public class VariableAssembler

extends Assembler

This class looks up a variable by name, using the word on an assembly's stack, and pushes a Variable of that name.

This class expects an assembly's target to be a SlingPlot object. The target has a "scope", which is a collection of variables organized by name. When this assembler works on an assembly, it pops a name from the stack, looks up a variable in the scope using the name, and pushes the variable onto the stack. This lookup creates the variable in the scope if the scope does not already contain a variable of that name.
