Public Methods

public abstract void put (String name, float val)

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

Parameters
name the name of the serializable field
val 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

public abstract void put (String name, double val)

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

Parameters
name the name of the serializable field
val 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

public abstract void put (String name, int val)

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

Parameters
name the name of the serializable field
val 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

public abstract void put (String name, long val)

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

Parameters
name the name of the serializable field
val 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

public abstract void put (String name, byte val)

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

Parameters
name the name of the serializable field
val 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

public abstract void put (String name, short val)

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

Parameters
name the name of the serializable field
val 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 short

public abstract void put (String name, Object val)

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

Parameters
name the name of the serializable field
val 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

public abstract void put (String name, char val)

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

Parameters
name the name of the serializable field
val 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 char

public abstract void put (String name, boolean val)

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

Parameters
name the name of the serializable field
val 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 boolean

public abstract void write (ObjectOutput out)

This method is deprecated.
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 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 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
