mapLibraryName
WrapsSystem.mapLibraryName(java.lang.String)
. On OS X with JDK 6, the .jnilib file extension will be replaced with .dylib.- Parameters:
name
- the name of the library.- Returns:
- a platform-dependent native library name.
-
getLibraryPaths
public static String[] getLibraryPaths(String libname, String platform_lib_name, ClassLoader classloader) Locates the paths required by a library.- Parameters:
libname
- Local Library Name to search the classloader with ("openal").platform_lib_name
- The native library name ("libopenal.so")classloader
- The classloader to ask for library paths- Returns:
- Paths to located libraries, if any
-
getLibraryPaths
public static String[] getLibraryPaths(String libname, String[] platform_lib_names, ClassLoader classloader) Locates the paths required by a library.- Parameters:
libname
- Local Library Name to search the classloader with ("openal").platform_lib_names
- The list of possible library names ("libopenal.so")classloader
- The classloader to ask for library paths- Returns:
- Paths to located libraries, if any
-

-
isMacOSXEqualsOrBetterThan
public static boolean isMacOSXEqualsOrBetterThan(int major_required, int minor_required) Method to determine if the current system is running a version of Mac OS X better than the given version. This is only useful for Mac OS X specific code and will not work for any other platform. -
getClassTokens
public static Map<Integer,String> getClassTokens(LWJGLUtil.TokenFilter filter, Map<Integer, String> target, Class... tokenClasses) Returns a map of public static final integer fields in the specified classes, to their String representations. An optional filter can be specified to only include specific fields. The target map may be null, in which case a new map is allocated and returned.This method is useful when debugging to quickly identify values returned from the AL/GL/CL APIs.
- Parameters:
filter
- the filter to use (optional)target
- the target map (optional)tokenClasses
- an array of classes to get tokens from- Returns:
- the token map
-

-
toHexString
Returns a string representation of the integer argument as an unsigned integer in base 16. The string will be uppercase and will have a leading '0x'.- Parameters:
value
- the integer value- Returns:
- the hex string representation
