/**
This file implements an expression parser for Ptolemy II using the
JavaCC parser generator. It can handle all the basic arithmetic operators
(*, /, +, -, %, ^), relational operators (<, ≤, >, ≥, == !=), logical
operators(&&, ||, !), bitwise operators (&, |, #, ~)  and, using
reflection, all of the functionality available in the java.lang.Math
package.
<p>
By editing the ASTFunctionNode file it is also relatively
easy to allow references to other functions. This provides an easy mechanism
to extend the range to the parser e.g. have a tcl(...) function
that passes the string to a Tcl interpreter and returns the result.</p>?
<p>
Functional if is supported via the following syntax:</p>?
<pre>
        (boolean) ? (value1) : (value2)
</pre>
<p>
Extensibility is also supported by allowing method calls on the Tokens,
the syntax is </p>?
<pre>
        (value1).method(comma separated arguments)
</pre>
<p>
JavaCC by itself simply generates a file (and support files) that allow an
input to be parsed, it does not return a parse tree. For the purposes of
type checking we require a parse tree, and this is obtained using JJTree, a
preprocessor for JavaCC. </p>?
<p>
JJtree operates by annotating the grammar file to support the generation
of the parse tree. Thus the process is</p>?
<pre>
X.jjt --&gt; JJTREE --&gt; X.jj --&gt; JAVACC --&gt; X.java + support files
</pre>
<p>
The parser can also be passed a symbol table of ptolemy.data.expr.Variables
which the expression to be parsed can reference.</p>

<p>Anything between quotes(") or apostrophes(') is taken to be one string.
Strings are allowed to contain newlines or carriage returns.  In
addition, these characters, as well as other special characters, can
be escaped using the standard Java syntax (\n, \t, \077, etc.).</p>

<p>The expressions recognized follow as close as possible the syntax of Java.
In particular the operator precedences implemented here follow exactly
those in Java. Any type conversions that are performed are lossless. If
the user wants lossy conversions, explicit casts will be necessary.</p>

<p>
Complex number are specified by an i or j after the imaginary part
of the number. Long numbers are specified by an l or L after an
integer number.</p>

<p>
Users can register constants with the parser and also register classes
where functions that may be called are defined. For a more
thorough description of what the Parser is designed to do,
please consult the Ptolemy II design document.</p>

<p>
Note that the parsers created by JavaCC generally have quite a bit of
internal state.  On the other hand, the parse trees generated by this
parser are much smaller.  It is also fairly cheap to traverse a parse
tree in order to evaluate it.  Thus it is usually preferable to cache
parse trees and create a new parser when the cached parse tree becomes
invalid.</p>
