Constructor Detail

FileBranch

public FileBranch(File dir)

Constructs a branch from a File object representing an existing directory.

Parameters:

dir - directory

Throws:

IllegalArgumentException - if dir is not a directory

Method Detail

getChildren

public Node[] getChildren()

Description copied from interface: Branch

Returns the array of child nodes belonging to this branch. All the returned values represent file objects which actuallly exist in the filesystem.

Specified by:

getChildren in interface Branch

Returns:

child nodes of this one

createNode

public Node createNode(String location)

Description copied from interface: Branch

Attempts to construct a new node in the context of this one. The new item may represent a new or an existing node in the filesystem. This call should not in itself perform any write operations on the filesystem (such as creating a node which doesn't currently exist), though a subsequent Leaf.getOutputStream() call may do so.

The returned node will typically be a child of this branch, but need not be, for instance if name is interpreted as an absolute path.

If the named node cannot be created, null may be returned.

Specified by:

createNode in interface Branch

Parameters:

location - name of a node in the context of this branch

Returns:

node representing the location of an existing or new node

isHidingEnabled

public boolean isHidingEnabled()

Indicates whether files marked as hidden by the default FileSystemView are shown or not.

Returns:

true if hidden files are not shown

setHidingEnabled

public void setHidingEnabled(boolean hiding)

Sets whether files marked as hidden by the default FileSystemView are shown or not. The default is true.

Parameters:

hiding - true to hide hidden files
