Class ScriptTokenParser

java.lang.Object
org.jmol.script.ScriptTokenParser
Direct Known Subclasses:
ScriptCompiler
abstract class ScriptTokenParser extends Object
An abstract class subclassed by ScriptCompiler taking care of the second phase of syntax checking. After all the tokens are created, these methods ensure that they are in the proper order in terms of expressions, primarily. Here we are going from an "infix" to a "postfix" set of tokens and then back to infix for final storage.
