Interface KeyOrBuilder (2.21.3) 

public interface KeyOrBuilder extends MessageOrBuilder

Implements

MessageOrBuilder

Methods

getPartitionId()

public abstract PartitionId getPartitionId()

Entities are partitioned into subsets, currently identified by a project ID and namespace ID. Queries are scoped to a single partition.

.google.datastore.v1.PartitionId partition_id = 1;

Returns
Type Description
PartitionId

The partitionId.

getPartitionIdOrBuilder()

public abstract PartitionIdOrBuilder getPartitionIdOrBuilder()

Entities are partitioned into subsets, currently identified by a project ID and namespace ID. Queries are scoped to a single partition.

.google.datastore.v1.PartitionId partition_id = 1;

Returns
Type Description
PartitionIdOrBuilder

getPath(int index)

public abstract Key.PathElement getPath(int index)

The entity path. An entity path consists of one or more elements composed of a kind and a string or numerical identifier, which identify entities. The first element identifies a root entity, the second element identifies a child of the root entity, the third element identifies a child of the second entity, and so forth. The entities identified by all prefixes of the path are called the element's ancestors.

An entity path is always fully complete: all of the entity's ancestors are required to be in the path along with the entity identifier itself. The only exception is that in some documented cases, the identifier in the last path element (for the entity) itself may be omitted. For example, the last path element of the key of Mutation.insert may have no identifier.

A path can never be empty, and a path can have at most 100 elements.

repeated .google.datastore.v1.Key.PathElement path = 2;

Parameter
Name Description
index int
Returns
Type Description
Key.PathElement
