Methods
equals(Object obj)
public boolean equals ( Object obj )
Parameter Name Description obj
Object
Overrides
getChildIndex()
public int getChildIndex ()
The node to which the link points.
int32 child_index = 1;
Returns Type Description int
The childIndex.
getDefaultInstanceForType()
public PlanNode . ChildLink getDefaultInstanceForType ()
getParserForType()
public Parser<PlanNode . ChildLink> getParserForType ()
Overrides
getSerializedSize()
public int getSerializedSize ()
Returns Type Description int
Overrides
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 Type Description String
The type.
getTypeBytes()
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 Type Description ByteString
The bytes for type.
getUnknownFields()
public final UnknownFieldSet getUnknownFields ()
Overrides
getVariable()
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 Type Description String
The variable.
getVariableBytes()
public ByteString getVariableBytes ()
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 Type Description ByteString
The bytes for variable.
hashCode()
Returns Type Description int
