Constructor Summary
`DepthSelector()` Creates a new `DepthSelector` instance.

Method Summary
`boolean` `isSelected(java.io.File basedir, java.lang.String filename, java.io.File file)` The heart of the matter.
`void` `setMax(int max)` The minimum depth below the basedir before a file is selected.
`void` `setMin(int min)` The minimum depth below the basedir before a file is selected.
`void` `setParameters(Parameter[] parameters)` When using this as a custom selector, this method will be called.
`java.lang.String` `toString()` Basic DataType toString().
`void` `verifySettings()` Checks to make sure all settings are kosher.

Field Detail

### min

    public int min

  min attribute

### max

    public int max

  max attribute

### MIN_KEY

    public static final java.lang.String MIN_KEY

  Used for parameterized custom selector

  See Also:
    Constant Field Values

### MAX_KEY

    public static final java.lang.String MAX_KEY

  Used for parameterized custom selector

  See Also:
    Constant Field Values

Constructor Detail

### DepthSelector

    public DepthSelector()

  Creates a new `DepthSelector` instance.

Method Detail

### toString

    public java.lang.String toString()

  Description copied from class: `DataType`
  Basic DataType toString().

  Overrides:
    `toString` in class `DataType`
  Returns:
    a string describing this object

### setMin

    public void setMin(int min)

  The minimum depth below the basedir before a file is selected.

  Parameters:
    `min` - minimum directory levels below basedir to go

### setMax

    public void setMax(int max)

  The minimum depth below the basedir before a file is selected.

  Parameters:
    `max` - maximum directory levels below basedir to go

### setParameters

    public void setParameters(Parameter[] parameters)

  When using this as a custom selector, this method will be called. It translates each parameter into the appropriate setXXX() call.

  Specified by:
    `setParameters` in interface `Parameterizable`
  Overrides:
    `setParameters` in class `BaseExtendSelector`
  Parameters:
    `parameters` - the complete set of parameters for this selector

### verifySettings

    public void verifySettings()

  Checks to make sure all settings are kosher. In this case, it means that the max depth is not lower than the min depth.

  Overrides:
    `verifySettings` in class `BaseSelector`

### isSelected

    public boolean isSelected(java.io.File basedir,
                              java.lang.String filename,
                              java.io.File file)

  The heart of the matter. This is where the selector gets to decide on the inclusion of a file in a particular fileset. Most of the work for this selector is offloaded into SelectorUtils, a static class that provides the same services for both FilenameSelector and DirectoryScanner.

  Specified by:
    `isSelected` in interface `FileSelector`
  Specified by:
    `isSelected` in class `BaseExtendSelector`
  Parameters:
    `basedir` - the base directory the scan is being done from
    `filename` - is the name of the file to check
    `file` - is a java.io.File object the selector can use
  Returns:
    whether the file should be selected or not
