Constructor Detail

### DateSelector

    public DateSelector()

  Creates a new `DateSelector` 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

### setMillis

    public void setMillis(long millis)

  Set the time; for users who prefer to express time in ms since 1970.

  Parameters:
    `millis` - the time to compare file's last modified date to, expressed in milliseconds.

### getMillis

    public long getMillis()

  Returns the millisecond value the selector is set for.

  Returns:
    the millisecond value.

### setDatetime

    public void setDatetime(java.lang.String dateTime)

  Sets the date. The user must supply it in MM/DD/YYYY HH:MM AM_PM format, unless an alternate pattern is specified via the pattern attribute.

  Parameters:
    `dateTime` - a formatted date `String`.

### setCheckdirs

    public void setCheckdirs(boolean includeDirs)

  Set whether to check dates on directories.

  Parameters:
    `includeDirs` - whether to check the timestamp on directories.

### setGranularity

    public void setGranularity(int granularity)

  Sets the number of milliseconds leeway we will give before we consider a file not to have matched a date.

  Parameters:
    `granularity` - the number of milliseconds leeway.

### setWhen

    public void setWhen(DateSelector.TimeComparisons tcmp)

  Sets the type of comparison to be done on the file's last modified date.

  Parameters:
    `tcmp` - The comparison to perform, an EnumeratedAttribute.

### setWhen

    public void setWhen(TimeComparison t)

  Set the comparison type.

  Parameters:
    `t` - TimeComparison object.

### setPattern

    public void setPattern(java.lang.String pattern)

  Sets the pattern to be used for the SimpleDateFormat.

  Parameters:
    `pattern` - the pattern that defines the date format.

### 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()

  This is a consistency check to ensure the selector's required values have been set.

  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.

  Specified by:
    `isSelected` in interface `FileSelector`
  Specified by:
    `isSelected` in class `BaseExtendSelector`
  Parameters:
    `basedir` - the base directory from which the scan is being performed.
    `filename` - is the name of the file to check.
    `file` - is a java.io.File object the selector can use.
  Returns:
    whether the file is selected.
