parameters

public abstract String[] parameters

This "list" will represent the parameter the caller will send to the validation. Assuming you have this validation: @AsyncValidation("xxx") ValidationResult doValidate(@Option("value") String value, @Option("other") String other) And this model: public class MyModel { @Validable(value = "xxx", parameters = {".", "foo"}) @Option String something; @Option String foo; } This must call doValidate(something, foo). Syntax is the following:

• .: represents the decorated option (aka "this")
• ../foo: represents the

   foo
   

  option of the parent (if exists) of "."
• bar: represents the

   bar
   

  sibling option of the decorated field
• bar/dummy: represents the

   dummy
   

  option of the child bar of the decorated field

This syntax is close to path syntax but the important point is all the parameters are related to the decorated option.

Returns:

parameters for the validation.

Default:

"."
