing the right sequence (Cell#each_parent_inst). See The Database API for more details about the database objects. Public constructors

Detailed descriptionvoid _createDescription: Ensures the C++ object is created Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created. void _destroyDescription: Explicitly destroys the object Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing. [const] bool _destroyed?Description: Returns a value indicating whether the object was already destroyed This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself. [const] bool _is_const_object?Description: Returns a value indicating whether the reference is a const reference This method returns true, if self is a const reference. In that case, only const methods may be called on self. void _manageDescription: Marks the object as managed by the script side. After calling this method on an object, the script side will be responsible for the management of the object. This method may be called if an object is returned from a C++ function and the object is known not to be owned by any C++ instance. If necessary, the script side may delete the object if the script's reference is no longer required. Usually it's not required to call this method. It has been introduced in version 0.24. void _unmanageDescription: Marks the object as no longer owned by the script side. Calling this method will make this object no longer owned by the script's memory management. Instead, the object must be managed in some other way. Usually this method may be called if it is known that some C++ object holds and manages this object. Technically speaking, this method will turn the script's reference into a weak reference. After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur. Usually it's not required to call this method. It has been introduced in version 0.24. void assign(const ParentInstArray other)Description: Assigns another object to self [const] Instance child_instDescription: Retrieve the child instance associated with this parent instance Starting with version 0.15, this method returns an Instance object rather than a CellInstArray reference. void createDescription: Ensures the C++ object is created Use of this method is deprecated. Use _create instead void destroyDescription: Explicitly destroys the object Use of this method is deprecated. Use _destroy instead [const] bool destroyed?Description: Returns a value indicating whether the object was already destroyed Use of this method is deprecated. Use _destroyed? instead [const] new ParentInstArray ptr dupDescription: Creates a copy of self [const] CellInstArray instDescription: Compute the inverse instance by which the parent is seen from the child [const] bool is_const_object?Description: Returns a value indicating whether the reference is a const reference Use of this method is deprecated. Use _is_const_object? instead [static] new ParentInstArray ptr newDescription: Creates a new object of this class Python specific notes:This method is the default initializer of the object [const] unsigned int parent_cell_indexDescription: Gets the index of the parent cell |
