Constructor Detail

Decimalbox

public Decimalbox()

Decimalbox

public Decimalbox(java.math.BigDecimal value)
           throws WrongValueException

Throws:

WrongValueException

Method Detail

getValue

public java.math.BigDecimal getValue()
                              throws WrongValueException

Returns the value (in BigDecimal), might be null unless a constraint stops it.

Throws:

WrongValueException - if user entered a wrong value

doubleValue

public double doubleValue()
                   throws WrongValueException

Returns the value in double. If null, zero is returned.

Throws:

WrongValueException

intValue

public int intValue()
             throws WrongValueException

Returns the value in integer. If null, zero is returned.

Throws:

WrongValueException

longValue

public long longValue()
               throws WrongValueException

Returns the value in long. If null, zero is returned.

Throws:

WrongValueException

shortValue

public short shortValue()
                 throws WrongValueException

Returns the value in short. If null, zero is returned.

Throws:

WrongValueException

setValue

public void setValue(java.math.BigDecimal value)
              throws WrongValueException

Sets the value (in BigDecimal).

Throws:

WrongValueException - if value is wrong

setValue

public void setValue(java.lang.String str)

getScale

public int getScale()

Returns the scale for the decimal number storing in this component, or AUTO if the scale is decided automatically (based on what user has entered).

Default: AUTO.

setScale

public void setScale(int scale)

Sets the scale for the decimal number storing in this component, or AUTO if the scale is decided automatically (based on what user has entered).

For example, set the scale of 1234.1234 to 2, the result will be 1234.12

Default: AUTO.

getZclass

public java.lang.String getZclass()

Description copied from class: HtmlBasedComponent

Returns the ZK Cascading Style class for this component. It usually depends on the implementation of the mold (AbstractComponent.getMold()).

Default: null (the default value depends on element).

HtmlBasedComponent.setZclass(java.lang.String)) will completely replace the default style of a component. In other words, the default style of a component is associated with the default value of HtmlBasedComponent.getZclass(). Once it is changed, the default style won't be applied at all. If you want to perform small adjustments, use HtmlBasedComponent.setSclass(java.lang.String) instead.

Overrides:

getZclass in class HtmlBasedComponent

See Also:

HtmlBasedComponent.getSclass()

marshall

protected java.lang.Object marshall(java.lang.Object value)

Description copied from class: InputElement

Marshall value to be sent to the client if needed.

Overrides it if the value to be sent to the client is not JSON Compatible.

Overrides:

marshall in class InputElement

Parameters:

value - the value to be sent to the client

Returns:

the marshalled value

unmarshall

protected java.lang.Object unmarshall(java.lang.Object value)

Description copied from class: InputElement

Unmarshall value returned from client if needed.

Overrides it if the value returned is not JSON Compatible.

Overrides:

unmarshall in class InputElement

Parameters:

value - the value returned from client

Returns:

the unmarshalled value

setRawValue

public void setRawValue(java.lang.Object value)

Description copied from class: InputElement

Sets the raw value directly. The caller must make sure the value is correct (or intend to be incorrect), because this method doesn't do any validation.

If you feel confusing with setValue, such as Textbox.setValue(java.lang.String), it is usually better to use setValue instead. This method is reserved for developer that really want to set an 'illegal' value (such as an empty string to a textbox with no-empty constraint).

Note: since 3.0.1, the value will be re-validate again if InputElement.getText() or others (such as Intbox.getValue()) is called. In other words, it is assumed that the specified value is not validated yet -- the same state when this component is created. If you want to avoid the re-validation, you have to invoke InputElement.clearErrorMessage().

Like setValue, the result is returned back to the server by calling InputElement.getText().

Overrides:

setRawValue in class InputElement

See Also:

InputElement.getRawValue()

coerceFromString

protected java.lang.Object coerceFromString(java.lang.String value)
                                     throws WrongValueException

Description copied from class: InputElement

Coerces the value passed to InputElement.setText(java.lang.String).

Deriving note:
If you want to store the value in other type, say BigDecimal, you have to override InputElement.coerceToString(java.lang.Object) and InputElement.coerceFromString(java.lang.String) to convert between a string and your targeting type.

Moreover, when Textbox is called, it calls this method with value = null. Derives shall handle this case properly.

Specified by:

coerceFromString in class InputElement

Throws:

WrongValueException

coerceToString

protected java.lang.String coerceToString(java.lang.Object value)

Description copied from class: InputElement

Coerces the value passed to InputElement.setText(java.lang.String).

Default: convert null to an empty string.

Deriving note:
If you want to store the value in other type, say BigDecimal, you have to override InputElement.coerceToString(java.lang.Object) and InputElement.coerceFromString(java.lang.String) to convert between a string and your targeting type.

Specified by:

coerceToString in class InputElement

renderProperties

protected void renderProperties(ContentRenderer renderer)
                         throws java.io.IOException

Description copied from class: HtmlBasedComponent

Renders the content of this component, excluding the enclosing tags and children.

See also ZK Client-side Reference: Property Rendering

Overrides:

renderProperties in class NumberInputElement

Throws:

java.io.IOException

getPropertyAccess

public PropertyAccess getPropertyAccess(java.lang.String prop)

Description copied from interface: ComponentCtrl

Returns the corresponding property access object from the given property name, if any.

Specified by:

getPropertyAccess in interface ComponentCtrl

Overrides:

getPropertyAccess in class NumberInputElement

Parameters:

prop - the name of the property

Returns:

null it means not to support for the property name.
