extractback to summary
pack-priv static boolean extract(String extractToFilePath, String mappedName)

Extract file with 'mappedName' into path 'extractToFilePath'. Does not overwrite existing file. Does not leave trash on error.

Parameters
extractToFilePath:String

full path of where the file is to be extacted to, inc name of file, e.g /home/USER/.swt/lib/linux/x86_64/libswt-MYLIB-gtk-4826.so

JAVA_VERSIONback to summary
public static int JAVA_VERSION(int major, int minor, int micro)

Returns the Java version number as an integer.

Returns:int

loadback to summary
pack-priv static boolean load(String libName, StringBuilder message)
loadLibraryback to summary
public static void loadLibrary(String name)

Loads the shared library that matches the version of the Java code which is currently running. SWT shared libraries follow an encoding scheme where the major, minor and revision numbers are embedded in the library name and this along with name is used to load the library. If this fails, name is used in another attempt to load the library, this time ignoring the SWT version encoding scheme.

Parameters
name:String

the name of the library to load

loadLibraryback to summary
public static void loadLibrary(String name, boolean mapName)

Loads the shared library that matches the version of the Java code which is currently running. SWT shared libraries follow an encoding scheme where the major, minor and revision numbers are embedded in the library name and this along with name is used to load the library. If this fails, name is used in another attempt to load the library, this time ignoring the SWT version encoding scheme.

Parameters
name:String

the name of the library to load

mapName:boolean

true if the name should be mapped, false otherwise
