DateMidnight.Property ("The Adobe AEM Quickstart and Web Application.")

java.lang.Object
- org.joda.time.field.AbstractReadableInstantFieldProperty
- - org.joda.time.DateMidnight.Property

All Implemented Interfaces:

java.io.Serializable

Enclosing class:

DateMidnight
```
public static final class DateMidnight.Property
extends AbstractReadableInstantFieldProperty
```
DateMidnight.Property binds a DateMidnight to a DateTimeField allowing powerful datetime functionality to be easily accessed.
The simplest use of this class is as an alternative get method, here used to get the year '1972' (as an int) and the month 'December' (as a String).
```
 DateMidnight dt = new DateMidnight(1972, 12, 3);
 int year = dt.year().get();
 String monthStr = dt.monthOfYear().getAsText();
 
```
Methods are also provided that allow date modification. These return new instances of DateMidnight - they do not modify the original. The example below yields two independent immutable date objects 20 years apart.
```
 DateMidnight dt = new DateMidnight(1972, 12, 3);
 DateMidnight dt20 = dt.year().addToCopy(20);
 
```
Serious modification of dates (ie. more than just changing one or two fields) should use the MutableDateTime class.
DateMidnight.Property itself is thread-safe and immutable.
Since:

1.0

- Method Detail
  - getField
```
public DateTimeField getField()
```
    Gets the field being used.
    
    Specified by:
    
    getField in class AbstractReadableInstantFieldProperty
    
    Returns:
    
    the field
  - getDateMidnight
```
public DateMidnight getDateMidnight()
```
    Gets the datetime being used.
    
    Returns:
    
    the datetime
  - addToCopy
```
public DateMidnight addToCopy(int value)
```
    Adds to this field in a copy of this DateMidnight.
    The DateMidnight attached to this property is unchanged by this call. This operation is faster than converting a DateMidnight to a MutableDateTime and back again when setting one field. When setting multiple fields, it is generally quicker to make the conversion to MutableDateTime.
    
    Parameters:
    
    value - the value to add to the field in the copy
    
    Returns:
    
    a copy of the DateMidnight with the field value changed
    
    Throws:
    
    java.lang.IllegalArgumentException - if the value isn't valid
  - addToCopy
```
public DateMidnight addToCopy(long value)
```
    Adds to this field in a copy of this DateMidnight.
    The DateMidnight attached to this property is unchanged by this call. This operation is faster than converting a DateMidnight to a MutableDateTime and back again when setting one field. When setting multiple fields, it is generally quicker to make the conversion to MutableDateTime.
    
    Parameters:
    
    value - the value to add to the field in the copy
    
    Returns:
    
    a copy of the DateMidnight with the field value changed
    
    Throws:
    
    java.lang.IllegalArgumentException - if the value isn't valid
  - addWrapFieldToCopy
```
public DateMidnight addWrapFieldToCopy(int value)
```
    Adds to this field, possibly wrapped, in a copy of this DateMidnight. A wrapped operation only changes this field. Thus 31st January addWrapField one day goes to the 1st January.
    The DateMidnight attached to this property is unchanged by this call. This operation is faster than converting a DateMidnight to a MutableDateTime and back again when setting one field. When setting multiple fields, it is generally quicker to make the conversion to MutableDateTime.
    
    Parameters:
    
    value - the value to add to the field in the copy
    
    Returns:
    
    a copy of the DateMidnight with the field value changed
    
    Throws:
    
    java.lang.IllegalArgumentException - if the value isn't valid
  - setCopy
```
public DateMidnight setCopy(int value)
```
    Sets this field in a copy of the DateMidnight.
    The DateMidnight attached to this property is unchanged by this call. This operation is faster than converting a DateMidnight to a MutableDateTime and back again when setting one field. When setting multiple fields, it is generally quicker to make the conversion to MutableDateTime.
    
    Parameters:
    
    value - the value to set the field in the copy to
    
    Returns:
    
    a copy of the DateMidnight with the field value changed
    
    Throws:

public DateMidnight setCopy(java.lang.String text,
                            java.util.Locale locale)
```
    Sets this field in a copy of the DateMidnight to a parsed text value.
    The DateMidnight attached to this property is unchanged by this call. This operation is faster than converting a DateMidnight to a MutableDateTime and back again when setting one field. When setting multiple fields, it is generally quicker to make the conversion to MutableDateTime.
    
    Parameters:
    
    text - the text value to set
    
    locale - optional locale to use for selecting a text symbol
    
    Returns:

  - withMaximumValue
```
public DateMidnight withMaximumValue()
```
    Returns a new DateMidnight with this field set to the maximum value for this field.
    This operation is useful for obtaining a DateTime on the last day of the month, as month lengths vary.
```
 DateMidnight lastDayOfMonth = dt.dayOfMonth().withMaximumValue();
 
```
    The DateMidnight attached to this property is unchanged by this call.
    Returns:
    
    a copy of the DateMidnight with this field set to its maximum
    
    Since:
    
    1.2
