    • mapLibraryName

      public static String mapLibraryName(String name)
      Wraps System.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
    • getPrivilegedBoolean

      public static boolean getPrivilegedBoolean(String property_name)
      Gets a boolean property as a privileged action.
    • getPrivilegedInteger

      public static Integer getPrivilegedInteger(String property_name)
      Gets an integer property as a privileged action.
      Parameters:
      property_name - the integer property name
      Returns:
      the property value
    • getPrivilegedInteger

      public static Integer getPrivilegedInteger(String property_name, int default_val)
      Gets an integer property as a privileged action.
      Parameters:
      property_name - the integer property name
      default_val - the default value to use if the property is not defined
      Returns:
      the property value
    • log

      public static void log(CharSequence msg)
      Prints the given message to System.err if DEBUG is true.
      Parameters:
      msg - Message to print
    • isMacOSXEqualsOrBetterThan

      public static boolean isMacOSXEqualsOrBetterThan(int major_required, int minor_required)

    • 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
    • getClassTokens

      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 - the classes to get tokens from
      Returns:

      Parameters:
      value - the integer value
      Returns:
      the hex string representation
