<pre>public abstract class <span class="typeNameLabel">CompiledExpression</span>
extends java.lang.Object</pre>
<div class="block">This abstract class is a superclass of every JEL-compiled expression,
each of which overrides some of the abstract methods below.
<p> Most methods of this class accept a reference to the array of objects.
This reference is a pointer to the dynamic object library. As you know,
JEL allows to call virtual methods of Java classes, but, as you also know,
virtual methods require a reference to an object instance
(<tt>this</tt>) to be
passed along with parameters. The array <tt>dl</tt> (dynamic
library) serves just this purpose. It should contain references
to objects of all classes, whose
<i>virtual</i> methods were put into the Library of callable functions.
Objects
in the <tt>dl</tt> array should correspond one-to-one to classes
in the array, passed as a second argument of <TT>gnu.jel.Library</TT>
constructor.
<p>
<p> There are two ways of evaluating the compiled expressions allowing
to compromise between raw performance and simplicity:
<p> The <i>first method</i> (simplest one) is based on the call to the
<TT> evaluate</TT> method, which will
return an object even if the result of computation was of a primitive type.
The primitive types will be automatically converted into the
corresponding reflection
objects. There is certain overhead, associated with object creation, it
takes CPU cycles and also produces load on the garbage collector later..
<P>For massive (thousand times) evaluations of functions, producing
results of primitive Java types, the <I>second
method</I> can be more suitable. It is based on : first, determining the
type of the result, and, then, subsequent call to the
<U>corresponding</U> evaluateXXX method.
<P> The type of the resulting expression can be determined by call to the
getType() method. It will return an integer number, indentifying the type,
<U>proper</U> evaluateXXX method can be determined,
based on the following table:
<PRE>
getType() | method to call
------------+----------------------
0 | evaluate_boolean(...)
1 | evaluate_byte(...)
2 | evaluate_char(...)
3 | evaluate_short(...)
4 | evaluate_int(...)
5 | evaluate_long(...)
6 | evaluate_float(...)
7 | evaluate_double(...)
8 | evaluate(...) <- result is Object (universal method)
9 | evaluate_void(...)
-----------------------------------
</PRE>
<P> Note: If a wrong evaluateXXX() method is called, it will return zero,
and, in debug version of JEL (jel_g.jar) only, a warning will be
printed to stderr.
<P> There is a possibility to enforce resulting type of the expression at
compile time (see <tt>gnu.jel.Evaluator</tt>).
Use it to avoid unnecesary type checks.</div>

their meaning. Also, this shoul never be necessary because these

<div class="block">Returns the type of the expression result.
<p>If the result has primitive type the corresponding wrapper
class is returned (please note that it is just a wrapper class like
java.lang.Integer instead of exact primitive type class
java.lang.Integer.TYPE). This corresponds to the wrapping done
in non-specialized evaluate() method.
<p>When the result is an object, the returned value is the most
specific reference to the class of that object (which is always
a subclass of the returned class) available at compile time.
<p>The precision of determining the result type this way mainly
depends on the design of the user's function namespace (defined
by gnu.jel.Library class). It is possible to design a library in
such a way that the best approximation to the result type obtainable
at compile time would be the java.lang.Object class, which will
be returned by this method, thus, providing no useful information
about the actual type.
<p>Please note again that the guaranteed exact type of the result can't be
determined at compile time and can be quiered only after evaluating
the expression (directly from resulting object).
<p> The only guarantee
this method provides is that a variable of the returned expression type
can be assigned by a reference, resulting from a call to evaluate.</div>
