__construct
Constructor.
| Parameters | |
|---|---|
| Name | Description |
data |
array
Optional. Data for populating the Message object. |
↳ index |
int
The |
↳ kind |
int
Used to determine the type of node. May be needed for visualizing different kinds of nodes differently. For example, If the node is a SCALAR node, it will have a condensed representation which can be used to directly embed a description of the node in its parent. |
↳ display_name |
string
The display name for the node. |
↳ child_links |
array<Google\Cloud\Spanner\V1\PlanNode\ChildLink>
List of child node |
↳ short_representation |
Google\Cloud\Spanner\V1\PlanNode\ShortRepresentation
Condensed representation for SCALAR nodes. |
↳ metadata |
Google\Protobuf\Struct
Attributes relevant to the node contained in a group of key-value pairs. For example, a Parameter Reference node could have the following information in its metadata: { "parameter_reference": "param1", "parameter_type": "array" } |
↳ execution_stats |
Google\Protobuf\Struct
The execution statistics associated with the node, contained in a group of key-value pairs. Only present if the plan was returned as a result of a profile query. For example, number of executions, number of rows/time per execution etc. |
getIndex
The PlanNode's index in node list.
| Returns | |
