Public methods

abstract void put(String name, float val)

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

abstract void put(String name, double val)

Put the value of the named double 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, short val)

Put the value of the named short 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, 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 1. 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.
