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;

Returns

Type	Description
String	The type.

getTypeBytes()

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()
