  • Method Details

    • getScope

      public Scope getScope()

    • getOperandStack

      @Nonnull public Stack<AST> getOperandStack()

    • getExecutionContext

    • compile

      public ValueType compile(@Nonnull String expression, Scope compileScope, boolean fullResolve)
      Compile a JavaScript style expression string to an instruction list.
      Parameters:
      expression - String to compile
      compileScope - The symbol table to use
      fullResolve - If true symbol lookups are resolved directly with suppliers from the scope else lookup instructions are created
      Returns:
      The return type of the expression (instruction can be read with getInstructions())

    • compile

      public ValueType compile(@Nonnull String expression, Scope compileScope, boolean fullResolve, List<ExecutionContext.Instruction> instructions)
      Compile a JavaScript style expression string to an instruction list.
      Parameters:
      expression - String to compile
      compileScope - The symbol table to use
      fullResolve - If true symbol lookups are resolved directly with suppliers from the scope else lookup instructions are created
      instructions - list to store instructions too (will be cleared)
      Returns:
      The return type of the expression (instruction can be read with getInstructions())
