Syntax

public struct ScyllaSquareGrid<TCell>.Enumerator

Remarks

Yields (SquareCoord Coord, TCell Value) tuples in row-major order (left to right within each row, top to bottom across rows). The enumerator captures the grid's internal version at construction and throws InvalidOperationException if the grid is mutated during iteration.

Constructors

Enumerator(ScyllaSquareGrid<TCell>)

Initializes a new ScyllaSquareGrid<TCell>.Enumerator for the given grid.

Declaration

public Enumerator(ScyllaSquareGrid<TCell> grid)

Parameters

Type	Name	Description
ScyllaSquareGrid<TCell>	grid	The grid to enumerate. Must not be null.

Properties

Current

Gets the coordinate and cell value at the current iteration position.

Declaration

public readonly (SquareCoord Coord, TCell Value) Current { get; }

Property Value

Type	Description
(SquareCoord Coord, TCell Value)	A tuple (SquareCoord Coord, TCell Value). Undefined before the first MoveNext() call or after MoveNext() returns false.

Methods

MoveNext()

Advances the enumerator to the next cell.

Declaration

public bool MoveNext()

Returns

Type	Description
bool	true if the enumerator was successfully advanced and Current is valid; false if all cells have been visited.

Exceptions

Type	Condition
InvalidOperationException	Thrown if the grid was modified (via any setter or Fill(TCell)) after this enumerator was created.
