Constructor Detail

FileSystemTreeModel.DirectoryNode

public FileSystemTreeModel.DirectoryNode(java.io.File file,
                                         boolean isHidden)

Method Detail

getFileLength

public long getFileLength()

Description copied from interface: FileInfo

Returns the length of the file. Returns -1 if the length has not (yet) been determined.

Specified by:

getFileLength in interface FileInfo

Overrides:

getFileLength in class FileSystemTreeModel.Node

getFileKind

public java.lang.String getFileKind()

Description copied from interface: FileInfo

Returns the kind of the file. Returns null if the kind has not (yet) been determined.

Specified by:

getFileKind in interface FileInfo

Overrides:

getFileKind in class FileSystemTreeModel.Node

invalidateChildren

public void invalidateChildren()

Marks this node as invalid. If the node denotes not a directory, nothing happens.

Overrides:

invalidateChildren in class FileSystemTreeModel.Node

lazyInvalidateChildren

public void lazyInvalidateChildren()

Marks the children of this node as invalid. This has only an effect, if this node denotes a directory.

Overrides:

lazyInvalidateChildren in class FileSystemTreeModel.Node

isValidatingChildren

public boolean isValidatingChildren()

Overrides:

isValidatingChildren in class FileSystemTreeModel.Node

stopValidationSubtree

public void stopValidationSubtree()

Overrides:

stopValidationSubtree in class FileSystemTreeModel.Node

invalidateTree

public void invalidateTree()

Marks this subtree as invalid.

Overrides:

invalidateTree in class FileSystemTreeModel.Node

validateChildren

public void validateChildren()

Validates this node if it is invalid. If this node is invalid, a worker thread is launched, which reads the directory denoted by this node and merges it with the existing children of this node. If the node denotes not a directory, nothing happens.

Overrides:

validateChildren in class FileSystemTreeModel.Node

autoValidateChildren

public void autoValidateChildren()

Validates this node if automatic validation is on and if it is invalid.

children

public java.util.Enumeration children()

Specified by:

children in interface javax.swing.tree.TreeNode

Overrides:

children in class FileSystemTreeModel.Node

getAllowsChildren

public boolean getAllowsChildren()

Specified by:

getAllowsChildren in interface javax.swing.tree.TreeNode

Overrides:

getAllowsChildren in class FileSystemTreeModel.Node

getChildAt

public javax.swing.tree.TreeNode getChildAt(int childIndex)

Specified by:

getChildAt in interface javax.swing.tree.TreeNode

Overrides:

getChildAt in class FileSystemTreeModel.Node

getChildCount

public int getChildCount()

Specified by:

getChildCount in interface javax.swing.tree.TreeNode

Overrides:

getChildCount in class FileSystemTreeModel.Node

getIndex

public int getIndex(javax.swing.tree.TreeNode node)

Specified by:

getIndex in interface javax.swing.tree.TreeNode

Overrides:

getIndex in class FileSystemTreeModel.Node

insert

public void insert(javax.swing.tree.MutableTreeNode newChild,
                   int childIndex)

Specified by:

insert in interface javax.swing.tree.MutableTreeNode

Overrides:

insert in class FileSystemTreeModel.Node

isLeaf

public boolean isLeaf()

Specified by:

isLeaf in interface javax.swing.tree.TreeNode

Overrides:

isLeaf in class FileSystemTreeModel.Node

remove

public void remove(javax.swing.tree.MutableTreeNode aChild)

Specified by:

remove in interface javax.swing.tree.MutableTreeNode

Overrides:

remove in class FileSystemTreeModel.Node

remove

public void remove(int childIndex)

Specified by:

remove in interface javax.swing.tree.MutableTreeNode

Overrides:

remove in class FileSystemTreeModel.Node
