Class FSBRootNode

  • All Implemented Interfaces:
    java.lang.Cloneable, java.lang.Comparable<GTreeNode>
    public class FSBRootNode
extends FSBNode
    A GTreeNode that represents the root of a GFileSystem, and keeps the filesystem pinned in memory with its FileSystemRef.

    The FileSystemRef is released when this node is dispose()d.

    Since GTreeNodes are cloned during GTree filtering, and this class has a reference to an external resource that needs managing, this class needs to keeps track of the original modelNode and does all state modification using the modelNode's context.

    • Method Detail

      • clone

        public GTreeNode clone()
                throws java.lang.CloneNotSupportedException
        Creates a clone of this node. The clone should contain a shallow copy of all the node's attributes except that the parent and children are null.
        Returns:
        the clone of this object.
        Throws:
        java.lang.CloneNotSupportedException - if some implementation prevents itself from being cloned.

      • dispose

        public void dispose()

      • getName

        public java.lang.String getName()
        Description copied from class: GTreeNode
        Returns the name of the node. If GTreeNode.getDisplayText() is not overridden, then this is also the text that will be displayed in the tree for that node. In general, the name of a node should not change. If the text displayed in the tree changes over time, override GTreeNode.getDisplayText().
        Overrides:
        getName in class FSBNode
        Returns:
        the name of the node

      • getToolTip

        public java.lang.String getToolTip()
        Description copied from class: GTreeNode
        Returns the string to be displayed as a tooltip when the user hovers the mouse on this node in the tree
        Overrides:
        getToolTip in class FSBNode
        Returns:
        the tooltip to be displayed

      • isLeaf

        public boolean isLeaf()
        Description copied from class: GTreeNode
        Returns true if this node never has children
        Specified by:
        isLeaf in class GTreeNode
        Returns:
        true if this node is a leaf

      • generateChildren

        public java.util.List<GTreeNode> generateChildren​(TaskMonitor monitor)
                                           throws CancelledException
        Description copied from class: GTreeSlowLoadingNode
        Subclass must implement this method to generate their children. This operation will always be performed in a background thread (i.e. Not the swing thread)
        Specified by:
        generateChildren in class GTreeSlowLoadingNode
        Parameters:
        monitor - a TaskMonitor for reporting progress and cancel notification.
        Returns:
        the list of children for this node.
        Throws:
        CancelledException - if the monitor is cancelled

      • getFSRL

        public FSRL getFSRL()
        Description copied from class: FSBNode
        Returns the FSRL of the filesystem object that this node represents.

        The root of filesystems will return a FSRLRoot.

        Specified by:
        getFSRL in class FSBNode
        Returns:
        FSRL of the filesystem object.

      • getParent

        public final GTreeNode getParent()
        Returns the parent of this node. Note: this method is deliberately not synchronized (See comments above)
        Returns:
        the parent of this node.

      • isRoot

        public final boolean isRoot()
        Returns true if this is a root node of a GTree
        Returns:
        true if this is a root node of a GTree

      • children

        protected final java.util.List<GTreeNode> children()

      • doSetChildrenAndFireEvent

        protected void doSetChildrenAndFireEvent​(java.util.List<GTreeNode> childList)
        Sets the children of this node to the given list of child nodes and fires the appropriate tree event to kick the tree to update the display. Note: This method must be called from the swing thread because it will notify the underlying JTree.
        Parameters:
        childList - the list of child nodes to assign as children to this node
        See Also:
        if calling from a background thread.

      • doSetChildren

        protected void doSetChildren​(java.util.List<GTreeNode> childList)
        Sets the children of this node to the given list of child nodes, but does not notify the tree. This method does not have to be called from the swing thread. It is intended to be used by background threads that want to populate all or part of the tree, but wait until the bulk operations are completed before notifying the tree.
        Parameters:
        childList - the list of child nodes to assign as children to this node

      • doAddNode

        protected void doAddNode​(GTreeNode node)
        Adds a node to this node's children. Must be called from the swing thread.
        Parameters:
        node - the node to add as a child to this node

      • doAddNode

        protected void doAddNode​(int index,
                         GTreeNode node)
        Adds a node to this node's children at the given index and notifies the tree. Must be called from the swing thread.
        Parameters:
        index - the index at which to add the new node
        node - the node to add as a child to this node

      • doRemoveNode

        protected void doRemoveNode​(GTreeNode node)
        Removes the node from this node's children and notifies the tree. Must be called from the swing thread.
        Parameters:
        node - the node to remove

      • doAddNodes

        protected void doAddNodes​(java.util.List<GTreeNode> nodes)
        Adds the given nodes to this node's children. Must be called from the swing thread.
        Parameters:
        nodes - the nodes to add to the children this node

      • isInProgress

        public final boolean isInProgress()
        Returns true if the node is in the process of loading its children. See GTreeSlowLoadingNode

      • isLoaded

        public boolean isLoaded()
        True if the children for this node have been loaded yet. Some GTree nodes are lazy in that they don't load their children until needed. Nodes that have the IN_PROGRESS node as it child is considered loaded if in the swing thread, otherwise they are considered not loaded.

        true if the children for this node have been loaded.
