Methods

#distinct_on

def distinct_on() -> ::Array<::Google::Cloud::Datastore::V1::PropertyReference>

Returns

(::Array<::Google::Cloud::Datastore::V1::PropertyReference>) —
The properties to make distinct. The query results will contain the first result for each distinct combination of values for the given properties (if empty, all results are returned).

Requires:
- If order is specified, the set of distinct on properties must appear before the non-distinct on properties in order.

#distinct_on=

def distinct_on=(value) -> ::Array<::Google::Cloud::Datastore::V1::PropertyReference>

Parameter

value (::Array<::Google::Cloud::Datastore::V1::PropertyReference>) —
The properties to make distinct. The query results will contain the first result for each distinct combination of values for the given properties (if empty, all results are returned).

Requires:
- If order is specified, the set of distinct on properties must appear before the non-distinct on properties in order.

Returns

(::Array<::Google::Cloud::Datastore::V1::PropertyReference>) —
The properties to make distinct. The query results will contain the first result for each distinct combination of values for the given properties (if empty, all results are returned).

Requires:
- If order is specified, the set of distinct on properties must appear before the non-distinct on properties in order.

#end_cursor

def end_cursor() -> ::String

Returns

(::String) — An ending point for the query results. Query cursors are returned in query result batches and can only be used to limit the same query.

#end_cursor=

def end_cursor=(value) -> ::String

Parameter

value (::String) — An ending point for the query results. Query cursors are returned in query result batches and can only be used to limit the same query.

Returns

(::String) — An ending point for the query results. Query cursors are returned in query result batches and can only be used to limit the same query.

#filter

def filter() -> ::Google::Cloud::Datastore::V1::Filter

Returns

(::Google::Cloud::Datastore::V1::Filter) — The filter to apply.

#filter=

def filter=(value) -> ::Google::Cloud::Datastore::V1::Filter

Parameter

value (::Google::Cloud::Datastore::V1::Filter) — The filter to apply.

Returns

(::Google::Cloud::Datastore::V1::Filter) — The filter to apply.

#kind

def kind() -> ::Array<::Google::Cloud::Datastore::V1::KindExpression>

Returns

(::Array<::Google::Cloud::Datastore::V1::KindExpression>) — The kinds to query (if empty, returns entities of all kinds). Currently at most 1 kind may be specified.

#kind=

def kind=(value) -> ::Array<::Google::Cloud::Datastore::V1::KindExpression>

Parameter

value (::Array<::Google::Cloud::Datastore::V1::KindExpression>) — The kinds to query (if empty, returns entities of all kinds). Currently at most 1 kind may be specified.

Returns

(::Array<::Google::Cloud::Datastore::V1::KindExpression>) — The kinds to query (if empty, returns entities of all kinds). Currently at most 1 kind may be specified.

#limit

def limit() -> ::Google::Protobuf::Int32Value

Returns

(::Google::Protobuf::Int32Value) — The maximum number of results to return. Applies after all other constraints. Optional. Unspecified is interpreted as no limit. Must be >= 0 if specified.

#limit=

def limit=(value) -> ::Google::Protobuf::Int32Value

Parameter

value (::Google::Protobuf::Int32Value) — The maximum number of results to return. Applies after all other constraints. Optional. Unspecified is interpreted as no limit. Must be >= 0 if specified.

Returns

(::Google::Protobuf::Int32Value) — The maximum number of results to return. Applies after all other constraints. Optional. Unspecified is interpreted as no limit. Must be >= 0 if specified.

#offset

def offset() -> ::Integer

Returns

(::Integer) — The number of results to skip. Applies before limit, but after all other constraints. Optional. Must be >= 0 if specified.

#offset=

def offset=(value) -> ::Integer

Parameter

value (::Integer) — The number of results to skip. Applies before limit, but after all other constraints. Optional. Must be >= 0 if specified.

Returns

(::Integer) — The number of results to skip. Applies before limit, but after all other constraints. Optional. Must be >= 0 if specified.

#order

def order() -> ::Array<::Google::Cloud::Datastore::V1::PropertyOrder>

Returns

(::Array<::Google::Cloud::Datastore::V1::PropertyOrder>) — The order to apply to the query results (if empty, order is unspecified).

#order=

def order=(value) -> ::Array<::Google::Cloud::Datastore::V1::PropertyOrder>

Parameter

value (::Array<::Google::Cloud::Datastore::V1::PropertyOrder>) — The order to apply to the query results (if empty, order is unspecified).

Returns

(::Array<::Google::Cloud::Datastore::V1::PropertyOrder>) — The order to apply to the query results (if empty, order is unspecified).

#projection

def projection() -> ::Array<::Google::Cloud::Datastore::V1::Projection>

Returns

(::Array<::Google::Cloud::Datastore::V1::Projection>) — The projection to return. Defaults to returning all properties.

#projection=

def projection=(value) -> ::Array<::Google::Cloud::Datastore::V1::Projection>

Parameter

value (::Array<::Google::Cloud::Datastore::V1::Projection>) — The projection to return. Defaults to returning all properties.

Returns

(::Array<::Google::Cloud::Datastore::V1::Projection>) — The projection to return. Defaults to returning all properties.

#start_cursor

def start_cursor() -> ::String

Returns

(::String) — A starting point for the query results. Query cursors are returned in query result batches and can only be used to continue the same query.

#start_cursor=

def start_cursor=(value) -> ::String

Parameter

value (::String) — A starting point for the query results. Query cursors are returned in query result batches and can only be used to continue the same query.

Returns

(::String) — A starting point for the query results. Query cursors are returned in query result batches and can only be used to continue the same query.
