com.gigaspaces.document
Class SpaceDocument

java.lang.Object
  com.gigaspaces.document.SpaceDocument

All Implemented Interfaces:

com.gigaspaces.entry.VirtualEntry, Externalizable, Serializable

public class SpaceDocument
extends Object
implements com.gigaspaces.entry.VirtualEntry, Externalizable

Represents a document which can be stored and retrieved from the space. A document is a collection of properties (which are name-value pairs) associated with a type. A property name is a string. A property value can be of any type, but it is usually either a scalar (e.g. int, String, Date, etc.), a set of properties (either Map or DocumentProperties), or an array/collection or scalars or maps. Documents of the same type can have different properties, which provides more dynamic schema than POJOs.
