Hi all,
Here is the latest incarnation of my formatted output tag and supporting
classes. Source code, javadocs and tld files are included. BTW, I’ve started
packaging everything I consider as an extension to Struts under the same
package names, but starting with org.apache2.xxxxxx.
Comments anybody?
Regards
Ned
>From the docs:
A custom tag (bean2:writeformatted) that allows formatted output from beans.
A lot of this code has been appropriated from bean:write and bean:message,
and the usage reflects this. Tag properties scope, name, filter & property
work just like bean:write and locale & bundle work just like bean:message.
There are two new tag properties, nullkey and formatkey. Both of these refer
to strings in the message resource table.
WriteFormatted will work in this way:
· If the property value is null and nullkey is specified, then this is
lookup up into the resources and placed in the output stream.
· If the property value is a string, then this is used as a lookup into the
resources and placed in the output stream.
· If the property value is a primitive (int, double, etc) or one of the
objects based on these types, then value is formatted for output using a
NumberFormat object, with the format string either being looked up from the
resources by the formatkey property, or if this property is not specified,
with the default NumberFormat for this locale. (All NumberFormat's are
cached inside the FormatInfo object).
· If the property value implements LocaleFormatted then a FormatInfo object
is created and passed to the LocaleFormatted.toString(FormatInfo) method and
the object can decide how to render itself. The formatkey property is passed
over in the FormatInfo object, but it is up the property value object
whether it pays any attention to it,
The mechanism for dealing with objects that are not strings or which doesn't
implement LocaleFormatted is handled by the function getStringForObject.
This may be overridden in derived classes to provide conversion support for
legacy or 3rd party objects.
