        int getNodesCount()
        Replies the number of nodes in this way.
        Returns:
        the number of nodes in this way.

      • isEmpty

        default boolean isEmpty()
        Determines if this way is empty, i.e. it has no nodes.
        Returns:
        true if this way is empty, i.e. it has no nodes

        16119

      • getRealNodesCount

        default int getRealNodesCount()
        Replies the real number of nodes in this way (full number of nodes minus one if this way is closed)
        Returns:
        the real number of nodes in this way.

      • getNode

        N getNode​(int index)
        Replies the node at position index.
        Parameters:
        index - the position
        Returns:
        the node at position index
        Throws:
        java.lang.ArrayIndexOutOfBoundsException - if index < 0 or index >= getNodesCount()

        1862, 13717 (IWay)

      • getNodes

        java.util.List<N> getNodes()
        Returns the list of nodes in this way.
        Returns:
        the list of nodes in this way
        Since:
        1862, 13717 (IWay)

      • getChildren

        default java.util.List<N> getChildren()
        Description copied from interface: IPrimitive
        Get child primitives that are referred by this primitive. Relation: Members of the relation Way: Nodes used by the way Node: None
        Specified by:
        getChildren in interface IPrimitive
        Returns:
        List of child primitives

      • getNodeIds

        java.util.List<java.lang.Long> getNodeIds()
        Returns the list of node ids in this way.
        Returns:
        the list of node ids in this way
        Since:
        13717

      • getNodeId

        long getNodeId​(int idx)
        Returns id of the node at given index.
        Parameters:
        idx - node index
        Returns:
        id of the node at given index

      • setNodes

        void setNodes​(java.util.List<N> nodes)
        Set new list of nodes to way. This method is preferred to multiple calls to addNode/removeNode and similar methods because nodes are internally saved as array which means lower memory overhead but also slower modifying operations.
        Parameters:
        nodes - New way nodes. Can be null, in that case all way nodes are removed

      • isClosed

        boolean isClosed()
        Determines if this way is closed.
        Returns:
        true if this way is closed, false otherwise

      • compareTo

        default int compareTo​(IPrimitive o)
        Specified by:
        compareTo in interface java.lang.Comparable<N extends INode>

      • getDisplayName

        default java.lang.String getDisplayName​(NameFormatter formatter)
        Description copied from interface: IPrimitive
        Replies the display name of a primitive formatted by formatter
        Specified by:
        getDisplayName in interface IPrimitive
        Parameters:
        formatter - formatter to use
        Returns:
        the display name

      • firstNode

        N firstNode()
        Returns the first node of this way. The result equals getNode(0).
        Returns:
        the first node of this way
        Since:
        13922

      • lastNode

        N lastNode()
        Returns the last node of this way. The result equals getNode(getNodesCount - 1).
        Returns:
        the last node of this way
        Since:
        13922

      • isFirstLastNode

        boolean isFirstLastNode​(INode n)
        Replies true if the given node is the first or the last one of this way, false otherwise.
        Parameters:
        n - The node to test
        Returns:
        true if the n is the first or the last node, false otherwise.
        Since:
        13922

        Returns:
        true if the n is an inner node, false otherwise.
        Since:
        13922

      • hasIncompleteNodes

        default boolean hasIncompleteNodes()
        Replies true if this way has incomplete nodes, false otherwise.
        Returns:
