INFO FOR PEOPLE ADDING CHANGES:

Check the DTD (apichanges.dtd) for details on the syntax. You do not

need to regenerate the HTML, as this is part of Javadoc generation; just

change the XML. Rough syntax of a change (several parts optional):

<change>

    <api name="compiler"/>

    <summary>Some brief description here, can use <b>XHTML</b></summary>

    <version major="1" minor="99"/>

    <date day="13" month="6" year="2001"/>

    <author login="jrhacker"/>

    <compatibility addition="yes"/>

    <description>

        The main description of the change here.

        Again can use full <b>XHTML</b> as needed.

    </description>

    <class package="org.openide.compiler" name="DoWhatIWantCompiler"/>

    <issue number="14309"/>

</change>

Also permitted elements: <package>, <branch>. <version> is API spec

version, recommended for all new changes. <compatibility> should say

if things were added/modified/deprecated/etc. and give all information

related to upgrading old code. List affected top-level classes and

link to issue numbers if applicable. See the DTD for more details.

Changes need not be in any particular order, they are sorted in various

ways by the stylesheet anyway.

Dates are assumed to mean "on the trunk". If you *also* make the same

change on a stabilization branch, use the <branch> tag to indicate this

and explain why the change was made on a branch in the <description>.

Please only change this file on the trunk! Rather: you can change it

on branches if you want, but these changes will be ignored; only the

trunk version of this file is important.

Deprecations do not count as incompatible, assuming that code using the

deprecated calls continues to see their documented behavior. But do

specify deprecation="yes" in <compatibility>.

This file is not a replacement for Javadoc: it is intended to list changes,

not describe the complete current behavior, for which ordinary documentation

is the proper place.

 <answer id="arch-what">

  <p>

   The Base Input/Output APIs is a small API module

   which contains <code>InputOutputBase</code> and related interfaces used in

   driving the Output Window. The normal implementation is

   <code>org.netbeans.core.output2</code>.

  </p>

  <p>

   The API was extracted from module openide.io, which depends on some

   GUI-related classes. This module has no such dependencies.

            <hint>

                Most of algorithms have increasing memory and speed complexity

                with respect to size of data they operate on. What is the critical

                part of your project that can be seen as a bottleneck with

                respect to speed or required memory? What are the practical

                sizes of data you tested your project with? What is your estimate

                of potential size of data that would cause visible performance

                problems? Is there some kind of check to detect such situation

                and prevent "hard" crashes - for example the CloneableEditorSupport

                checks for size of a file to be opened in editor

                and if it is larger than 1Mb it shows a dialog giving the

                user the right to decide - e.g. to cancel or commit suicide.

            <hint>

                If you do a lot of tricks when adding actions to regular or context menus, you can significantly

                slow down display of the menu, even when the user is not using your action. Pay attention to

                actions you add to the main menu bar, and to context menus of foreign nodes or components. If

                the action is conditionally enabled, or changes its display dynamically, you need to check the

                impact on performance. In some cases it may be more appropriate to make a simple action that is

                always enabled but does more detailed checks in a dialog if it is actually run.
