类 PrepareLibs

java.lang.Object

net.sunyijun.resource.library.PrepareLibs

public class PrepareLibs
extends Object

Methods to prepare(copy or load) libraries.

If library file will change, must use initialLibFiles(java.lang.String...) method before loadLibFiles(java.lang.String, java.lang.String...). If won't changed at all, just loadLibFiles(java.lang.String, java.lang.String...). This may call System.loadLibrary()
If library file is dll or so files, can use loadDllFiles(java.lang.String...) or loadSoFiles(java.lang.String...) instead of loadLibFiles(java.lang.String, java.lang.String...).

initialLibFiles

public static void initialLibFiles(String... libAbsoluteClassPaths)
                            throws IOException

Initial library resources: copy resources from class path to library path either library file exists or not exists in library path.

Use this method can use newest library file.

参数:

libAbsoluteClassPaths - library absolute class path(start with"/"), include file name.

抛出:

IOException

loadDllFiles

public static String[] loadDllFiles(String... dllAbsoluteClassPaths)

Load dll libraries which placed in class path.

参数:

dllAbsoluteClassPaths - dll library absolute class path(start with"/"), include file name.

返回:

dll library class paths that failed to load. If all success, return array size is 0.

loadSoFiles

public static String[] loadSoFiles(String... dllAbsoluteClassPaths)

Load so libraries which placed in class path.

参数:

dllAbsoluteClassPaths - so library absolute class path(start with"/"), include file name.

返回:

so library class paths that failed to load. If all success, return array size is 0.

loadLibFiles

public static String[] loadLibFiles(String fileSuffix,
                                    String... libAbsoluteClassPaths)

Load libraries which placed in class path.

参数:

fileSuffix - suffix include".". eg:".dll"

libAbsoluteClassPaths - library absolute class path(start with"/"), include file name.

返回:

library class paths that failed to load. If all success, return array size is 0.

prepareLibFiles

public static void prepareLibFiles(String... libAbsoluteClassPaths)
                            throws IOException

Prepare library resources: copy resources from class path to library path when library file not exists in library path.

Use this method can avoid copy same lib more than once. But if lib changed, it will not work till use initialLibFiles(java.lang.String...).

参数:

libAbsoluteClassPaths - library absolute class path(start with"/"), include file name.

抛出:

IOException
