                                   ChildRules rules)

RuledDirectoryEntryViewImpl

public RuledDirectoryEntryViewImpl(TreeView treeView,
                                   TreeNode root,
                                   ChildRules rules)

Method Detail

getDirectoryEntryView

protected DirectoryEntryView getDirectoryEntryView()

getDirectoryEntryEditor

public DirectoryEntryEditor getDirectoryEntryEditor()

Return the directory entry editor for this view.

Specified by:

getDirectoryEntryEditor in interface DirectoryEntryView

Returns:

the DirectoryEntryEditor instance

lookup

public DirectoryEntry lookup(java.lang.String path)

Lookup the node referenced by the relative path in this view. Depending upon the implementation, this method may return a null reference if a node with the specified path is not found.

Specified by:

lookup in interface DirectoryEntryView

Parameters:

path - the path of the desired node specified in terms of this view (i.e., the result of calling getPath() on this view with the returned node as the parameter should result in the same value as path); may not be null or zero-length

Returns:

the node referenced by the specified path, or null if no such node exists

Throws:

java.lang.AssertionError - if the path is null or zero-length

lookup

public DirectoryEntry lookup(java.lang.String path,
                             java.lang.String separator)

Lookup the node referenced by the relative path in this view, but specify a separator. This method allows the lookup of a path with a different separator than used by this view. Depending upon the implementation, this method may return a null reference if a node with the specified path is not found.

Specified by:

lookup in interface DirectoryEntryView

Parameters:

path - the path of the desired node specified in terms of this view (i.e., the result of calling getPath() on this view with the returned node as the parameter should result in the same value as path); may not be null or zero-length

separater - the string used to separate the components of a name.

Returns:

the node referenced by the specified path, or null if no such node exists

Throws:

java.lang.AssertionError - if the path is null or zero-length
