isValid

public boolean isValid(FormElement ui,

Description copied from interface: UserPropertyHandler

Check if this form is valid

Parameters:

ui - The form element previously created with the getFormElement method

formContext - Map containing some variables used in this form context, e.g. for cross form value checks. NULL to not use any form context variables

Returns:

true: the entered value is ok; false: the entered value is not accepted (Validation error)

See Also:

isValid

public boolean isValid(FormItem formItem,
                       java.util.Map formContext)

Description copied from interface: UserPropertyHandler

Checks if a form item for a property has a valid value and sets the appropriate error key if necessary. This is different from UserPropertyHandler.isValidValue(String, ValidationError, Locale) since it takes the value of the form item associated with this user property into account. Do all validations which depend on a form item here.

Parameters:

formItem - The flexi form item previously created with the addFormItem method

formContext - Map containing some variables used in this form context, e.g. for cross form value checks. NULL to not use any form context variables

Returns:

true: the entered value is ok; false: the entered value is not accepted (Validation error)

See Also:

UserPropertyHandler.isValid(org.olat.core.gui.components.form.flexible.FormItem, java.util.Map)

isValidValue

public boolean isValidValue(java.lang.String value,
                            ValidationError validationError,
                            java.util.Locale locale)

Description copied from interface: UserPropertyHandler

Checks if the given value is a valid value for this property (e.g. syntax checking). This is not connected to any form item, in contrast to UserPropertyHandler.isValid(FormItem, Map), so all validations which do not depend on a form item can be done here.

Parameters:

value - The value to be checked

validationError - Callback to get the error key in case of validation=false

Returns:

true: value is valid, false: value is invalid. Check validationError to get the error message
