Overrides:

setLabel in class GeneratedVaadinTimePicker<TimePicker,LocalTime>

Parameters:

label - the String value to set

setValue

public void setValue(LocalTime value)

Description copied from interface: HasValue

Sets the value of this object. If the new value is not equal to getValue(), fires a value change event. May throw IllegalArgumentException if the value is not acceptable.

Implementation note: the implementing class should document whether null values are accepted or not, and override HasValue.getEmptyValue() if the empty value is not null.

Specified by:

setValue in interface HasValue<AbstractField.ComponentValueChangeEvent<TimePicker,LocalTime>,LocalTime>

Overrides:

setValue in class AbstractField<TimePicker,LocalTime>

Parameters:

value - the new value

getLabel

public String getLabel()

Parameters:

errorMessage - the String value to set

getErrorMessage

public String getErrorMessage()

Gets the current error message from the time picker.

Specified by:

getErrorMessage in interface HasValidation

Returns:

the current error message

setInvalid

public void setInvalid(boolean invalid)

Description copied from class: GeneratedVaadinTimePicker

Description copied from corresponding location in WebComponent:

Set to true if the value is invalid.

Specified by:

setInvalid in interface HasValidation

Overrides:

setInvalid in class GeneratedVaadinTimePicker<TimePicker,LocalTime>

Parameters:

invalid - the boolean value to set

isInvalid

public boolean isInvalid()

Gets the validity of the time picker output.

return true, if the value is invalid.

Specified by:

isInvalid in interface HasValidation

Returns:

the validity property from the time picker

setPlaceholder

public void setPlaceholder(String placeholder)

Description copied from class: GeneratedVaadinTimePicker

Description copied from corresponding location in WebComponent:

A placeholder string in addition to the label.

Overrides:

setPlaceholder in class GeneratedVaadinTimePicker<TimePicker,LocalTime>

Parameters:

placeholder - the String value to set

getPlaceholder

public String getPlaceholder()

Gets the placeholder of the time picker.

This property is not synchronized automatically from the client side, so the returned value may not be the same as in client side.

Returns:

the placeholder property of the time picker

setRequired

public void setRequired(boolean required)

Description copied from class: GeneratedVaadinTimePicker

Description copied from corresponding location in WebComponent:

Set to true to mark the input as required.

Overrides:

setRequired in class GeneratedVaadinTimePicker<TimePicker,LocalTime>

Parameters:

required - the boolean value to set

setRequiredIndicatorVisible

public void setRequiredIndicatorVisible(boolean requiredIndicatorVisible)

Description copied from interface: HasValue

Sets the required indicator visible or not.

If set visible, it is visually indicated in the user interface.

The method is intended to be used with Binder which does server-side validation. In case HTML element has its own (client-side) validation it should be disabled when setRequiredIndicatorVisible(true) is called and re-enabled back on setRequiredIndicatorVisible(false). It's responsibility of each component implementation to follow the contract so that the method call doesn't do anything else than show/hide the "required" indication. Usually components provide their own setRequired method which should be called in case the client-side validation is required.

Specified by:

setRequiredIndicatorVisible in interface HasValue<AbstractField.ComponentValueChangeEvent<TimePicker,LocalTime>,LocalTime>

Specified by:

setRequiredIndicatorVisible in interface HasValueAndElement<AbstractField.ComponentValueChangeEvent<TimePicker,LocalTime>,LocalTime>

Parameters:

requiredIndicatorVisible - true to make the required indicator visible, false if not

isRequired

public boolean isRequired()

Determines whether the time picker is marked as input required.

This property is not synchronized automatically from the client side, so the returned value may not be the same as in client side.

Returns:

true if the input is required, false otherwise

setStep

public void setStep(Duration step)

Sets the step property of the time picker using duration. It specifies the intervals for the displayed items in the time picker dropdown and also the displayed time format.

The set step needs to evenly divide a day or an hour and has to be larger than 0 milliseconds. By default, the format is hh:mm (same as * Duration.ofHours(1)

If the step is less than 60 seconds, the format will be changed to hh:mm:ss and it can be in hh:mm:ss.fff format, when the step is less than 1 second.

NOTE: If the step is less than 900 seconds, the dropdown is hidden.

NOTE: changing the step to a larger duration can cause a new HasValue.ValueChangeEvent to be fired if some parts (eg. seconds) is discarded from the value.

Parameters:

step - the step to set, not null and should divide a day or an hour evenly

getStep

public Duration getStep()

Gets the step of the time picker.

This property is not synchronized automatically from the client side, so the returned value may not be the same as in client side.

Returns:

the step property from the picker, unit seconds

addInvalidChangeListener

public Registration addInvalidChangeListener(ComponentEventListener<GeneratedVaadinTimePicker.InvalidChangeEvent<TimePicker>> listener)

Description copied from class: GeneratedVaadinTimePicker

Adds a listener for invalid-changed events fired by the webcomponent.

Overrides:

addInvalidChangeListener in class GeneratedVaadinTimePicker<TimePicker,LocalTime>

Parameters:

listener - the listener

Returns:

a Registration for removing the event listener

validate

protected void validate()

Performs server-side validation of the current value. This is needed because it is possible to circumvent the client-side validation constraints using browser development tools.

Overrides:

validate in class GeneratedVaadinTimePicker<TimePicker,LocalTime>

onAttach

protected void onAttach(AttachEvent attachEvent)

Description copied from class: Component

Called when the component is attached to a UI.

The default implementation does nothing.

This method is invoked before the AttachEvent is fired for the component.

Overrides:

onAttach in class Component

Parameters:

attachEvent - the attach event

setLocale

public void setLocale(Locale locale)

Set the Locale for the Time Picker. The displayed time will be formatted by the browser using the given locale.

By default, the locale is null until the component is attached to an UI, and then locale is set to UI.getLocale(), unless a locale has been explicitly set before that.

The time formatting is done in the browser using the Date.toLocaleTimeString() function.

If for some reason the browser doesn't support the given locale, the en-US locale is used.

NOTE: only the language + country/region codes are used. This means that the script and variant information is not used and supported. NOTE: timezone related data is not supported. NOTE: changing the locale does not cause a new HasValue.ValueChangeEvent to be fired.

Parameters:

locale - the locale set to the time picker, cannot be [@code null}

getLocale

public Locale getLocale()

Gets the Locale for this time picker.

By default, the locale is null until the component is attached to an UI, and then locale is set to UI.getLocale(), unless setLocale(Locale) has been explicitly called before that.

Overrides:

getLocale in class Component

Returns:

the locale used for this time picker

setMin
