Class CommSpaceElement

java.lang.Object

  +--edu.utah.janosvm.kit.comm.commspace.CommSpaceElement

All Implemented Interfaces:

java.lang.Cloneable

public final class CommSpaceElement

extends java.lang.Object

implements java.lang.Cloneable

Element in the CommSpace for communication. This is what gets written to the CommSpace

XXX does this need to exist or can I just stick Objects in the CommSpace?

XXX because the val field is final, its impossible to re-use a CommSpaceElement (i.e., for a different object...) Could work around this by making the val field read-only while the object was lodged in the CommSpace...

XXX these are shared between processes.... i.e., they leak (~2 words).

"Big Deal." -- Chris H.

XXX Should the get methods be copying their contents?
