Collect implements AggregatingFunction uses ResolvesFromChildren
FinalYes
Interfaces
Methods
- __construct() : mixed
- aggregate() : void
- children() : array<int, FunctionTree>
- Every operand of this node that is an expression, in constructor order.
- outputName() : string
- Decided in the constructor, never mutated.
- references() : array<int, Reference>
- resolved() : bool
- returns() : Type<string|int, mixed>
- The element type is the reference's own declaration - over a nullable column the collected list genuinely contains nulls, so ?list<?T> is the honest shape.
- value() : array<string|int, mixed>
- withChildren() : static
- A copy of this node with $children in place of children(): same count, same order, same per-element narrowing. Never mutates $this.
