TypeDescription
PlanNode.ChildLink.Builder
Overrides
public PlanNode.ChildLink.Builder clearType()

The type of the link. For example, in Hash Joins this could be used to distinguish between the build child and the probe child, or in the case of the child being an output variable, to represent the tag associated with the output variable.

string type = 2;

Returns
TypeDescription
PlanNode.ChildLink.Builder

This builder for chaining.

public PlanNode.ChildLink.Builder clearVariable()

Only present if the child node is SCALAR and corresponds to an output variable of the parent node. The field carries the name of the output variable. For example, a TableScan operator that reads rows from a table will have child links to the SCALAR nodes representing the output variables created for each column that is read by the operator. The corresponding variable fields will be set to the variable names assigned to the columns.

string variable = 3;

Returns
TypeDescription

Returns
TypeDescription
PlanNode.ChildLink.Builder
Overrides
public int getChildIndex()

The node to which the link points.

int32 child_index = 1;

Returns
TypeDescription
int

The childIndex.

public PlanNode.ChildLink getDefaultInstanceForType()
Returns

public Descriptors.Descriptor getDescriptorForType()
Returns
TypeDescription
Descriptor
Overrides
public String getType()

The type of the link. For example, in Hash Joins this could be used to distinguish between the build child and the probe child, or in the case of the child being an output variable, to represent the tag associated with the output variable.

string type = 2;

Returns
TypeDescription
String

The type.

public ByteString getTypeBytes()

The type of the link. For example, in Hash Joins this could be used to distinguish between the build child and the probe child, or in the case of the child being an output variable, to represent the tag associated with the output variable.

string type = 2;

Returns
TypeDescription
ByteString

The bytes for type.

public String getVariable()

Only present if the child node is SCALAR and corresponds to an output variable of the parent node. The field carries the name of the output variable. For example, a TableScan operator that reads rows from a table will have child links to the SCALAR nodes representing the output variables created for each column that is read by the operator. The corresponding variable fields will be set to the variable names assigned to the columns.

string variable = 3;

Returns
