Package org.apache.geode.pdx
Interface PdxSerializable
public interface PdxSerializable
When a domain class implements PdxSerializable it marks itself as a PDX. The implementation of
toData provides the serialization code and fromData provides
the deserialization code. These methods also define each field name and field type of the PDX.
Domain classes should serialize and deserialize all its member fields in the same order in toData
and fromData method. Also fromData and toData must read and write the same fields each time they
are called. A domain class that implements this interface must also have a public zero-arg
constructor which is used during deserialization.
Simple example:
public class User implements PdxSerializable {
private String name;
private int userId;
public User() {}
public void toData(PdxWriter out) {
out.writeString("name", this.name);
out.writeInt("userId", this.userId);
}
public void fromData(PdxReader in) {
this.name = in.readString("name");
this.userId = in.readInt("userId");
}
}
