com.smartgwt.client.widgets.form.validator.Validator
A validator describes a check that should be performed on a value the user is trying to save.
Validators are specified for DataSource fields via the {@link com.smartgwt.client.data.DataSourceField#getValidators validators}property. Validators that need not be run on the server can also be specified for a specific {@link com.smartgwt.client.widgets.form.fields.FormItem} or {@link com.smartgwt.client.widgets.grid.ListGridField}.
Smart GWT supports a powerful library of {@link com.smartgwt.client.types.ValidatorType ValidatorTypes} which have identicalbehavior on both the client and the server.
Beyond this, custom validators can be defined on the client and custom validation logic added on the server. Note that the regexp and mask validator types are very flexible and can be used to perform virtually any kind of formatting check that doesn't involve some large external dataset.
Custom validators can be reused on the client by adding them to the global validator list, via the {@link com.smartgwt.client.widgets.form.validator.Validator#addValidator Validator.addValidator} method. @see com.smartgwt.client.types.ValidatorType
