A unique identifier for an entity. If a key's partition ID or any of its path kinds or names are reserved/read-only, the key is reserved/read-only. A reserved/read-only key is forbidden in certain documented contexts.
- hashCode → int
The hash code for this object. [...]
- partitionId ↔ PartitionId
Entities are partitioned into subsets, currently identified by a project
ID and namespace ID. Queries are scoped to a single partition.

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.insertmay have no identifier. A path can never be empty, and a path can have at most 100 elements.read / write

A representation of the runtime type of the object.
