<b>Subject: </b>[Engine-devel] Query regarding
ValidationUtils#validateInputs<br>
<br>
Hi,<br>
<br>
This is regarding the following validation method we have in
ValidationUtils:<br>
<br>
<i>public static <T extends VdcActionParametersBase>
ArrayList<String>
validateInputs(List<Class<?>>
validationGroupList, T parameters);</i><br>
<br>
I there any particular reason for supporting the validations
only on objects of classes derived from
VdcActionParametersBase? I guess this was done because this
method is primarily intended to validate the action parameters
passed to a BLL action, using the validation annotations on
the parameter class. However I think this method can be useful
for general use as well. e.g. I cannot add a "@Valid"
annotation on a "list" or a "map" in a parameter class. So I
need to iterate over the list/map, and validate each element
inside the loop. The validation inside the loop can also
utilize the above method if the restriction "extends
VdcActionParametersBase" is removed. This will allow me to do
the following in the canDoAction method:<br>
<br>
protected boolean canDoAction() {<br>
...<br>
for(GlusterBrickEntity brick :
getParameters().getGlusterVolume().getBricks()) {<br>
List<String> errors =
ValidationUtils.validateInputs(getValidationGroups(), brick);<br>
if(errors != null) {<br>
for(String error : errors) {<br>
addCanDoActionMessage(error);<br>
}<br>
}<br>
}<br>
...<br>
}<br>
<br>
Regards,<br>
Shireesh<br>

i don't think there is a reason to restrict only for
VdcActionParametersBase, roy what do you think?<br>
<br>
also you can use here<br>
getReturnValue().getCanDoActionMessages().addAll(errors);<br>
instead of going over on all errors.<br>

<br>
pls see SetupNetworksParameters.java for validating a list of
network interfaces.<br>
<br>
hibernate validator supports trivial object graphs and members that
are arrays, list and java.util.map implementations.<br>
If your code looks like that it should work. If you are using
special validation groups please add them to your command with
addValidationGroups.<br>
<br>
this should work:<br>
<br>
GlusterCommandParameters.java<br>
@Valid<br>
List<Bricks> bricks<br>
<br>
Bricks.java<br>
@NotNull<br>
Guid id<br>
