public class VMObjectClass
extends ObjectClass
implements IVMClass

The VMObjectClass is an ObjectClass with extensions for use in the Brahms virtual machine. The concept of a class' in Brahms is similar to the concept of a template or class in object-oriented programming. It defines the activities (workframes), initial-facts and initial-beliefs for instances of that class (i.e. 'objects'). Classes are used to define inanimate artifacts, such as phones, faxes, computer systems, pieces of paper, etc.

Constructor Detail

VMObjectClass

public VMObjectClass()

Constructor, creates a new group for use in the virtual machine.

VMObjectClass

public VMObjectClass(java.lang.String name)

Constructor, creates a new class with the specified name for use in the virtual machine.

Parameters:

name - the unique name of the class

VMObjectClass

public VMObjectClass(java.lang.String file,
                     int line)

Constructor, creates a new class for use in the virtual machine.

Parameters:

file - the name of the file in which the class is specified

line - the line number at which the definition of the class starts

VMObjectClass

public VMObjectClass(java.lang.String name,
                     java.lang.String file,
                     int line)

Constructor, creates a new class with the specified name for use in the virtual machine.

Parameters:

name - the unique name of the class

file - the name of the file in which the class is specified

line - the line number at which the definition of the class starts

Method Detail

createInstance

public IVMInstance createInstance(java.lang.String name)

Creates a new object instance with this object class as its parent.

Specified by:

createInstance in interface IVMClass

Parameters:

name - the unique name in the runtime model for the instance.

Returns:

IVMInstance a new ObjectInstance

equals

public boolean equals(java.lang.Object obj)

Tests whether two VMObjectClasses are equal. The VM maintains a single instance of any VMObjectClass with a given FQN in its static model, so the equality check can be reduced to an identity check

Overrides:

equals in class Concept

Parameters:

obj - the Object to be compared for equality

Returns:

true if the two VMObjectClasses are equal, false otherwise
