getUserPropertyAsHTML

public java.lang.String getUserPropertyAsHTML(User user,
                                              java.util.Locale locale)

Specified by:

getUserPropertyAsHTML in interface UserPropertyHandler

Overrides:

getUserPropertyAsHTML in class AbstractUserPropertyHandler

Parameters:

user - the user for which we want to get the value

locale - the current users locale or NULL if default locale should be used.

Returns:

The value formatted in HTML or an empty String if no value exists

AbstractUserPropertyHandler.getUserPropertyAsHTML(org.olat.core.id.User, java.util.Locale)

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.

Specified by:

isValidValue in interface ItemValidatorProvider

Specified by:

isValidValue in interface UserPropertyHandler

Overrides:

isValidValue in class Generic127CharTextPropertyHandler

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

addFormItem

public FormItem addFormItem(java.util.Locale locale,
                            User user,
                            java.lang.String usageIdentifyer,
                            boolean isAdministrativeUser,
                            FormItemContainer formItemContainer)

Description copied from interface: UserPropertyHandler

Adds a flexi-form Item for this UserPropertyHandler. The usageIdentifyer indicates in which form the element is to be used.

Specified by:

addFormItem in interface UserPropertyHandler

Overrides:

addFormItem in class Generic127CharTextPropertyHandler

Parameters:

locale - The current users locale

user - The user containing data to be prefilled or NULL if it should be left empty

usageIdentifyer - The identifyer of the form where this form element is used

isAdministrativeUser - true: Form element will be set to administrative mode. false: the element is set to user mode. In some cases the field is then read-only

formItemContainer - Container to which Form Item has to be added

Returns:

The formItem will be added to formItemContainer

Generic127CharTextPropertyHandler.addFormItem(java.util.Locale, org.olat.core.id.User, java.lang.String, boolean, org.olat.core.gui.components.form.flexible.FormItemContainer)

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.

Specified by:

isValid in interface UserPropertyHandler

Overrides:

isValid in class Generic127CharTextPropertyHandler

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)
