1.51 CType

Defined in namespace Smalltalk

Superclass: Object

Category: Language-C interface

I am not part of the standard Smalltalk kernel class hierarchy. I contain type information used by subclasses of CObject, which represents external C data items.

My only instance variable, cObjectType, is used to hold onto the CObject subclass that gets created for a given CType. Used primarily in the C part of the interpreter because internally it cannot execute methods to get values, so it has a simple way to access instance variable which holds the desired subclass.

My subclasses have instances which represent the actual data types; for the scalar types, there is only one instance created of each, but for the aggregate types, there is at least one instance per base type and/or number of elements.

• CType class-C instance creation: (class)
• CType class-initialization: (class)
• CType-accessing: (instance)
• CType-C instance creation: (instance)
• CType-storing: (instance)
