protected ExecutableArchiveLauncher(Archive archive)

方法详细资料

getClassPathIndex

protected org.noear.solon.loader.ClassPathIndexFile getClassPathIndex(Archive archive)
                                                               throws IOException

抛出:

IOException

getMainClass

protected String getMainClass()
                       throws Exception

从类复制的说明: Launcher

Returns the main class that should be launched.

指定者:

getMainClass 在类中 Launcher

返回:

the name of the main class

抛出:

Exception - if the main class cannot be obtained

createClassLoader

protected ClassLoader createClassLoader(Iterator<Archive> archives)
                                 throws Exception

从类复制的说明: Launcher

Create a classloader for the specified archives.

覆盖:

createClassLoader 在类中 Launcher

参数:

archives - the archives

返回:

the classloader

抛出:

Exception - if the classloader cannot be created

getClassPathArchivesIterator

protected Iterator<Archive> getClassPathArchivesIterator()
                                                  throws Exception

从类复制的说明: Launcher

Returns the archives that will be used to construct the class path.

指定者:

getClassPathArchivesIterator 在类中 Launcher

返回:

the class path archives

抛出:

Exception - if the class path archives cannot be obtained

isSearchCandidate

protected boolean isSearchCandidate(Archive.Entry entry)

Determine if the specified entry is a candidate for further searching.

参数:

entry - the entry to check

返回:

true if the entry is a candidate for further searching

从以下版本开始:

2.3.0

isNestedArchive

protected abstract boolean isNestedArchive(Archive.Entry entry)

Determine if the specified entry is a nested item that should be added to the classpath.

参数:

entry - the entry to check

返回:

true if the entry is a nested item (jar or directory)

isPostProcessingClassPathArchives

protected boolean isPostProcessingClassPathArchives()

Return if post processing needs to be applied to the archives. For back compatibility this method returns true, but subclasses that don't override postProcessClassPathArchives(List) should provide an implementation that returns false.

返回:

if the postProcessClassPathArchives(List) method is implemented

从以下版本开始:

2.3.0

postProcessClassPathArchives

protected void postProcessClassPathArchives(List<Archive> archives)
                                     throws Exception

Called to post-process archive entries before they are used. Implementations can add and remove entries.

参数:

archives - the archives

抛出:

Exception - if the post processing fails

getArchiveEntryPathPrefix

protected String getArchiveEntryPathPrefix()

Return the path prefix for entries in the archive.

返回:

the path prefix

isExploded

protected boolean isExploded()

从类复制的说明: Launcher

Returns if the launcher is running in an exploded mode. If this method returns true then only regular JARs are supported and the additional URL and ClassLoader support infrastructure can be optimized.

覆盖:

isExploded 在类中 Launcher

返回:

if the jar is exploded.

getArchive

protected final Archive getArchive()

从类复制的说明: Launcher

Return the root archive.

覆盖:

getArchive 在类中 Launcher
