• parameterExpression

  private Object parameterExpression(int pt, int ptMax, String key, boolean ignoreComma, boolean asVector, int ptAtom, boolean isArrayItem, Map<String,SV> localVars, String localVar, boolean isSpecialAssignment) throws ScriptException

  This is the primary driver of the RPN (reverse Polish notation) expression processor. It handles all math outside of a "traditional" Jmol SELECT/RESTRICT context. [Object atomExpression() takes care of that, and also uses the RPN class.]

  Parameters:

  pt - token index in statement start of expression or negative for one expression only.

  ptMax - token index in statement end of expression

  key - variable name for debugging reference only -- null indicates return Boolean -- "" indicates return String

  ignoreComma -

  asVector - a flag passed on to RPN;

  ptAtom - this is a for() or select() function with a specific atom selected

  isArrayItem - we are storing A[x] = ... so we need to deliver "x" as well

  localVars - see below -- lists all nested for(x, {exp}, select(y, {ex},...)) variables

  localVar - x or y in above for(), select() examples

  isSpecialAssignment - x[n] = ....

  Returns:

  either a vector or a value, caller's choice.

  Throws:

  ScriptException - errors are thrown directly to the Eval error system.

  protected SV setVariable(int pt, int ptMax, String key, boolean isSet) throws ScriptException

  Parameters:

  pt - starting point in command token sequence

  ptMax - ending point in command token sequenec, possibly -1 for "all"

  key - the variable name to save the result in. This must be a standard user variable, either local or global

• setStatement

  protected boolean setStatement(T[] st0, int pt0) throws ScriptException

  provides support for @x and @{....} in statements. The compiler passes on these, because they must be integrated with the statement dynamically.

  Parameters:

  pt0 -

  Returns:

  a fixed token set -- with possible overrun of unused null tokens

  Throws:

  ScriptException
