Exported Interfaces

This table lists all of the module exported APIs with defined stability classifications. It is generated based on answers to questions about the architecture of the module. Read them all...

Group of java interfaces

Interface Name	In/Out	Stability	Specified in What Document?
ExceptionAnnotatableUsingLogRecords	Exported	Friend	To support classification of exceptions and also annotation of exceptions with logging levels and additional localized messages, logged exceptions and their initCause's are searched for implementation of Callable<LogRecord[]>. If an exception implements this interface, the call() method is called and returned LogRecords then scanned for messages, levels, etc.

Group of java.io.File interfaces

Interface Name	In/Out	Stability	Specified in What Document?
nbexec	Exported	Stable	...//platform.netbeans.org/articles/installation.html
lock-file	Exported	Private	The lock file ${netbeans.user}/lock will have file permissions changed to go-rwx for safety on Unix systems (requires presence of chmod)
nbexec.exe	Exported	Stable	...//platform.netbeans.org/articles/installation.html
ClassPath-Composition	Exported	Private	Bootstrap code creates a class loader to load the rest of the core from. The bootstrap code is loaded from the Java application class loader, using the classpath lib/*.jar.
Dynamic-ClassPath-Composition	Exported	Friend	After creating bootstrap classpath another low level set of JARs is loaded with a new classloader from core/*.jar directories in each clusters.
imported-marker	Exported	Friend	${netbeans.user}/var/imported is used to identify whether a userdir has already been updated or it still needs an update. Can be created by installer if no update check should be performed, no other code is supposed to realy on this file.
license-check-marker-file	Exported	Friend	${netbeans.user}/var/license_accepted and ${nbcluster.dir}/var/license_accepted are used to identify whether user accepted license.
.lastModified	Exported	Under Development	To speedup testing that module caches are up-to-date, the system recognizes special file inside of each cluster. If .lastModified file is present in a cluster, then the content of the cluster is not scanned any more deeply and instead the time stamp of the file is used as last modification for the whole content of the cluster. This API is primarily intended for use by installer and RPM packagers and also autoupdate, that are supposed to create such file, as soon as they finish modifications to any cluster. This file is ignored when accessing user directory, as it is expected that user can modify it, while the user usually does not have access permision or need to modify the shared installation clusters.
cached.lastModified	Exported	Private	If the .lastModified file is not present in cluster directory, it is recomputed on startup and stored in $userdir/var/cache/lastModified/$clustername. This file and its content is meant just for private consumption of the IDE.
all-resources.dat	Exported	Under Development	To speedup class loading during startup, the system keeps a cache of resources needed during startup in var/cache/all-resources.dat. If the cache is valid, it is loaded during startup and class and resource loading requests are redirected there. The file is binary and shouldn't be modified by other code than org.netbeans.Archive. The file content uses magic header and versioning to allow evolution of its (private) format.

Group of property interfaces

Interface Name	In/Out	Stability	Specified in What Document?
java.util.logging.Level.1973	Exported	Deprecated	LogRecords sent to registered logger may be marked as those intended for user. This can be done by logging with level which has intValue() == 1973. Localized message of such log records is then shown in a special dialog. This behaviour is supported for backward compatibility, but in fact it is deprecated. The preferred way is to directly show dialog using DialogDisplayer.
netbeans.exception.alert.min.level	Exported	Under Development	Minimum integer level that triggers the blinking icon signaling an exceptional state. By default 900 - e.g. WARNING.
netbeans.exception.report.min.level	Exported	Under Development	Minimum integer level that triggers the dialog with exception. By default 900 with assertions on and 1001 without them.
netbeans.mainclass	Exported	Friend	Main Java class for bootstrap code to start (currently org.netbeans.core.startup.Main). Might be used by alternate launchers.
NetBeans-IDE-Dev	Exported	Private	The registry key Software\netbeans.org\NetBeans IDE\Dev Default user directory, unless --userdir is given. The name of this registry key is brandable, as is its default value. [Windows only]
netbeans.home	Exported	Under Development	NetBeans installation directory (where the launcher is).
netbeans.user	Exported	Under Development	NetBeans user directory.
netbeans.dirs	Exported	Friend	Additional secondary NetBeans installation directories, if applicable.
netbeans.system_http_proxy	Exported	Under Development	System proxy setting in the format of hostname:port. The launcher does its best to detect the OS/desktop HTTP proxy setting. There is no guarantee that it succeeds. The property may not be set at all or its value may be totally wrong.
netbeans.system_http_non_proxy_hosts	Exported	Under Development	List of addresses that are not accessed through proxy. The launcher attempts to detect the OS/desktop HTTP proxy setting. There is no guarantee that it succeeds. The property may not be set at all or its value may be totally wrong and its format is not defined.
netbeans.classpath	Exported	Friend	Classpath to prepend to core loader (normally just lib/*.jar). Possibly useful for testing infrastructure etc.
netbeans.importclass	Exported	Friend	There is a special support for importing the settings from previous versions. As only the product itself knows about what to import and where this cannot be done directly in the launcher, but we need at a well defined moment (user directory is missing and no modules have been initialized yet) to call the product to ask the user and do the actual copy of userdir. After all core/*.jar files has been initialized and the user dir has not yet been updated (see bellow) the launcher checks for value of netbeans.importclass system property and if provided it loads that class and invokes its main method (in AWT thread) and if no exception is thrown it marks the userdir as already upgraded.
netbeans.accept_license_class	Exported	Friend	Before first usage of IDE user must accept license. If user does not install IDE by installer (user must accept license during installation) user must accept license during IDE first start. Launcher calls method showLicensePanel of netbeans.acceptlicenseclass if license was not yet accepted by user and it is necessary to show license in dialog to user.
netbeans.logger.console	Exported	Friend	Controls whether to log messages to the console, or just to the log file.
org.netbeans.CLIHandler	Exported	Private	Setting this property to less than zero value enables logging of what is going on in the CLIHandler - e.g. in the code that locks user directory and handles processing of command line options. Use -J-Dorg.netbeans.CLIHandler=-1 to send the logging to System.err.
org.netbeans.core.systemfilesystem.custom	Exported	Friend	Contains class name of a class that can serve as provider of the writable layer of the system file system. The class must be a subclass of org.openide.filesystems.FileSystem and have public default constructor. Morevoer the class denoted by the property must be on the classpath.
SplashOnByDefault	Exported	Under Development	can be true or false, allows some applications build on top of the platform to disable splash by default

