wrap
public Operator wrap(Operator op)
Description copied from interface:OperatorFactory

op
- the Operator to wrap- Returns:

validateEquivalent
public boolean validateEquivalent(OperatorFactory other)
Description copied from interface:OperatorFactory
Validates the equivalence of Operators. This is similar to @{code .equals} but is its own method so that it can ignore certain fields that would be important for a true equality check. Namely, two Operators defined the same way but with different output names can be considered equivalent even though they are not equal.This primarily exists to simplify tests, where this equivalence can be used to validate that the Operators created by the SQL planner are actually equivalent to what we expect without needing to be overly dependent on how the planner names output columns
- Specified by:
validateEquivalent
in interfaceOperatorFactory
- Parameters:
other
- the processor to test equivalence of- Returns:
- boolean identifying if these processors should be considered equivalent to each other.
