Abstract

A component based software program, where each component is based on a component-type. Component-types are created from base classes comprising slot definitions. The slot definitions are identified and stored in a component-type object. One or more components of the component-type are created, each comprising a reference, to a component-type object and a slotmap having storage locations for values associated with property slots definitions, in the component-type object. Values for property slots are entered into components by being placed in the storage locations. Also disclosed is a method for automatically designating unique names to components. One root component is created. Further non-root components are placed within the root component or within other components, so that all components form a tree structure. A component is assigned a unique identification string, comprising a sequential list of all of the component's ancestors and the component's name.

Dependent claims

A software program for execution on a machine, the software program including one or more components of the same component-type, the component type being defined from a base class comprising one or more slot definitions at least one of which is a property slot definition, the components being generated during run-time by the steps comprising:

identifying all property slot definitions in the base class;
locating getter and setter methods for each identified property slot definition in the base class;
generating a component-type object, the component-type object being configured to store slot definitions;
storing in the component-type object the property slot definitions identified in the identifying step;
generating one or more components, each component having a slotmap and a reference to the component-type object, wherein each slotmap includes a storage location for the value of each property-slot definition stored in the component-type object;
and
setting a property slot value, by inserting the property slot value into a storage location in the slotmap of a particular one of the one or more components, the property slot value being associated with one of the property slot definitions in the component-type object.
