BigDecimalField is an input field for handling decimal numbers with high precision. This field uses BigDecimal as the server-side value type, and only allows numeric input.

When setting values from the server-side, the scale of the provided BigDecimal is preserved in the presentation format shown to the user, as described in setValue(BigDecimal).

  • Method Details

    • getEmptyValue

      public BigDecimal getEmptyValue()
      Specified by:
      getEmptyValue in interface com.vaadin.flow.component.HasValue<com.vaadin.flow.component.AbstractField.ComponentValueChangeEvent<BigDecimalField,BigDecimal>,BigDecimal>
      Overrides:
      getEmptyValue in class com.vaadin.flow.component.AbstractField<BigDecimalField,BigDecimal>

    • setValue

      public void setValue(BigDecimal value)
      Sets the value of this field. If the new value is not equal to getValue(), fires a value change event.

      You can adjust how the value is presented in the field with the APIs provided by the value type BigDecimal. For example, you can change the number of decimal places with BigDecimal.setScale(int). This doesn't however restrict the user from entering values with different number of decimals. Note that BigDecimals are immutable, so their methods will return new instances instead of editing the existing ones. Scientific notation (such as 1e9) is turned into plain number format for the presentation.

      Specified by:
      setValue in interface com.vaadin.flow.component.HasValue<com.vaadin.flow.component.AbstractField.ComponentValueChangeEvent<BigDecimalField,BigDecimal>,BigDecimal>
      Overrides:
      setValue in class com.vaadin.flow.component.AbstractField<BigDecimalField,BigDecimal>
      Parameters:
      value - the new value

    • setModelValue

      protected void setModelValue(BigDecimal newModelValue, boolean fromClient)
      Overrides:
      setModelValue in class com.vaadin.flow.component.AbstractField<BigDecimalField,BigDecimal>

    • getValue

      public BigDecimal getValue()
      Returns the current value of the field. By default, the empty BigDecimalField will return null.
      Specified by:
      getValue in interface com.vaadin.flow.component.HasValue<com.vaadin.flow.component.AbstractField.ComponentValueChangeEvent<BigDecimalField,BigDecimal>,BigDecimal>
      Overrides:
      getValue in class com.vaadin.flow.component.AbstractField<BigDecimalField,BigDecimal>
      Returns:
      the current value.

    • setManualValidation

      public void setManualValidation(boolean enabled)
      Specified by:
      setManualValidation in interface com.vaadin.flow.component.HasValidation

    • 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.

    • getDefaultValidator

      public com.vaadin.flow.data.binder.Validator<BigDecimal> getDefaultValidator()
      Specified by:
      getDefaultValidator in interface com.vaadin.flow.data.binder.HasValidator<BigDecimal>

    • addValidationStatusChangeListener

      public com.vaadin.flow.shared.Registration addValidationStatusChangeListener(com.vaadin.flow.data.binder.ValidationStatusChangeListener<BigDecimal> listener)
      Specified by:
      addValidationStatusChangeListener in interface com.vaadin.flow.data.binder.HasValidator<BigDecimal>

    • setLocale

      public void setLocale(Locale locale)
      Sets the locale for this BigDecimalField. It is used to determine which decimal separator (the radix point) should be used.
      Parameters:
      locale - the locale to set, not null

    • getLocale

      public Locale getLocale()
      Gets the locale used by this BigDecimalField. It is used to determine which decimal separator (the radix point) should be used.
      Overrides:
      getLocale in class com.vaadin.flow.component.Component
      Returns:
      the locale of this field, never null

    • onAttach

      protected void onAttach(com.vaadin.flow.component.AttachEvent attachEvent)
      Overrides:
      onAttach in class com.vaadin.flow.component.Component
