Interface Scope

All Known Implementing Classes:
StdLib, StdScope
public interface Scope
Scope representing a table of functions and variables to be used with expressions.

Symbols are typed and resolved to Suppliers to be able to skip name lookup after compilation. Also symbols can be constants to support constant folding while compiling.

    • isConstant

      boolean isConstant(String name)

      Parameters:
      name - Name of function/variable.
      Returns:
      true if variable is constant or function is invariant
