ErrnoException

A checked exception thrown when Os methods fail. This exception contains the native errno value, for comparison against the constants in OsConstants, should sophisticated callers need to adjust their behavior based on the exact failure.

Summary

Fields
public final int	errno	The errno value, for comparison with the `E` constants in `OsConstants`.

Fields

public final int

errno

The errno value, for comparison with the E constants in OsConstants.

Public Constructors
	ErrnoException(String functionName, int errno) Constructs an instance with the given function name and errno value.
	ErrnoException(String functionName, int errno, Throwable cause) Constructs an instance with the given function name, errno value, and cause.

Inherited Methods

From class java.lang.Throwable

final void	addSuppressed(Throwable throwable) Adds `throwable` to the list of throwables suppressed by this.
Throwable	fillInStackTrace() Records the stack trace from the point where this method has been called to this `Throwable`.
Throwable	getCause() Returns the cause of this `Throwable`, or `null` if there is no cause.
String	getLocalizedMessage() Returns the detail message which was provided when this `Throwable` was created.
String	getMessage() Returns the detail message which was provided when this `Throwable` was created.
StackTraceElement[]	getStackTrace() Returns a clone of the array of stack trace elements of this `Throwable`.
final Throwable[]	getSuppressed() Returns the throwables suppressed by this.
Throwable	initCause(Throwable throwable) Initializes the cause of this `Throwable`.
void	printStackTrace(PrintStream err) Writes a printable representation of this `Throwable`'s stack trace to the given print stream.
void	printStackTrace(PrintWriter err) Writes a printable representation of this `Throwable`'s stack trace to the specified print writer.
void	printStackTrace() Writes a printable representation of this `Throwable`'s stack trace to the `System.err` stream.
void	setStackTrace(StackTraceElement[] trace) Sets the array of stack trace elements.
String	toString() Returns a string containing a concise, human-readable description of this object.

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Public Constructors

public ErrnoException (String functionName, int errno)

Added in API level 21

Constructs an instance with the given function name and errno value.

public ErrnoException (String functionName, int errno, Throwable cause)

Added in API level 21

Constructs an instance with the given function name, errno value, and cause.

Public Methods

public String getMessage ()

Added in API level 21

Converts the stashed function name and errno value to a human-readable string. We do this here rather than in the constructor so that callers only pay for this if they need it.
