class AggregateExpressionResolver extends TreeNodeResolver[AggregateExpression, Expression] with ResolvesExpressionChildren

A resolver for AggregateExpressions which are introduced while resolving an UnresolvedFunction. It is responsible for the following:

  • Handling of the exceptions related to AggregateExpressions.
  • Updating the ExpressionResolver.expressionResolutionContextStack.
  • Applying type coercion rules to the AggregateExpressionss children. This is the only resolution that we apply here as we already resolved the children of AggregateExpression in the FunctionResolver.

    Resolves the given AggregateExpression by applying:

    • Type coercion rules
    • Validity checks. Those include:
      • Whether the AggregateExpression is under a valid operator.
      • Whether there is a nested AggregateExpression.
      • Whether there is a nondeterministic child.
    • Updates to the ExpressionResolver.expressionResolutionContextStack
