clearChildIndex()
public PlanNode.ChildLink.Builder clearChildIndex()
The node to which the link points.

public PlanNode.ChildLink.Builder clearOneof(Descriptors.OneofDescriptor oneof)
Parameter
Returns
Overrides
clearType()
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;
clearVariable()
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;
clone()
public PlanNode.ChildLink.Builder clone()
Returns
Overrides
getChildIndex()
public int getChildIndex()
The node to which the link points.
int32 child_index = 1;
| Type | Description |
| int | The childIndex.

getTypeBytes()
public ByteString getTypeBytes()
