Method Detail

getEnv

public static JNIEnv getEnv()

Get the (static) JNIEnv for this JVM.

Returns:

the environment

getCPUArch

public static io.humble.ferry.JNIEnv.CPUArch getCPUArch(String javaCPU)

Get the CPU architecture based on the passed in javaCPUArch specifier. The string should be of a format returned from System.getProperty(String) for the property "os.arch".

Parameters:

javaCPU - the string to parse

Returns:

the CPU architecture

See Also:

System.getProperty(String)

getCPUArchFromGNUString

public static io.humble.ferry.JNIEnv.CPUArch getCPUArchFromGNUString(String gnuString)

Return a CPUArch from parsing a GNU autoconf triple. For example "x86_64-w64-mingw32" will return JNIEnv.CPUArch.X86_64 and "ppc-apple-darwin" will return JNIEnv.CPUArch.PPC.

Parameters:

gnuString - the GNU string

Returns:

the architecture

getOSFamily

public static io.humble.ferry.JNIEnv.OSFamily getOSFamily(String osName)

Get the OSFamily based on the passed in osName specifier. The string should be of a format returned from System.getProperty(String) for the property "os.name".

Parameters:

osName - the string to parse

Returns:

the OSFamily

See Also:

System.getProperty(String)

getOSFamilyFromGNUString

public static io.humble.ferry.JNIEnv.OSFamily getOSFamilyFromGNUString(String gnuString)

Return an OS Family from parsing a GNU autoconf triple. For example "x86_64-w64-mingw32" will return JNIEnv.OSFamily.WINDOWS and "ppc-apple-darwin" will return JNIEnv.OSFamily.MAC.

Parameters:

gnuString - the GNU string

Returns:

the OSFamily

getCPUArch

public io.humble.ferry.JNIEnv.CPUArch getCPUArch()

Returns:

the JNIEnv.CPUArch of this Java Virtual Machine.

getOSFamily

public io.humble.ferry.JNIEnv.OSFamily getOSFamily()

Returns:

the JNIEnv.OSFamily of this Java Virtual Machine.
