Constructor Details
#initialize(**args) ⇒ PlanNode
Returns a new instance of PlanNode
| 1793 1794 1795 | # File 'generated/google/apis/spanner_v1/classes.rb', line 1793 def initialize(**args) update!(**args) end | 
Instance Attribute Details
#child_links ⇒ Array<Google::Apis::SpannerV1::ChildLink>
List of child node indexes and their relationship to this parent.
Corresponds to the JSON property childLinks
| 1747 1748 1749 | # File 'generated/google/apis/spanner_v1/classes.rb', line 1747 def child_links @child_links end | 
#display_name ⇒ String
The display name for the node.
Corresponds to the JSON property displayName
| 1752 1753 1754 | # File 'generated/google/apis/spanner_v1/classes.rb', line 1752 def display_name @display_name end | 
#execution_stats ⇒ Hash<String,Object>
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.
Corresponds to the JSON property executionStats
| 1760 1761 1762 | # File 'generated/google/apis/spanner_v1/classes.rb', line 1760 def execution_stats @execution_stats end | 
#index ⇒ Fixnum
The PlanNode's index in node list.
Corresponds to the JSON property index
| 1765 1766 1767 | # File 'generated/google/apis/spanner_v1/classes.rb', line 1765 def index @index end | 
#kind ⇒ String
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.
Corresponds to the JSON property kind
| 1774 1775 1776 | # File 'generated/google/apis/spanner_v1/classes.rb', line 1774 def kind @kind end | 
#metadata ⇒ Hash<String,Object>
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"
Corresponds to the JSON property metadata
| 1785 1786 1787 | # File 'generated/google/apis/spanner_v1/classes.rb', line 1785 def @metadata end | 
#short_representation ⇒ Google::Apis::SpannerV1::ShortRepresentation
Condensed representation of a node and its subtree. Only present for
SCALAR PlanNode(s).
Corresponds to the JSON property shortRepresentation
| 1791 1792 1793 | # File 'generated/google/apis/spanner_v1/classes.rb', line 1791 def short_representation @short_representation end |
