Interface IXItemFieldNameConventions

  • All Known Implementing Classes:
    DefaultXItemFieldNameConventions, EBuiltinFieldNameConventions
    public interface IXItemFieldNameConventions
    Describes the naming conventions for the form fields used by this type of form item. The default assumption is that in the rendered form, only a single form field (such as <input>) exists, with the name as configured in the form designer. The default implementation returns DefaultXItemFieldNameConventions, which is suitable for such form items.

    Some form items may have more complex naming conventions. For example, an upload form item could have a secondary input field for storing the UUID of the upload; and the name of that derived input field could e.g. be the configured name (e.g. upl1) plus some suffix (e.g. upl1.uuid). Other form could have more derived field names with various data, as is the case for e.g. the builtin appointment picker form item with various related field names such app1_date, app1_time, app1_date_time, or app1.typeuuid etc.

    Implementations of this interface contain the field name conventions for such items, so that these conventions can be respected and enforced by formcycle. formcycle must be aware of the naming conventions for various reason, e.g. in order to be able to reject submitted request values when the request value belongs to a form item that is unavailable in a certain state or for certain user groups.

    • Method Detail

      • findRelatedBaseNames

        Set<String> findRelatedBaseNames​(String baseName)
        Given the base name of a form item, returns the set of additional related names that might be submitted.

        For example, when the form contains an autocomplete element with the name sel1, the form submission might include a value for the related name sel1_autocomplete in addition to the value for the name sel1. This method should then return a set with the one value sel1_autocomplete when called with the base name sel1.

        This is the inverse operation of resolveRelatedBaseName. If this method is given a string X and returns a set of strings Y, then resolveRelatedBaseName must return X if given any of the strings Y.

        This method is never given a derived name for repeated form fields. Repeated form fields use the convention tf1_dyn_fs1_0 (item base name tf1, container base name fs1, repetition ID 0).

        Parameters:
        baseName - The base name of an item.
        Returns:
        A set of related base names. null or the empty set when there are no related base name.

      • resolveRelatedBaseName

        String resolveRelatedBaseName​(String relatedBaseName)
        Given the base name of a request value, finds the base name of the form item that produced this request value.

        For example, when the form contains an autocomplete element with the name sel1, the form submission might include a value for the related name sel1_autocomplete in addition to the value for the name sel1. This method should then return sel1 when given the name sel1_autocomplete.

        This method is never given a derived name for repeated form fields. Repeated form fields use the convention tf1_dyn_fs1_0 (item base name tf1, container base name fs1, repetition ID 0).

        This is the inverse operation of findRelatedBaseNames. If findRelatedBaseNames is given a string X and returns a set of strings Y , then this method must return . X if given any of the strings Y.

        Parameters:
        relatedBaseName - A related base name to resolve.
        Returns:
        The resolved base name. null, the empty string, or the argument itself when the name is unknown to this conventions instance.
