de.ipcon.db.core.AttributeSelector

public class AttributeSelector
extends java.lang.Object

Support class that bundles common code needed for attribute selection input fields in the GUI. The selected attribute will be available as a String, the attribute name. The class that wishes to store some attribute (name) must provide three attributes (and the required getters and setters) itself: - a virtual writable single relation of type BX - a virtual (readonly) many relation of type BX - a persistent attribute to store the selected attribute name in with overwritten setter For an example see de.ipcon.db.core.Wiedervorlage with its attributes "AttributBX", "VerfuegbareAttribute" and "AttributFuerInaktivitaetMessenAb" which persistently stores the actual attribute name. The GUI code used for that is:

Method Detail

setAttribut

public java.lang.String setAttribut(java.lang.String attributeName)

Sets the internal BX to null and returns _attr unchanged. Supposed to be called from the setter of the actual attribut which stores the selected attribute's name.

getAttributBX

public BX getAttributBX(java.lang.String attributeName,
                        BOT bot,
                        BOLoaderI bol)

getAttributBX

public BX getAttributBX(java.lang.String attributeName,
                        BOT bot,
                        BOLoaderI bol,
                        java.util.List<AttributeI> listOfAllAttrs)

getAttributBX

public BX getAttributBX(java.lang.String attributeName,
                        BOMaske mask,
                        BOLoaderI bol)

Returns a matching BX with VString set to the selection entry string for the corresponding attribute
