Method Detail

arch

static java.lang.String arch()

os

static java.lang.String os()

chmod

static void chmod(java.lang.String permision,
         java.lang.String path)

longConst

static long longConst()

parseVersion

static int parseVersion(java.lang.String version)

JAVA_VERSION

public static int JAVA_VERSION(int major,
               int minor,
               int micro)

Returns the Java version number as an integer.

Parameters:

major -

minor -

micro -

Returns:

the version

SWT_VERSION

public static int SWT_VERSION(int major,
              int minor)

Returns the SWT version number as an integer.

Parameters:

major -

minor -

Returns:

the version

extract

static boolean extract(java.lang.String fileName,
              java.lang.String mappedName,
              java.lang.StringBuffer message)

isLoadable

static boolean isLoadable()

load

static boolean load(java.lang.String libName,
           java.lang.StringBuffer message)

loadLibrary

public static void loadLibrary(java.lang.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 - the name of the library to load

loadLibrary

public static void loadLibrary(java.lang.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 - the name of the library to load

mapName - true if the name should be mapped, false otherwise

mapLibraryName

static java.lang.String mapLibraryName(java.lang.String libName)
