public interface PdxWriter
toData or
PdxSerializer toData by GemFire when it is serializing the
domain class. The domain class needs to serialize instance
fields using this interface. This interface is implemented
by GemFire.
The order in which the fields are written must match the order in which they are
read by PdxReader.
Field names are case sensitive.
All methods on this interface return itself to allow method calls to be chained together.

It is best to use one of the other writeXXX methods if your field type will always be XXX. This method allows the field value to be anything that is an instance of Object. This gives you more flexibility but more space is used to store the serialized field.
Note that some Java objects serialized with this method may not be compatible with non-java languages.
To ensure that only portable objects are serialized use writeObject(String, Object, boolean).

If it can not find a specific match to a writeXXX method it will call writeObject.
This method may serialize objects that are not portable to non-java languages.
To ensure that only objects that are portable to non-java languages are serialized use writeField(String, Object, Class, boolean) instead.

or when a client executes a query on a server.
The fields that are marked as identity fields are used to generate the hashCode and
equals methods of PdxInstance. Because of this, the identity fields should themselves
either be primitives, or implement hashCode and equals.
If no fields are set as identity fields, then all fields will be used in hashCode and equals
checks.
The identity fields should make marked after they are written using a write* method.fieldName - the name of the field to mark as an identity field.PdxFieldDoesNotExistException - if the named field has not already been written.Copyright © 1997-2017 Pivotal Software, Inc. All rights reserved.
