API reference - Class LayerPropertiesNodeNotation used in Ruby API documentation Description: A layer properties node structure Class hierarchy: LayerPropertiesNode » LayerProperties
This class is derived from LayerProperties. Objects of this class are used in the hierarchy of layer views that are arranged in a tree while the LayerProperties object reflects the properties of a single node. Public constructors

Detailed description[const] bool !=(const LayerPropertiesNode other)Description: Inequality
[const] bool ==(const LayerPropertiesNode other)Description: Equality
void _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. LayerPropertiesNode ptr add_child(const LayerProperties child)Description: Add a child entry
This method allows to build a layer properties tree by adding children to node objects. It returns a reference to the node object created. This method was introduced in version 0.22. void assign(const LayerPropertiesNode other)Description: Assigns another object to self [const] DBox bboxDescription: Compute the bbox of this layer
This takes the layout and path definition (supported by the given default layout or path, if no specific is given). The node must have been attached to a view to make this operation possible. void clear_childrenDescription: Clears all children This method was introduced in version 0.22. 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 LayerPropertiesNode ptr dupDescription: Creates a copy of self [const] LayerPropertiesNode flatDescription: return the "flattened" (effective) layer properties node for this node This method returns a LayerPropertiesNode object that is not embedded into a hierarchy. This object represents the effective layer properties for the given node. In particular, all 'local' properties are identical to the 'real' properties. Such an object can be used as a basis for manipulations. Unlike the name suggests, this node will still contain a hierarchy of nodes below if the original node did so. [const] bool has_children?Description: Test, if there are children [const] unsigned int idDescription: Obtain the unique ID Each layer properties node object has a unique ID that is created when a new LayerPropertiesNode object is instantiated. The ID is copied when the object is copied. The ID can be used to identify the object irregardless of it's content. [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 LayerPropertiesNode ptr newDescription: Creates a new object of this class Python specific notes:This method is the default initializer of the object |
