public final class Entity
extends com.google.api.client.json.GenericJson

A Datastore data object. An entity is limited to 1 megabyte when stored. That _roughly_ corresponds to a limit of 1 megabyte for the serialized form of this message.

This is the Java data model class that specifies how to parse/serialize into the JSON that is transmitted over HTTP when working with the Cloud Datastore API. For a detailed explanation see: https://developers.google.com/api-client-library/java/google-http-java-client/json

Method Detail

getKey

public Key getKey()

The entity's key. An entity must have a key, unless otherwise documented (for example, an entity in `Value.entity_value` may have no key). An entity's kind is its key path's last element's kind, or null if it has no key.

Returns:

value or null for none

setKey

public Entity setKey(Key key)

The entity's key. An entity must have a key, unless otherwise documented (for example, an entity in `Value.entity_value` may have no key). An entity's kind is its key path's last element's kind, or null if it has no key.

Parameters:

key - key or null for none

getProperties

public java.util.Map<java.lang.String,Value> getProperties()

The entity's properties. The map's keys are property names. A property name matching regex `__.*__` is reserved. A reserved property name is forbidden in certain documented contexts. The name must not contain more than 500 characters. The name cannot be `""`.

Returns:

value or null for none

setProperties

public Entity setProperties(java.util.Map<java.lang.String,Value> properties)

The entity's properties. The map's keys are property names. A property name matching regex `__.*__` is reserved. A reserved property name is forbidden in certain documented contexts. The name must not contain more than 500 characters. The name cannot be `""`.

Parameters:

properties - properties or null for none

set

public Entity set(java.lang.String fieldName,
                  java.lang.Object value)

Overrides:

set in class com.google.api.client.json.GenericJson

clone

public Entity clone()

Overrides:

clone in class com.google.api.client.json.GenericJson
