Constructor Detail

### PopulateRootOperation

    public PopulateRootOperation(Object rootObject,
                                 IImportStructureProvider structureProvider)

  Create a new `PopulateFilesOperation`.

Parameters:
  `rootObject` - the object to be populated
  `structureProvider` - the object that defines how we are to populate it.

Method Detail

### createElement

    protected FileSystemElement createElement(FileSystemElement parent,
                                              Object fileSystemObject)
                                       throws InterruptedException

  Creates and returns a `FileSystemElement` if the specified file system object merits one. The criteria for this are: - if the file system object is a container then it must have either a child container or an associated file - if the file system object is a file then it must have an extension suitable for selection

  Overrides:
    `createElement` in class `SelectFilesOperation`
  Throws:
    `InterruptedException`

### createElement

    protected FileSystemElement createElement(FileSystemElement parent,
                                              Object fileSystemObject,
                                              int depth)
                                       throws InterruptedException

  Creates and returns a `FileSystemElement` if the specified file system object merits one. The criteria for this are: - if the file system object is a container then it must have either a child container or an associated file - if the file system object is a file then it must have an extension suitable for selection recurse down for depth to populate children

  Throws:
    `InterruptedException`
