Provide programmatic access to the persistent fields to be written to ObjectOutput.

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.

put

public abstract void put (String name, 
                double val)

Put the value of the named double field into the persistent field.

Parameters
`name`	`String`: the name of the serializable field
`val`	`double`: the value to assign to the field

Throws
`IllegalArgumentException`	if `name` does not match the name of a serializable field for the class whose fields are being written, or if the type of the named field is not `double`

put

public abstract void put (String name, 
                float val)

Put the value of the named float field into the persistent field.

Parameters
`name`	`String`: the name of the serializable field
`val`	`float`: the value to assign to the field

Throws
`IllegalArgumentException`	if `name` does not match the name of a serializable field for the class whose fields are being written, or if the type of the named field is not `float`

put

public abstract void put (String name, 
                int val)

Put the value of the named int field into the persistent field.

Parameters
`name`	`String`: the name of the serializable field
`val`	`int`: the value to assign to the field

Throws
`IllegalArgumentException`	if `name` does not match the name of a serializable field for the class whose fields are being written, or if the type of the named field is not `int`

put

public abstract void put (String name, 
                long val)

Parameters
`name`	`String`: the name of the serializable field
`val`	`long`: the value to assign to the field

Throws
`IllegalArgumentException`	if `name` does not match the name of a serializable field for the class whose fields are being written, or if the type of the named field is not `long`

put

public abstract void put (String name, 
                byte val)

Put the value of the named byte field into the persistent field.

Parameters
`name`	`String`: the name of the serializable field
`val`	`byte`: the value to assign to the field

Throws
`IllegalArgumentException`	if `name` does not match the name of a serializable field for the class whose fields are being written, or if the type of the named field is not `byte`

put

public abstract void put (String name, 
                Object val)

Put the value of the named Object field into the persistent field.

Parameters
`name`	`String`: the name of the serializable field
`val`	`Object`: the value to assign to the field (which may be `null`)

Throws
`IllegalArgumentException`	if `name` does not match the name of a serializable field for the class whose fields are being written, or if the type of the named field is not a reference type

write

public abstract void write (ObjectOutput out)

`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
