public class CheckboxTag
- extends AbstractSingleCheckedElementTag
Databinding-aware JSP tag for rendering an HTML 'input'
element with a 'type' of 'checkbox'.
May be used in one of three different approaches depending on the
type of the bound value.
Approach One
When the bound value is of type Boolean then the 'input(checkbox)'
is marked as 'checked' if the bound value is true. The 'value'
attribute corresponds to the resolved value of the value property.
Approach Two
When the bound value is of type Collection then the 'input(checkbox)'
is marked as 'checked' if the configured value is present in
the bound Collection.
Approach Three
For any other bound value type, the 'input(checkbox)' is marked as 'checked'
if the the configured value is equal to the bound value.
