Method Detail

newInstance

protected Object newInstance(com.google.protobuf.GeneratedMessageV3.UnusedPrivateParameter unused)

Overrides:

newInstance in class com.google.protobuf.GeneratedMessageV3

getUnknownFields

public final com.google.protobuf.UnknownFieldSet getUnknownFields()

Specified by:

getUnknownFields in interface com.google.protobuf.MessageOrBuilder

Overrides:

getUnknownFields in class com.google.protobuf.GeneratedMessageV3

getDescriptor

public static final com.google.protobuf.Descriptors.Descriptor getDescriptor()

internalGetFieldAccessorTable

protected com.google.protobuf.GeneratedMessageV3.FieldAccessorTable internalGetFieldAccessorTable()

Specified by:

internalGetFieldAccessorTable in class com.google.protobuf.GeneratedMessageV3

getChildIndex

public int getChildIndex()

 The node to which the link points.
 

int32 child_index = 1;

Specified by:

getChildIndex in interface PlanNode.ChildLinkOrBuilder

Returns:

The childIndex.

getType

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;

Specified by:

getType in interface PlanNode.ChildLinkOrBuilder

Returns:

The type.

getTypeBytes

public com.google.protobuf.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;

Specified by:

getTypeBytes in interface PlanNode.ChildLinkOrBuilder

Returns:

The bytes for type.

getVariable

public String getVariable()

 Only present if the child node is [SCALAR][google.spanner.v1.PlanNode.Kind.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;

Specified by:

getVariable in interface PlanNode.ChildLinkOrBuilder

Returns:

The variable.

getVariableBytes

public com.google.protobuf.ByteString getVariableBytes()

 Only present if the child node is [SCALAR][google.spanner.v1.PlanNode.Kind.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;

Specified by:

getVariableBytes in interface PlanNode.ChildLinkOrBuilder

Returns:

The bytes for variable.
