All Implemented Interfaces:

java.io.Serializable

Enclosing class:

LocalDateTime
```
public static final class LocalDateTime.Property
extends AbstractReadableInstantFieldProperty
```
LocalDateTime.Property binds a LocalDateTime 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).
```
 LocalDateTime dt = new LocalDateTime(1972, 12, 3, 0, 0);
 int year = dt.year().get();
 String monthStr = dt.month().getAsText();
 
```
Methods are also provided that allow date modification. These return new instances of LocalDateTime - they do not modify the original. The example below yields two independent immutable date objects 20 years apart.
```
 LocalDateTime dt = new LocalDateTime(1972, 12, 3, 0, 0);
 LocalDateTime dt1920 = dt.year().setCopy(1920);
 
```
LocalDateTime.Property itself is thread-safe and immutable, as well as the LocalDateTime being operated on.

  - getField
```
public DateTimeField getField()
```
    Gets the field being used.
    
    Specified by:
    
    getField in class AbstractReadableInstantFieldProperty
    
    Returns:
    
    the field
  - getLocalDateTime
```
public LocalDateTime getLocalDateTime()
```
    Gets the LocalDateTime object linked to this property.
    
    Returns:
    
    the linked LocalDateTime
  - addToCopy
```
public LocalDateTime addToCopy(int value)
```
    Adds to this field in a copy of this LocalDateTime.
    The LocalDateTime attached to this property is unchanged by this call.
    
    Parameters:
    
    value - the value to add to the field in the copy
    
    Returns:
    
    a copy of the LocalDateTime with the field value changed
    
    Throws:
    
    java.lang.IllegalArgumentException - if the value isn't valid
  - addToCopy
```
public LocalDateTime addToCopy(long value)
```
    Adds to this field in a copy of this LocalDateTime.
    The LocalDateTime attached to this property is unchanged by this call.
    
    Parameters:
    
    value - the value to add to the field in the copy
    
    Returns:
    
    a copy of the LocalDateTime with the field value changed
    
    Throws:
    
    java.lang.IllegalArgumentException - if the value isn't valid
  - addWrapFieldToCopy
```
public LocalDateTime addWrapFieldToCopy(int value)
```
    Adds to this field, possibly wrapped, in a copy of this LocalDateTime. A field wrapped operation only changes this field. Thus 31st January addWrapField one day goes to the 1st January.
    The LocalDateTime attached to this property is unchanged by this call.
    
    Parameters:
    
    value - the value to add to the field in the copy
    
    Returns:
    
    a copy of the LocalDateTime with the field value changed
    
    Throws:
    
    java.lang.IllegalArgumentException - if the value isn't valid
  - setCopy
```
public LocalDateTime setCopy(int value)
```
    Sets this field in a copy of the LocalDateTime.
    The LocalDateTime attached to this property is unchanged by this call.
    
    Parameters:
    
    value - the value to set the field in the copy to
    
    Returns:
    
    a copy of the LocalDateTime with the field value changed
    
    Throws:
    
    java.lang.IllegalArgumentException - if the value isn't valid
  - setCopy
```
public LocalDateTime setCopy(java.lang.String text,
                             java.util.Locale locale)
```
    Sets this field in a copy of the LocalDateTime to a parsed text value.
    The LocalDateTime attached to this property is unchanged by this call.
    
    Parameters:
    
    text - the text value to set
    
    locale - optional locale to use for selecting a text symbol
    
    Returns:
    
    a copy of the LocalDateTime with the field value changed
    
    Throws:
    
    java.lang.IllegalArgumentException - if the text value isn't valid
  - setCopy
```
public LocalDateTime setCopy(java.lang.String text)

    java.lang.IllegalArgumentException - if the text value isn't valid
  - withMaximumValue
```
public LocalDateTime withMaximumValue()
```
    Returns a new LocalDateTime with this field set to the maximum value for this field.
    This operation is useful for obtaining a LocalDateTime on the last day of the month, as month lengths vary.
    LocalDateTime lastDayOfMonth = dt.dayOfMonth().withMaximumValue();
    
    The LocalDateTime attached to this property is unchanged by this call.
    Returns:
    
    a copy of the LocalDateTime with this field set to its maximum

```
public LocalDateTime withMinimumValue()
```
    Returns a new LocalDateTime with this field set to the minimum value for this field.
    The LocalDateTime attached to this property is unchanged by this call.
    
    Returns:
    
    a copy of the LocalDateTime with this field set to its minimum
  - roundFloorCopy
```
public LocalDateTime roundFloorCopy()
```
    Rounds to the lowest whole unit of this field on a copy of this LocalDateTime.
    For example, rounding floor on the hourOfDay field of a LocalDateTime where the time is 10:30 would result in new LocalDateTime with the time of 10:00.
    
    Returns:
    
    a copy of the LocalDateTime with the field value changed
  - roundCeilingCopy
```
public LocalDateTime roundCeilingCopy()
```
    Rounds to the highest whole unit of this field on a copy of this LocalDateTime.

    a copy of the LocalDateTime with the field value changed
  - roundHalfFloorCopy
```
public LocalDateTime roundHalfFloorCopy()
```
    Rounds to the nearest whole unit of this field on a copy of this LocalDateTime, favoring the floor if halfway.
    
    Returns:
    
    a copy of the LocalDateTime with the field value changed
  - roundHalfCeilingCopy
```
public LocalDateTime roundHalfCeilingCopy()
```
    Rounds to the nearest whole unit of this field on a copy of this LocalDateTime, favoring the ceiling if halfway.

    a copy of the LocalDateTime with the field value changed
  - roundHalfEvenCopy
```
public LocalDateTime roundHalfEvenCopy()
```
    Rounds to the nearest whole unit of this field on a copy of this LocalDateTime. If halfway, the ceiling is favored over the floor only if it makes this field's value even.
    
    Returns:
    
    a copy of the LocalDateTime with the field value changed
