Method Summary

Modifier and Type	Method and Description
public final int	Returns: the size of a pointer in bits addressSize() Deprecated Use `Runtime#addressSize()` instead. Gets the size of a C address/pointer on the native platform.
private static int	calculateAddressSize(Platform.CPU cpu)
private static Platform.CPU	determineCPU()
private static Platform.OS	Returns: An member of the `OS` enum. determineOS() Determines the operating system jffi is running on
private static Platform	Returns: An instance of `Platform` determinePlatform(Platform.OS The operating system. os) Determines the `Platform` that best describes the `OS`
private static Platform	determinePlatform()
private static boolean	equalsIgnoreCase(String s1, String s2)
public final Platform.CPU	Returns: A `CPU` value representing the current processor architecture. getCPU() Gets the current processor architecture the JVM is running on.
public String	Returns: The name of this platform. getName() Gets the name of this `Platform`.
public static Platform	Returns: The current platform. getNativePlatform() Gets the native `Platform`
public final Platform.OS	Returns: A `OS` value representing the current Operating System. getOS() Gets the current Operating System.
public final String	Returns: the String representing the OS name from the System property `os.name` or null if none was found This is not the same as `getOS()` which returns the `OS`. For example: Mac OS X is the `OS#DARWIN` `OS` but returns "Mac OS X" from this method getOSName()
public static Platform	getPlatform() Deprecated
public String	Returns: The standard C library name getStandardCLibraryName() Returns the platform specific standard C library name
public String	Returns: the String representing the version of this platform, or null if none could be found getVersion() Gets the version of this platform as specified by the system property "os.version"
public int	Returns: the number representing the major version of this platform or -1 if none was found getVersionMajor() Gets the number representing the major version of this platform This uses the first number from `getVersion()`
public int	Returns: the number representing the minor version of this platform or -1 if none was found getVersionMinor() Gets the number representing the minor version of this platform This uses the second number from `getVersion()`
private List<String>	Returns: the list of version numbers found from `getVersion()` or an empty list if none were found getVersionNumbers()
public final boolean	Returns: true if this platform is 32 bit, else false Note: do not use this to determine long size, instead use `Runtime#longSize()` is32Bit()
public final boolean	Returns: true if this platform is 64 bit, else false Note: do not use this to determine long size, instead use `Runtime#longSize()` is64Bit()
public final boolean	Returns: true if big endian, false otherwise or if cannot determine isBigEndian() Returns true if the current platform is big endian
public final boolean	isBSD()
public final boolean	Returns: true if little endian, false otherwise or if cannot determine isLittleEndian() Returns true if the current platform is little endian
public final boolean	isUnix()
public List<String>	Returns: the list of absolute paths where the library was found libraryLocations(String the base name (e.g. "c") of the library to locate libName, List<String> additional paths to search, these take precedence over default paths, (as is the behavior in `LibraryLoader`) pass null to only search in the default paths additionalPaths) Returns a list of absolute paths to the found locations of a library with the base name `libName`, if the returned list is empty then the library could not be found and will fail to be loaded as a result.
public String	Returns: the path of the library locateLibrary(String the base name (e.g. "c") of the library to locate libName, List<String> the list of directories to search libraryPath) Searches through a list of directories for a native library.
public String	Returns: the path of the library locateLibrary(String the base name (e.g. "c") of the library to locate libName, List<String> the list of directories to search libraryPaths, Map<LibraryOption, Object> map of `LibraryOption`s to customize search behavior such as `LibraryOption#PreferCustomPaths` options) Searches through a list of directories for a native library.
public final int	Returns: the size of a long in bits longSize() Deprecated Use `Runtime#longSize()` instead. Gets the size of a C 'long' on the native platform.
public String	Returns: The mapped library name. mapLibraryName(String The library name to map libName) Maps from a generic library name (e.g. "c") to the platform specific library name.
private static boolean	startsWithIgnoreCase(String s1, String s2)
