Constructor Summary

FluidVar(BlockClosure initialBlock, Emulsion emulsion, Symbol name, java.lang.Class classx)
This create the first fluid variable within the emulsion

Method Summary

static void	cleanup(Symbol varName) If there is a fluidVar by the given name, set its value to nil
static void	cleanupGarbage() Reset all fluid variables to their initial states.
void	emulsion()
void	fluidBindDuring(java.lang.Object value, java.lang.Object dynamicBlock) Take on new definition during execution of a block, and assure that old value is restored. For the benefit of smalltalk only code that may want to use this in an expression, the result of the block evaluation is returned.
void	fluidFetch() Return the fluidly bound value.
void	fluidGet() Return the fluidly bound value.
void	fluidSet(java.lang.Object newValue) self == CurrentPacker ifTrue: [self halt].
void	fluidVar() Return the fluidly bound value.
