WindowFunction extends FunctionTree

apply() : mixed
children() : array<int, FunctionTree>: Every operand of this node that is an expression, in constructor order.
over() : static: Returns a copy bound to $window. Never mutates $this.
resolved() : bool: True when this node and every node in children() can answer returns().
returns() : Type<string|int, mixed>: An OptionalType return declares the produced column nullable; there is no nullable() peer.
toString() : string
window() : Window
withChildren() : static: A copy of this node with $children in place of children(): same count, same order, same per-element narrowing. Never mutates $this.


    public
                    apply(WindowContext $window) : mixed

Every operand of this node that is an expression, in constructor order.


    public
                    children() : array<int, FunctionTree>

Raw scalars, enums, Types and scope-introducing bodies are fields, not children.

array<int, FunctionTree>

Returns a copy bound to $window. Never mutates $this.


    public
                    over(Window $window) : static

static

True when this node and every node in children() can answer returns().


    public
                    resolved() : bool

bool

An OptionalType return declares the produced column nullable; there is no nullable() peer.


    public
                    returns() : Type<string|int, mixed>

The frame contributes nothing to the type - Window is a field, not a parameter.

Type<string|int, mixed>


    public
                    toString() : string

string


    public
                    window() : Window

Window

A copy of this node with $children in place of children(): same count, same order, same per-element narrowing. Never mutates $this.


    public
                    withChildren(array<int, FunctionTree> $children) : static
