Small Footprint</h1></center>
|
|
A few changes can be made to reduce the footprint of Rhino for embeddings
|
|
where space is at a premium. On a recent build, Rhino consumed 355,883
|
|
bytes of space for uncompressed class files. With various changes that
|
|
number can be reduced to 281,455 bytes.
|
|

|
<h3>
|
|
Tools</h3>
|
|
Most embeddings won't need any of the classes in <tt>org.mozilla.javascript.tools</tt>
|
|
or any of its subpackages.
|
|
<br>
|
|
<h3>
|
|
Regular Expressions</h3>
|
|
The package <tt>org.mozilla.javascript.regexp</tt> can be removed. Rhino
|
|
will continue to run, although it will not be able to execute any regular
|
|
expression matches. This change saves 37,792 bytes of class files.
|
|
<br>
|
|
<h3>
|
|
JavaAdapter</h3>
|
|
Implementing the JavaAdapter functionality requires the ability to generate
|
|
classes on the fly. Removing <tt>org.mozilla.javascript.JavaAdapter</tt> and all
|
|
the classes in package <tt>org.mozilla.classfile</tt> will disable this
|
|
functionality, but Rhino will otherwise run correctly. These changes save
|
|
36,636 bytes.
|
|
<br>
|
|
<h3>
|
|
Optimizer</h3>
|
|
It is possible to run Rhino with interpreter mode only, allowing you to remove
|
|
classes for classfile generation. Remove the classes in packages
|
|
<tt>org.mozilla.classfile</tt> and <tt>org.mozilla.javascript.optimizer</tt>.
