Method Detail

error

public void error(jnr.constants.platform.Errno error,
                  String extraData)

Specified by:

error in interface POSIXHandler

unimplementedError

public void unimplementedError(String methodName)

Description copied from interface: POSIXHandler

Specify that posix method is unimplemented. In JRuby we generate an exception with this.

Specified by:

unimplementedError in interface POSIXHandler

warn

public void warn(POSIXHandler.WARNING_ID id,
                 String message,
                 Object... data)

Specified by:

warn in interface POSIXHandler

isVerbose

public boolean isVerbose()

Description copied from interface: POSIXHandler

Should we provide verbose output about POSIX activities

Specified by:

isVerbose in interface POSIXHandler

getCurrentWorkingDirectory

public File getCurrentWorkingDirectory()

Description copied from interface: POSIXHandler

Get current working directory of your runtime.

Specified by:

getCurrentWorkingDirectory in interface POSIXHandler

getEnv

public String[] getEnv()

Description copied from interface: POSIXHandler

Get current set of environment variables of your runtime.

Specified by:

getEnv in interface POSIXHandler

getInputStream

public InputStream getInputStream()

Description copied from interface: POSIXHandler

Get your runtime's current InputStream

Specified by:

getInputStream in interface POSIXHandler

getOutputStream

public PrintStream getOutputStream()

Description copied from interface: POSIXHandler

Get your runtime's current OutputStream

Specified by:

getOutputStream in interface POSIXHandler

getPID

public int getPID()

Description copied from interface: POSIXHandler

Get your runtimes process ID. This is only intended for non-native POSIX support (e.g. environments where JNA cannot load or security restricted environments). In JRuby we found a number of packages which would rather have some identity for the runtime than nothing. Note: If you do not want this to work you impl can just call unimplementedError(String).

Specified by:

getPID in interface POSIXHandler

getErrorStream

public PrintStream getErrorStream()

Description copied from interface: POSIXHandler

Get your runtime's current ErrorStream

Specified by:

getErrorStream in interface POSIXHandler