Group of logger interfaces

Interface Name	In/Out	Stability	Specified in What Document?
org.netbeans.ProxyClassLoader	Exported	Private	This logger logs at WARNING level about accessing resources from the default package.

Group of cli interfaces

Interface Name	In/Out	Stability	Specified in What Document?
--jdkhome	Exported	Under Development	JDK (or perhaps JRE) installation directory.
--clusters	Exported	Under Development	The list of clusters to intialize the system from. Is used to set the value of netbeans.dirs.
--userdir	Exported	Under Development	User directory, if not the default.
-JWHATEVER	Exported	Under Development	Pass option WHATEVER to the JVM.
--cp	Exported	Under Development	-cp:a and -cp:p append and prepend to the startup classpath; deprecated except for special purposes such as installing a custom look & feel.
--ui	Exported	Under Development	Specify a look & feel. The same as --laf. To make human life easier simple translation was added to convert L&F ID to L&F class name for known L&Fs. Metal is translated to javax.swing.plaf.metal.MetalLookAndFeel GTK is translated to com.sun.java.swing.plaf.gtk.GTKLookAndFeel Nimbus is translated to com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel Windows is translated to com.sun.java.swing.plaf.windows.WindowsLookAndFeel Aqua is translated to apple.laf.AquaLookAndFeel
--laf	Exported	Under Development	Specify a look & feel. The same as --ui.
--bootclass	Exported	Under Development	Alternative main class used to initialize the system.
--fontsize	Exported	Deprecated	Specify base fontsize. Deprecated in favor of using themes which is much more general. But this is a convenient quick settings, handy for projection screens and so on.
--locale	Exported	Under Development	Specify system locale.
--branding	Exported	Under Development	Specify application branding.
--nologging	Exported	Private	Do not write a log file.
--nosplash	Exported	Friend	Do not show the splash screen.
--nogui	Exported	Friend	Do not show any GUI at all.
--reload	Exported	Under Development	Reload a test module.

Group of lookup interfaces

Interface Name	In/Out	Stability	Specified in What Document?
lookup.org.netbeans.CLIHandler	Exported	Friend	Instances of org.netbeans.CLIHandler are found using services lookup in the "dynamic classpath loader" (i.e. startup classpath plus ${netbeans.home}/core/*.jar).
org.netbeans.ModuleFactory	Exported	Friend	Instances of org.netbeans.ModuleFactory are found using services lookup in the "dynamic classpath loader" (i.e. startup classpath plus ${netbeans.home}/core/*.jar). ModuleFactory can be used to create alternative module implementations.
CoreBridge	Exported	Private	The communication between core.jar and rest of the platform code in org-netbeans-core.jar is handled thru handled thru CoreBridge calls.
RunLevel	Exported	Friend	Additional callbacks from core.jar after the module system is started are done using RunLevel interface. Currently it starts window system.
java.util.logging.Handler	Exported	Friend	There is a communication bridge between the default logging handler registered by core/startup and the UI handler in core that presents certain log records in the UI.
