    markAsDirty - true if the connector should automatically be marked dirty, false otherwise
    
    Returns:
    
    The shared state for this connector. Never null.

    AbstractClientConnector.getState()
  - doSetValue
```
protected void doSetValue(T value)
```
    Description copied from class: AbstractField
    
    Sets the value of this field. May do sanitization or throw IllegalArgumentException if the value is invalid. Typically saves the value to shared state.
    
    Specified by:
    
    doSetValue in class AbstractField<T extends Temporal & TemporalAdjuster & Serializable & Comparable<? super T>>
    
    Parameters:
    
    value - the new value of the field
  - getDatePart
```
protected abstract int getDatePart(T date,
                                   R resolution)
```
    Returns a date integer value part for the given date for the given resolution.
    
    Parameters:
    
    date - the given date, can be null
    
    resolution - the resolution to extract a value from the date by, not null
    
    Returns:
    
    the integer value part of the date by the given resolution
  - buildDate
```
protected abstract T buildDate(Map<R,Integer> resolutionValues)
```
    Builds date by the given resolutionValues which is a map whose keys are resolution and integer values.
    This is the opposite to getDatePart(Temporal, Enum).
    
    Parameters:
    
    resolutionValues - date values to construct a date
    
    Returns:
    
    date built from the given map of date values
  - getRangeValidator
```
protected abstract RangeValidator<T> getRangeValidator()
```
    Returns a custom date range validator which is applicable for the type T.
    
    Returns:
    
    the date range validator
  - convertFromDate
```
protected abstract T convertFromDate(Date date)
```
    Converts Date to date type T.
    
    Parameters:
    
    date - a date to convert
    
    Returns:
    
    object of type T representing the date
  - convertToDate
```
protected abstract Date convertToDate(T date)
```
    Converts the object of type T to Date.
    This is the opposite to convertFromDate(Date).
    
    Parameters:
    
    date - the date of type T
    
    Returns:
    
    converted date of type Date
  - getDefaultValidator
```
public Validator<T> getDefaultValidator()
```
    Description copied from interface: HasValue
    
    Returns a validator that checks the internal state of the HasValue. This should be overridden for components with internal value conversion or validation, e.g. when the user is providing a string that has to be parsed into a date. An invalid input from user will be exposed to a Binder and can be seen as a validation failure.
    
    Specified by:
    
    getDefaultValidator in interface HasValue<T extends Temporal & TemporalAdjuster & Serializable & Comparable<? super T>>
    
    Returns:
    
    internal state validator
    
    See Also:
    
    Binder.validate()
  - setDateStyle
```
public void setDateStyle(LocalDate date,
                         String styleName)
```
    Sets a custom style name for the given date's calendar cell. Setting the style name will override any previous style names that have been set for that date, but can contain several actual style names separated by space. Setting the custom style name null will only remove the previous custom style name.
    
    This logic is entirely separate from AbstractComponent.setStyleName(String)
    
    Usage examples:
    setDateStyle(LocalDate.now(), "teststyle");
    setDateStyle(LocalDate.now(), "teststyle1 teststyle2");
    
    Parameters:
    
    date - which date cell to modify, not null
    
    styleName - the custom style name(s) for given date, null to clear custom style name(s)
    
    Since:
    
    8.3
  - getDateStyle
```
public String getDateStyle(LocalDate date)
```
    Returns the custom style name that corresponds with the given date's calendar cell.
    
    Parameters:
    
    date - which date cell's custom style name(s) to return, not null
    
    Returns:
    
    the corresponding style name(s), if any, null otherwise
    
    Since:
    
    8.3
    
    See Also:
    
    setDateStyle(LocalDate, String)
  - getDateStyles
```
public Map<LocalDate,String> getDateStyles()
```
    Returns a map from dates to custom style names in each date's calendar cell.
    
    Returns:
    
    unmodifiable map from dates to custom style names in each date's calendar cell
    
    Since:
    
    8.3
    
    See Also:
    
    setDateStyle(LocalDate, String)
  - setAssistiveLabel
```
public void setAssistiveLabel(AbstractDateFieldState.AccessibleElement element,
                              String label)
```
    Sets the assistive label for a calendar navigation element. This sets the aria-label attribute for the element which is used by screen reading software.
    
    Parameters:
    
    element - the element for which to set the label. Not null.
    
    label - the assistive label to set
    
    Since:
    
    8.4
  - getAssistiveLabel
```
public void getAssistiveLabel(AbstractDateFieldState.AccessibleElement element)
```
    Gets the assistive label of a calendar navigation element.
    
    Parameters:
    
    element - the element of which to get the assistive label
    
    Since:
    
    8.4
