Initializes a new instance of the ValidationOpts class

Determines whether the specified object is equal to the current object.

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Serves as the default hash function.

Gets the Type of the current instance.

Creates a shallow copy of the current Object.

Check to see if validation options have been given. If not, create and instance with the default options and return that. This is useful for checking to see if a user has passed in validation options or not, since a new instance can't be a default parameter value.

Returns a string that represents the current object.

Allow a field to be empty, i.e. a zero length string - `''` (`true` - default) or require it to be non-zero length (`false`).

Error message should the validation fail

Require the field to be submitted (`false`) or not (`true` - default). When set to `true` the field does not need to be included in the list of parameters sent by the client - if set to `false` then it must be included. This option can be particularly useful in Editor as Editor will not set a value for fields which have not been submitted - giving the ability to submit just a partial list of options.
