      • convert

        public java.util.Collection<T> convert​(java.lang.Object value)
        Description copied from interface: TypeConverter
        Converts object received as parameter into object of another class. For example, an Integer converter tries to convert given objects into target Integer object. Converters should try all reasonable ways of conversion into target object, depending on target type.
        Specified by:
        convert in interface TypeConverter<T>
        Parameters:
        value - object to convert from
        Returns:
        resulting object converted to target type

      • convertType

        protected T convertType​(java.lang.Object value)
        Converts type using type converter manager.

      • createCollection

        protected java.util.Collection<T> createCollection​(int length)
        Creates new collection of target component type. Default implementation uses reflection to create an collection of target type. Override it for better performances.

      • convertToSingleElementCollection

        protected java.util.Collection<T> convertToSingleElementCollection​(java.lang.Object value)
        Creates a collection with single element.

      • convertValueToCollection

        protected java.util.Collection<T> convertValueToCollection​(java.lang.Object value)
        Converts non-collection value to collection.

      • convertCollectionToCollection

        protected java.util.Collection<T> convertCollectionToCollection​(java.util.Collection value)
        Converts collection value to target collection. Each element is converted to target component type.

      • convertPrimitiveArrayToCollection

        protected java.util.Collection<T> convertPrimitiveArrayToCollection​(java.lang.Object value,
                                                                    java.lang.Class primitiveComponentType)
        Converts primitive array to target collection.
