public class LongField
extends com.vaadin.flow.component.textfield.AbstractNumberField<LongField, Long>

Long-valued sibling of Vaadin's IntegerField. Extends AbstractNumberField with a Long type parameter and a Long.parseLong(String, int) parser; shares the vaadin-integer-field web component so the client side still rejects decimals and shows the familiar spinner-arrow chrome.

Lives in :surrogates as a plain Vaadin component — no Swing surface, no mixin. Introduced to back SJSpinner when the installed SpinnerNumberModel carries a Long value without falling back to NumberField's double-mantissa rounding, but general-purpose: any Vaadin code needing a long-typed numeric field can use it directly.

Client-side precision: values up to 2⁵³ round-trip exactly through the browser's native numeric input (JS numbers are IEEE-754 doubles; integer-valued doubles stay exact up to 2⁵³). Longs outside that range display with mantissa rounding on the wire, but the server-side parser (unchanged Long.parseLong(String, int) on the string form delivered via _inputElementValue) sees the exact text the browser rendered, so round-trip precision depends on how browsers format long integers — which today is exact for all values the browser accepts via input[type=number].

Absolute min/max passed to the superclass use Long.MIN_VALUE / Long.MAX_VALUE cast to double (precision-lossy at the extremes, but the superclass removes those properties from the DOM immediately after initialisation — they only matter as signal defaults until a caller explicitly setMin / setMax).

Method Details

setMin

public void setMin(long min)

Sets the minimum value for the field. Mirrors IntegerField.setMin but with a long argument. Routes to AbstractNumberField's double-typed setter — precision is exact within [-2⁵³, 2⁵³] and lossy beyond that.

getMin

public long getMin()

setMax

public void setMax(long max)

getMax

public long getMax()

setStep

public void setStep(long step)

Sets the spinner-arrow step. Mirrors IntegerField.setStep's positive-only contract — zero / negative throws IAE, matching the web component's expectation that step is strictly positive.

getStep

public long getStep()
