Summary

Public constructors
PutField()

Public methods
abstract void	put(String name, double val) Put the value of the named double field into the persistent field.
abstract void	put(String name, float val) Put the value of the named float field into the persistent field.
abstract void	put(String name, int val) Put the value of the named int field into the persistent field.
abstract void	put(String name, long val) Put the value of the named long field into the persistent field.
abstract void	put(String name, byte val) Put the value of the named byte field into the persistent field.
abstract void	put(String name, Object val) Put the value of the named Object field into the persistent field.
abstract void	put(String name, short val) Put the value of the named short field into the persistent field.
abstract void	put(String name, char val) Put the value of the named char field into the persistent field.
abstract void	put(String name, boolean val) Put the value of the named boolean field into the persistent field.
abstract void	write(ObjectOutput out) This method was deprecated in API level 15. This method does not write the values contained by this PutField object in a proper format, and may result in corruption of the serialization stream. The correct way to write PutField data is by calling the ObjectOutputStream.writeFields() method.

Inherited methods

From class java.lang.Object Object clone() Creates and returns a copy of this object. boolean equals(Object obj) Indicates whether some other object is "equal to" this one. void finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. final Class<?> getClass() Returns the runtime class of this Object. int hashCode() Returns a hash code value for the object. final void notify() Wakes up a single thread that is waiting on this object's monitor. final void notifyAll() Wakes up all threads that are waiting on this object's monitor. String toString() Returns a string representation of the object. final void wait(long timeoutMillis, int nanos) Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed. final void wait(long timeoutMillis) Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed. final void wait() Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Deprecated in API level 15

public abstract void write (ObjectOutput out)

This method was deprecated in API level 15.
This method does not write the values contained by this PutField object in a proper format, and may result in corruption of the serialization stream. The correct way to write PutField data is by calling the ObjectOutputStream.writeFields() method.

Write the data and fields to the specified ObjectOutput stream, which must be the same stream that produced this PutField object.

Parameters
out	ObjectOutput: the stream to write the data and fields to

Throws
IOException	if I/O errors occur while writing to the underlying stream
IllegalArgumentException	if the specified stream is not the same stream that produced this PutField object
