public class ValidateOrder
extends ValidateMultipleFields

The <o:validateOrder> validates if the values of the given UIInput components as specified in the components attribute are in the order as specified by the type attribute which accepts the following values:

• lt (default): from least to greatest, without duplicates.
• lte: from least to greatest, allowing duplicates (equal values next to each other).
• gt: from greatest to least, without duplicates.
• gte: from greatest to least, allowing duplicates (equal values next to each other).

This validator has the additional requirement that the to-be-validated values must implement Comparable. This validator throws an IllegalArgumentException when one or more of the values do not implement it. Note that when this validator is placed before all of the components, then it will only compare the raw unconverted submitted string values, not the converted object values. If you need to compare by the converted object values, then you need to place this validator after all of the components.

The default message is

{0}: Please fill out the values of all those fields in order

For general usage instructions, refer ValidateMultipleFields documentation.

Method Detail

validateValues

public boolean validateValues(FacesContext context,
                              List<UIInput> components,
                              List<Object> values)

Validate if all values are in specified order.

Parameters:

context - The faces context to work with.

components - The input components whose values are to be validated.

values - The values of the input components to be validated.

Returns:

true if validation is successful, otherwise false (and thus show the message).

getType

public String getType()

Returns the ordering type to be used.

Returns:

The ordering type to be used.

setType

public void setType(String type)

Sets the ordering type to be used.

Parameters:

type - The ordering type to be used.
