<H1><A NAME="5">5 Localizing error messages</A></H1>
|
|

<P> The library has a quite extensive set of error messages to give
|
|
|
30 |
hints and catch erroneous input to many of the controlling methods and
|
|
|
31 |
also do sanity check on the data to be plotted.</P>
|
|
|
32 |
<P> All error messages are collected in resource files which are
|
|
|
33 |
localized to a specific language. All resource files are located under
|
|
|
34 |
the "lang/" directory in the JpGraph installation directory. The
|
|
|
35 |
deafult locale to be used is defined in the configuration file with the
|
|
|
36 |
setting DEFAULT_ERR_LOCALE in the distribution this is set to English
|
|
|
37 |
locale.</P>
|
|
|
38 |
<P> The chosen locale is specified in the beginning of the script with a
|
|
|
39 |
call to the static method<I> JpGraphError::SetErrLocale()</I>. The
|
|
|
40 |
argument to this method is the ISO naming of the country/language to be
|
|
|
41 |
selected. For example to enable the special production locale the
|
|
|
42 |
following line should be added in the beginning of the script</P>
|
|
|
43 |
<PRE>
|
|
|
44 |
JpGraphError::SetErrLocale('prod');
|
|
|
45 |
</PRE>
|
|
|
46 |
If an unknown or unsupported locale is given the error message will
|
|
|
47 |
default to English.<HR NOSHADE>
