Constructor Detail

FileTreeDataProvider

public FileTreeDataProvider(java.io.File... rootFiles)

Constructs file tree data provider with the specified files as root.

Parameters:

rootFiles - tree root files

FileTreeDataProvider

public FileTreeDataProvider(java.util.List<java.io.File> rootFiles)

Constructs file tree data provider with the specified files as root.

Parameters:

rootFiles - tree root files

FileTreeDataProvider

public FileTreeDataProvider(com.alee.utils.compare.Filter<FileTreeNode> filter,
                            java.io.File... rootFiles)

Constructs file tree data provider with the specified files as root.

Parameters:

filter - tree nodes filter

rootFiles - tree root files

FileTreeDataProvider

public FileTreeDataProvider(com.alee.utils.compare.Filter<FileTreeNode> filter,
                            java.util.List<java.io.File> rootFiles)

Constructs file tree data provider with the specified files as root.

Parameters:

filter - tree nodes filter

rootFiles - tree root files

Method Detail

getRoot

public FileTreeNode getRoot()

Description copied from interface: AsyncTreeDataProvider

Returns asynchronous tree root node. This request uses the EDT and should be processed quickly.

Returns:

root node

loadChildren

public void loadChildren(FileTreeNode parent,
                         ChildrenListener<FileTreeNode> listener)

Description copied from interface: AsyncTreeDataProvider

Starts loading child nodes for the specified asynchronous tree node. When you finish loading children for the specified node or you failed to load them, simply inform the listener about that. This request uses a separate thread and might take a lot of time to process without having any UI issues.

Parameters:

parent - parent node

listener - children loading progress listener

getRootChildren

protected java.util.List<FileTreeNode> getRootChildren()

Returns root child nodes.

Returns:

root child nodes

getFileChildren

public java.util.List<FileTreeNode> getFileChildren(FileTreeNode node)

Returns child nodes for specified node.

Parameters:

node - parent node

Returns:

child nodes

getChildrenFilter

public com.alee.utils.compare.Filter<FileTreeNode> getChildrenFilter(FileTreeNode node)

Description copied from interface: AsyncTreeDataProvider

Returns child nodes filter for the specified asynchronous tree node. No filtering applied to children in case null is returned.

Specified by:

getChildrenFilter in interface AsyncTreeDataProvider<FileTreeNode>

Overrides:

getChildrenFilter in class AbstractAsyncTreeDataProvider<FileTreeNode>

Parameters:

node - parent node

Returns:

child nodes filter

isLeaf

public boolean isLeaf(FileTreeNode node)

Description copied from class: AbstractAsyncTreeDataProvider

Returns false by default to allow children load requests. It is recommended to override this behavior if you can easily determine whether node is leaf or not.

Specified by:

isLeaf in interface AsyncTreeDataProvider<FileTreeNode>

Overrides:

isLeaf in class AbstractAsyncTreeDataProvider<FileTreeNode>

Parameters:

node - node

Returns:

false
