Inherited Methods

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 Methods

public abstract boolean defaulted (String name)

Since: API Level 1

Indicates if the field identified by name is defaulted. This means that it has no value in this stream.

Parameters

name	the name of the field to check.

Returns

true if the field is defaulted, false otherwise.

Throws

IllegalArgumentException	if `name` does not identify a serializable field.
IOException	if an error occurs while reading from the source input stream.

public abstract byte get (String name, byte defaultValue)

Since: API Level 1

Gets the value of the byte field identified by name from the persistent field.

Parameters

name	the name of the field to get.
defaultValue	the default value that is used if the field does not have a value when read from the source stream.

Returns

the value of the field identified by name.

Throws

IOException	if an error occurs while reading from the source input stream.
IllegalArgumentException	if the type of the field identified by `name` is not `byte`.

public abstract long get (String name, long defaultValue)

Since: API Level 1

Parameters

name	the name of the field to get.
defaultValue	the default value that is used if the field does not have a value when read from the source stream.

Returns

the value of the field identified by name.

Throws

IOException	if an error occurs while reading from the source input stream.
