Interface TypeUtils

All Known Implementing Classes:

StandardTypeUtilities

public interface TypeUtils

TypeUtilities brings together the various kinds of type related function that may occur whilst working with expressions. An implementor is providing support for four type related facilities:

• a mechanism for finding types
• a mechanism for comparing types
• a mechanism for type conversion/coercion
• a mechanism for overloading mathematical operations (add/subtract/etc)
