/**
* The {@linkplain #NORMAL normal} output element is replaced with a simple representation
* of the {@linkplain FormControl form control's} submission value(s).
*
* The implementation of this functionality is highly subjective, but provides a more aesthetic way of displaying a read-only version
* of a form without having to resort to using {@linkplain FormControl#isDisabled() disabled} controls.
*
* The representation is dependent on the {@linkplain FormControlType form control type}, and can be configured using the
* static properties of the {@link ConfigDisplayValue ConfigDisplayValue} nested class.
*
* Unless specified otherwise below, the {@linkplain #NORMAL normal} output element is
* replaced with a display value element having the {@linkplain Element#getName() name}
* specified in the static {@link ConfigDisplayValue#ElementName ConfigDisplayValue.ElementName} property
* (div by default).
* The attributes specified in the static {@link ConfigDisplayValue#AttributeNames ConfigDisplayValue.AttributeNames} list
* (id, class and style by default) are copied from
* the {@linkplain #NORMAL normal} output element into the
* display value element.
*
* Details of the content of the display value element or other representation of the
* control value are as follows:
*
*
* - {@link FormControlType#TEXT TEXT}, {@link FormControlType#FILE FILE}
*
- The content of the display value element is the
* {@linkplain CharacterReference#reencode(CharSequence) re-encoded} value of the
* {@linkplain #NORMAL normal} output element's
value attribute.
* - {@link FormControlType#TEXTAREA TEXTAREA}
*
- The content of the display value element is the content of the
TEXTAREA element
* re-encoded {@linkplain CharacterReference#encodeWithWhiteSpaceFormatting(CharSequence) with white space formatting}.
* - {@link FormControlType#CHECKBOX CHECKBOX}, {@link FormControlType#RADIO RADIO}
*
- The {@linkplain #NORMAL normal} output element is replaced with the
* un-encoded content specified in the {@link ConfigDisplayValue#CheckedHTML ConfigDisplayValue.CheckedHTML} or
* {@link ConfigDisplayValue#UncheckedHTML ConfigDisplayValue.UncheckedHTML} static property, depending on
* whether the {@linkplain #NORMAL normal} output element contains a
*
checked attribute.
* If the relevant static property has a value of null (the default), the
* output element is simply a {@linkplain FormControl#setDisabled(boolean) disabled}
* version of the form control.
* Attempting to determine which labels might apply to which checkbox or radio button, allowing only the
* selected controls to be displayed, would require a very complex and inexact algorithm, so is best left to the developer
* to implement if required.
* - {@link FormControlType#SELECT_SINGLE SELECT_SINGLE}, {@link FormControlType#SELECT_MULTIPLE SELECT_MULTIPLE}
*
- The content of the display value element is the
* {@linkplain CharacterReference#reencode(CharSequence) re-encoded} label of the currently selected option.
* In the case of a {@link FormControlType#SELECT_MULTIPLE SELECT_MULTIPLE} control, all labels of selected options
* are listed, separated by the text specified in the static
* {@link ConfigDisplayValue#MultipleValueSeparator ConfigDisplayValue.MultipleValueSeparator} property
* ("
, " by default).
* - {@link FormControlType#PASSWORD PASSWORD}
*
- The content of the display value element is the
* {@linkplain CharacterReference#encode(CharSequence) encoded} character specified in the
* {@link ConfigDisplayValue#PasswordChar ConfigDisplayValue.PasswordChar} static property ('
*' by default),
* repeated n times, where n is the number of characters in the control's
* submission value.
* - {@link FormControlType#HIDDEN HIDDEN}
*
- The output element is {@linkplain #REMOVE removed} completely.
*
- {@link FormControlType#BUTTON BUTTON}, {@link FormControlType#SUBMIT SUBMIT}, {@link FormControlType#IMAGE IMAGE}
*
- The output element
* is a {@linkplain FormControl#setDisabled(boolean) disabled} version of the original form control.
*
*
* If the submission value of the control is null or an empty string,
* the display value element is given the un-encoded content specified in the
* {@link ConfigDisplayValue#EmptyHTML ConfigDisplayValue.EmptyHTML} static property.
