Class Overview

Signals that the ObjectInputStream class encountered a primitive type (int, char etc.) instead of an object instance in the input stream.

Fields
public boolean	eof	`true` indicates that there is no more primitive data available.
public int	length	The number of bytes of primitive data (int, char, long etc.) that are available.

Inherited Methods

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 extra information message which was provided when this `Throwable` was created.
String	getMessage() Returns the extra information message which was provided when this `Throwable` was created.
StackTraceElement[]	getStackTrace() Returns the array of stack trace elements of this `Throwable`.
Throwable	initCause(Throwable throwable) Initializes the cause of this `Throwable`.
void	printStackTrace(PrintWriter err) Writes a printable representation of this `Throwable`'s stack trace to the specified print writer.
void	printStackTrace(PrintStream err) Writes a printable representation of this `Throwable`'s stack trace to the specified print stream.
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.

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() Called before the object's memory is reclaimed by the VM.
final Class<? extends Object>	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.
