Syntax

public struct ScyllaTriGrid<TCell>.Enumerator

Remarks

Each call to MoveNext() checks the grid's internal version against the version captured at enumerator construction. Any mutation of the grid between calls causes MoveNext() to throw InvalidOperationException.

Constructors

Enumerator(ScyllaTriGrid<TCell>)

Initializes a new ScyllaTriGrid<TCell>.Enumerator for the specified grid, capturing its current version to enable modification detection.

Declaration

public Enumerator(ScyllaTriGrid<TCell> grid)

Parameters

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

Properties

Current

Gets the cell at the current position of the enumerator.

Declaration

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

Property Value

Type	Description
(TriCoord Coord, TCell Value)	A tuple of the TriCoord lane coordinate and the associated TCell value stored at that cell.

Methods

MoveNext()

Advances the enumerator to the next cell in row-major order.

Declaration

public bool MoveNext()

Returns

Type	Description
bool	true if the enumerator was successfully advanced to the next cell; false if the end of the grid has been reached.

Exceptions

Type	Condition
InvalidOperationException	Thrown when the grid was modified (its version changed) after this enumerator was created.
