public sealed class EntityFilter : IMessage<EntityFilter>, IEquatable<EntityFilter>, IDeepCloneable<EntityFilter>, IBufferMessage, IMessage
Reference documentation and code samples for the Cloud Datastore v1 API class EntityFilter.
Identifies a subset of entities in a project. This is specified as
combinations of kinds and namespaces (either or both of which may be all, as
described in the following examples).
Example usage:
Entire project:
kinds=[], namespace_ids=[]
Kinds Foo and Bar in all namespaces:
kinds=['Foo', 'Bar'], namespace_ids=[]
Kinds Foo and Bar only in the default namespace:
kinds=['Foo', 'Bar'], namespace_ids=['']
Kinds Foo and Bar in both the default and Baz namespaces:
kinds=['Foo', 'Bar'], namespace_ids=['', 'Baz']
The entire Baz namespace:
kinds=[], namespace_ids=['Baz']
public RepeatedField<string> NamespaceIds { get; }
An empty list represents all namespaces. This is the preferred
usage for projects that don't use namespaces.
An empty string element represents the default namespace. This should be
used if the project has data in non-default namespaces, but doesn't want to
include them.
Each namespace in this list must be unique.
